The food market for network technologies for information centers is developing rapidly. The simplicity and flexibility of network architecture is growing, but accessibility stiff paramount. Corporate customers should appraise the several vendor approaches and architectures, with particular emphasis on software-relevant capabilities.

Commercialise Definition / Description

Network technologies for data centers provide a ordered and / or physical network connection between corporate information centers. Data center network requirements began to grow rapidly later a period of discipline stability that lasted much 15 years. Piece speed, density, and scale increased during this period of time, the underlying architecture relied on an aging three-tier hierarchical approach.

Under the cut of Gartner analysts of the major data central securities industry players, the

new style of Internet-oriented IT, which whole caboodle in large-graduated table organizations such as Google, Facebook and Virago, has changed the paradigm of Information technology services. Advanced and mainstream enterprise-level organizations are currently trying to reach improved flexibleness, better management and / or turn down costs for their modules.

The impact and lessons learned from deploying cloud systems at big enterprises had life-threatening consequences for the initiative-level data center electronic network engineering science market, which, supported connected which, enterprises of untold little size can draw for themselves a lot of useful experience in building their networks. Frankincense, the information center network technology market is undergoing a transmutation process thanks to new architectures, technologies and products, which, in particular, are aimed at resolution the following problems:

• Meliorate and simplify network operations to better forgather business goals and greater data kernel flexibleness by using new, auspicious APIs, increasing programming and meshwork mechanization capabilities;
• Take into score changes in size and density in data centers;
• Allow changes in the body structure of application traffic;
• Provide solutions that are hospitable and similar to increase interoperability, foster innovation and reduce vendor-taxon connectivity.

The primal building blocks of a data center network admit hardware and software that rear glucinium acquired together OR independently.

Hardware

The hardware relevant includes meshing switches to which servers and other infrastructure elements are connected. With the exception of VMware, all vendors covered by this study sell computer hardware switches. Currently, we are perceptive that for the normal operation of most spic-and-span information centers, access to a server on 10 Gbit Ethernet (GbE) peripherals and 40GbE trunk is required. In addition to the most plumping-scale data centers, we have not yet found significant demand for access to the server on 25GbE, 40GbE operating theatre 50GbE or 100GbE backbones. In addition, new interfaces appear on 25GbE and 50GbE, simply generally the demand for them has not yet formed. The main type of physical network topographic anatomy for about typical data centers includes a combined- or 2-level leaf / trunk switching architecture and is made in the shape of a ready-made Ethernet fiber. Additionally, all but switch manufacturers presently use highly-developed Si in their hardware kits. Thus, although the difference in computer hardware still exists, the main specialization is shifting toward software.

Software

All manufacturers covered aside this study produce data center software at various levels. Traditional software for data center networks came in combination with (a) computer hardware and (b) an administrative (that is, a working) interface. Although this traditional approach to data center networks is still wide used to this twenty-four hours, software is at the center of transformational change. New technologies (such as software-defined networks or SDN, disaggregation by means of Ethernet fibers and switching) allow the development of software-circumscribed traffic routing solutions regardless of and / or individually from the ironware and working interfaces.

Regardless of whether traditional operating theatre current approaches are used, nam software components of a distinctive corporate data center network admit:

• switch operating system (Osmium): operative system software package that runs along individual physical network switches;
• virtual switch: realistic switching software that runs on physical servers functioning hypervisors and virtual machines;
• management software: network management software used to manage network infrastructure;
• restrainer: centralized computer software that implements a degree of control and insurance policy management that can represent programmatically accessible through external systems.

In some data center network, leastwise 1 of these components is mandatory, simply not all. For example, in some non-virtualized data center virtual switches are not needed. In improver, these components can be purchased together (from one supplier) or separately. This creates a certain kinetics in the commercialise, where the suppliers blanketed by this hit the books whitethorn chuck out to be both competitors and partners, depending on the type of network surgery.

What changed?

Supplier Acquisitions

Two notable acquisitions occurred during 2014. Ordinal, Lenovo noninheritable the portfolio of the x86 server and the IBM information centre switching. Secondly, China Huaxin acquired a controlling interest of 85% of the investiture in the corporate line of work of ALE (formerly Alcatel-Bright Enterprise).

Software Difference

Ended the past 12 months, manufacturers have continued to use developed silicon based designs in their switch designs. But additionally there is a tangible strategy in the direction of SDN. Thus, the distinction 'tween manufacturers' solutions continues to shift toward software system (including management, resourcefulness allocation, automation, and orchestration) with increasingly standardized computer hardware capabilities (such as bandwidth, power, and scalability).

In the chivalric 18 months, according to Gartner surveys, data center customers many often consult to the concepts of virtualization, control, and orchestration than "speeds, channels, and protocols," which has dominated for many years.

SDN is comme il faut increasingly interesting

Many of the providers included in that "magic quadrant" have ready-made fundamental strides in fulfilling their network strategy (SDN). From the user's point of view, 2014 was the year of the come out of a cagy exam of SDN equally the mainstream market clause as the market went beyond its "computer architecture" as defined in 2013. Demand incidental SDN magnified in two surgery trio times in 2014, mainly overdue to customers difficult to test SDN solutions. Interest in these SDN technologies is currently shown by both Case A and Type B clients (find note 1), which often refer to the chase incentives that prompted them to try SDN and related technologies:

• fast system to work;
• increased level of certificate;
• extended range of controls;
• attenuate network computer hardware / software costs;
• depress operating costs;
• reduction of dependency on one supplier;
• caution regarding hourlong-term investments deprived of SDN capabilities.

According to Gartner, there are currently approximately 1,000 enterprise-order data centers that implement mainstream SDN solutions, which is nigh three times more than a class ago. In the past year lone, Gartner has accepted over 250 SDN requests, including over 50 for comparisons 'tween VMware NSX and Cisco ACI.

SDN Overlays

Some manufacturers included in this Magic Right angle provide the power to sheathing networks by creating virtual networks on top of the physical network. Much solutions, as a rule, combine the capabilities of network and computing resources to provide a more flexible infrastructure. Although this in itself is grave sufficient, it is equally most-valuable to consider how the various overlay methods are implemented. The overlay is still completely dependent on the substratum physical network, and meshing control and visibility issues are crucial to ensure the reliability of the overlay. There are prospects for improving the coordination of SDN overlay with the somatic network. This creates absorbing dynamics in the market, because overlay manufacturers nates again turn as partners and competitors of traditional suppliers of network switches.

Disaggregated switches (white boxes)

The matter to in and use of disaggregated switches has enlarged significantly in large-scale leaf data centers over the past few quarters. Disaggregated switches are variable, cook-to-wont platforms supplied by Original Contrive Manufacturers (ODMs). Buyers of the white box should buy up and integrate their own reading of web software for these platforms. This eccentric of permutation currently accounts for more than 5% of all data center ports oversubscribed, and there is an increased rate of market ontogenesis. Inspired away large-scale structures, an increasing number of Type A organizations are showing interest group in disaggregated switches.

This led to the outgrowth of a new style of switches, which Gartner calls branded Edward White boxes or "bright boxes" (Brand + White = Brite Box). In switches of this type, hardware is disaggregated from software program, but measures deliver been purloined against some of the shortcomings of a "clean" disaggregated switch, such Eastern Samoa acquisition, integration, and affirm. The surroundings for this mode of switch is just protrusive to emerge. For example:

- Dell supports the operative networks of operating networks from Cumulus Networks and Big Switch Networks on its equipment;
- Juniper Networks supports "bright boxes" based along disaggregated switches that run on an optimized version of Junos software system;
- HP recently declared the release of a "bright-box" type of solution with white-box hardware and Cumulus software;
- New vendors such as Big Switch and Pica8 declare oneself OSs for switches that john be keep going best of disaggregated switches;
- A Facebook project known as the Facebook Open Compute Project (OCP) Hacek offers a reference platform for soul-development of commercial solutions.

Over the succeeding 12 months, many more examples of these business models and commercial memory access partnership options are expected.

Acceptant networks

Vendors who accompaniment a more open approach to SDN have responded to the market challenge past raising support for OpenDaylight (ODL) equally their platform. While almost completely of the manufacturers therein examine are members of the OpenDaylight consortium, many importantly, many of them released flagship SDN products based on OpenDaylight code, including Avaya, Brocade, and Extreme Networks. Broad corroborate for OpenDaylight provides the opportunity for a third environment to appear on the SDN commercialize, which will stimulate new innovations, the development of functions and operative environments (the current market pose and influence in the information center diligence will allow Cisco and VMware to found more blinking environments).

Converged Infrastructure / Integrated Systems

While virtually SDN-based solutions offer a inaccurate range of disaggregation options, we see the opposite trend in one market segment, and this trend is characterised by the offer of nonsegregated systems. Where the challenge is to simplify operations and optimize frame-up time, converged infrastructures are gaining in popularity. Death year, converged infrastructures accounted for 7% of the data center infrastructure market (which includes the meshwork, servers, storehouse systems and associated management components) with an yearbook growth of 57%. The consequences of using these technologies are that they are largely strictly prescribed, which leads to the transfer of the physical admittance level of the purchased network from an solely network variation to the server / storage system / network option.

What is required from network technologies for new data centers?

The surround was described supra, which has undergone significant changes and makes IT possible to get in the market with the most different, Thomas More lively and effective offers of network technologies.

Numerous of the providers covered in this study provide "good" solutions to encounter the current current requirements for data centerfield networks. However, there are enough differences 'tween suppliers, including in terms of toll, architecture, you bet suppliers work out the issue of meeting new and future requirements. Looking into the later, modern data center network solutions must meet the following requirements:

- The need for simplified and automated network architectures;
- Increased meshing flexibility;
- Exchange the size and density of the information center network;
- Changing the architecture of applications;
- Invention and diversity of options;
- Migration of intellectual capital and its protection;

Easy networks with increased flexibility

Information center networks must forgather the growing business needs for quicker, service-oriented IT tasks. This is driven by occurrent business requirements and the availability of more flexible options within and outside traditional corporate IT. These options (often they are based on essential and cloud platforms) have identified non-optimal paradigms of network operations (including static and manual configuration and configuration procedures) that increase the time for delivery of services, reduce the level of web availability, increase operating costs and significantly complicate the scaling of the working Wednesday.

Resize and Density

The size and denseness of information centers are changing, with several main trends that have both enlargement and reduction of data centers:

- The server and data inwardness consolidation requires IT organizations to centralize calculation resources and deoxidise the number of physical data centers, resulting in few, but larger, enterprise data centers.
- Increasing the density of computing using multi-core multisocket servers, combined with virtualization and storage convergence, is to reduce the physical footprint compulsory. The loads that are used to capture multiple server racks are currently delivered in parts of the same rack.
- Migrating applications to external cloud services also reduces the space requirements inside the incarnate data eye.

Changing Application Architecture

The typical go-ahead-pull dow applications that are now the just about public are progressively independent of unique servers and allow for sevenfold deployment options. In addition, other applications, such equally big data management systems, have more stringent bandwidth, latency, and port buffer requirements than tralatitious applications. As a result, there is an increasing need to effectively do traffic within the information center (east-west) recently led to the emergence of several innovations:

- High-performance, top-of-rack (ToR) switches with low latency;
- The growth of a one- or 2-point corporeal switch architecture;
- The growing use of central switches with a fixed form factor;
- Higher level of traffic promotion and better intellectual support at the waiter access level (victimisation realistic chassis or cluster system chassis).

These approaches step-up server-to-server productivity and allow developing data center network technologies in the direction of a uniform set of capabilities for totally connected computing resources.

Long Foundation and Options

Disaggregation, SDN and open networks furnish an opportunity for transformational changes in the market for network solutions. The decoupling of hardware and software and the separation of control and information transmission levels map the potential for fundamental improvements in the design of networks, their acquisition, management and deployment. These improvements give up the establish of third-party applications on new web solutions with the latent to significantly blow up their spectrum in the semipermanent innovation perspective. This innovation - combined with open net, disaggregation and / or SDN - is clearly a disruptive market vogue for all that has traditionally been seen as a deep integrated, hardware-oriented model.

Transportation and protection of information capital

Given that new technologies and business models are critical, manufacturers should also equal related to about providing information security department tools for existing data and their conceived migration migration from currently deployed architectures to new ones.

The Magic Quadrant

Figure 1. The Magic Quadrant for Information Center Networks

Strengths and weaknesses and suppliers

Arista networks

Arista, aside far, is one of the fastest growing manufacturers noted in this Magic Quadrant. Now it is firmly in tertiary place in the ranking of data center networks, given the market share of revenue involvement shown by Gartner customers. Arista delivers a unopen physical network solution that bathroom be integrated into any data shopping mall network architecture. Arista provides a simple product computer architecture that scales from smaller to very large data centers. The vendor has invested in its Extensible OS (EOS) software to make up features for lightweight meshwork and application deployment. Arista is in the process of expanding her target customer place from the level of early, technically prudent buyers to the level of enterprises of a wider circle of conformists, and geographically expanding beyond North America and Europe. Arista has traditionally been a leader in terms of the price / performance of the data centre network, but the growth in the use of atomic number 14-settled switches and the aggressive pricing of competitors is quickly closing the gap. Organizations should consider Arista's proposals for any data kernel, provided that the supplier has regional certification and provides engineering support for the solutions in interrogative sentence.

Strengths

- Arista provides late integration of her products with a variety of software and SDN instrumentation solutions, which gives customers the exemption to take without locking to whatever one architecture.
"Arista built a flexible software environment (Arista EOS) with powerful features that include network telemetry and application profile with extensible APIs.
- Arista offers solutions that are optimally configured for the environment and that drive reward of the various Arista form factors, which helps make a more efficient and oft cost-effective structure.
- Arista offers superior solutions with deep buffering and blue latency, which allows you to meet the complexities of modern data center applications.

Weaknesses

- Geographic coverage is still small in Asia, the Pacific, and emerging markets compared to more established sellers, and so far Arista is only stepping aweigh its national technology and carry programs to major meet the needs of the main market.
- Arista does non support converged storage systems and information networks for which FC (or FCoE) is a required requirement.
"Despite the fact that the Arista meshwork solution is a same compromising and reliable foundation of the meshwork, organizations that need dynamic orchestration systems will require to desegregate IT into an external orchestration system.
- Recent legal issues with Cisco demonstrate an increased level of perceived risk for much potential customers. Organizations should instruct their effectual departments to assess the risk associated with this issue (see note 2).

Avaya

Avaya is unrivalled of the smallest players in that magic quadrant when it is estimated settled on on-line revenues (currently less than 1% of revenue from data centers), although it still has a large unfluctuating base of orthodox solutions. Avaya's current solution — based on its Cloth Link up architecture — is a highly automatic resolution that provides prosperous expandability inside and 'tween data centers for the mobility of a easy virtual machine (VM) and optimized east-west traffic flows. Until recently, Avaya data center solutions lacked significant investments to enter the market (in sales, systems engineering and marketing), which significantly limited its ability to play on the market and subdued growth.

Strengths

- Avaya offers a highly machine-driven solution that includes high-performance multicast capabilities that are less demanding on configuration and administrator intervention than competing solutions.
"Based on client feedback and end-user appraise results, Avaya is systematically rated higher up norm in how its budget solutions meet customer expectations and requirements.
"Avaya has tried itself in delivering flooding-resiliency data shopping mall net architectures.
"Avaya's Fabric Connect solution enables ordered expansion between the information center and from the channelise office to branch offices, giving a easy enterprise web solution.

Weaknesses

- Avaya is currently one of the smallest sellers in this sorcerous right angle for tax income for data centers and has a limited (although growing) amount of allocated resources for mesh technologies.
- Provider channels may not Be ample, therefore, enterprises moldiness have their own qualified resources to reenforcement new implementations.
- Avaya started yield of SDN-settled products ripe, entering the 1H15 market with SDN Fx computer architecture.
- The automated structure of the Avaya data center is based on the Shortest Path Bridging (SPB) protocol, which is poorly represented by other vendors. This can tether to integration issues in multi-vendor environments.

Brocade

Brocade's data center networking solution is supported its VCS automated body structure technology and Vyatta SDN controllers. Brocade has a long and productive data center provider account thanks to its market-leading SAN solutions. The company is a drawing card in converged networking and storage. Its VCS geophysics architecture, supported by a set of VDX switches, provides a high level of on-dining table structure automation and can be combined with a high level of routing for conjunctive data centers and outside resources. Brocade is a leading initiator of the OpenDaylight SDN and a notable proponent of the open SDN environment. Consider Brocade when you require an machine-driven data center network social structure.

Strengths

- The supplier provides an automated structure with a configuration that does non postulate special constellation ("zero-touch on") the purpose of which is to facilitate in the first deployment and expansion of the social organisation.
"Brocade is a major player in ODL and is growing investments and innovations in Vyatta's ODL-based SDN controller software, and also has a number of software options for network function virtualization (NFV), helping to develop an open SDN environment.
- Brocade offers a subscription-based purchase option, which may be useful for the stage business case for new investments and makes information technology possible to switch to a new technology without capital expenditures.
- Brocade provides reliable integration with OpenStack and VMware (vCenter, vRealize and NSX), including a hardware bridge for NSX-MH.

Weaknesses

- Gartner respondents report that Brocade solutions are among the just about overpriced offers compared to competitors. However, late additions to the VDx portfolio should allow Brocade to offer more competitive pricing options.
- Brocade service channels are not established or non wide enough in comparison with a momentous number of leading competitors.
- Brocade does not offer its own converged data center infrastructures. However, its technologies are integrated into other converged solutions so much as EMC VSPEX and VSPEX Blue, Hitachi Unified Compute Chopine (embedded and ToR) and Fujitsu vShape.
- According to the customer survey and the survey results, there are problems with the quality of the code.

Cisco

Lake herring among corporate electronic network specialists has long been considered a "safe choice" and stiff the leader in the global market away a wide-cut margin, judging by the dollar volume and gross. Cisco is now undergoing serious tests, trying to maintain its large fleet of installed equipment, while maintaining yard in a rapidly changing market. Cisco has a deep and wide range of solutions that tin can meet all the requirements for data center networks, from small to medium-sized organizations (SMBs) to large enterprises and providers. Withal, there are some overlays, contradictions in the expression of architectures. Gartner respondents complained about puzzling options that could lead to choosing the wrong product. Last year, Lake herring continued to bring forward its flagship information center solution, and now supplies software and hardware for Application Centric Infrastructure (ACI). ACI is a programmable Ethernet framing that supports a centralised, policy-based model as an alternative to the traditional, device-centric command-line interface (CLI) come near. Cisco should follow considered for any information center network pick globally.

Strengths

- Lake herring has the largest stable understructur compared to any trafficker therein Thaumaturgy Quadrant. In that respect volition always beryllium a large number of specialists in the endeavor who are well acquainted with its products and solutions.
"Cisco networking products are embedded in several integrated arrangement offerings, including VCE Vblock, NetApp FlexPod, and IBM VersaStack, with which organizations can quickly build infrastructure.
- Cisco offers several products with which organizations can combine logical and sensual substructure: vSwitches, supported by VMware, Microsoft hypervisors, Xen, KVM and Linux containers, also as blade switches that can be utilised in Dell, Lenovo and vane chassis HP
"In addition to networking technologies, Cisco provides computing, network protection, repositing, and security and Interconnected Communications (UC) solutions that are suitable for customers who do not want to buy from three-fold vendors.

Weaknesses

- Supported respondent reviews and contract reviews, Gartner considers Cisco solutions to be among the most expensive on the grocery, symmetrical when compared to competitive offers. In addition, Cisco and its distributors often come crossways technically cosmopolitan solutions.
- Cisco has a story of creating products that are based on obstructed and / or trademarked elements, which leads to dependence on a single supplier.
- The Cisco ACI platform provides narrow data protection for the existing fleet of installed equipment on Nexus and Accelerator equipment surgery for the Cisco UCS waiter architecture. There is currently a lack of features, much as FCoE reenforcement and external information center interconnections, used by many organizations.
"Although Cisco ACI is now in stock everywhere, there is very limited acceptance of this product on the market: less than 25 ACI industrial installations in large-plate enterprises by the end of March 2015. Corporate customers continue to report that Cisco is struggling with industrial-grade ACI setup.

Dingle

In the field of network technologies, Dell's information center is one of the top four players in damage of supply, and its revenue o'er the past year has grownup supra the average market. There are currently many than 24,000 Dingle Networking customers. The provider offers a homogeneous roll of taped, chassis and blade switches that meet the needs of nigh enterprises. Dell focuses primarily connected customers with Dell servers or computers and has a strong market position for moderate-sized businesses. At the close of 2013, Dingle realized corporate privatization in order to achieve financial tractability in the process of transforming its operations. Arsenic a result of all this, Dell is the supplier with the largest number of innovations and breakthrough achievements in the field of data center net technologies in the marketplace over the ult 12 months. In January 2014, Dell announced support for a au fon new shift substitution class (disaggregation), which allows organizations to run network software from other people's OS networks on specific Dell hardware. This caused unrest in the whole network industry and forced other manufacturers to consider and / or respond with similar competitive offers. Organizations with an existing relationship with Dingle whitethorn study this provider, as well as humongous organizations that need an open network solution. This caused unrest in the entire meshing industry and forced opposite manufacturers to believe and / or react with similar competing offers. Organizations with an existing relationship with Dell whitethorn consider this provider, Eastern Samoa wellspring as large organizations that postulate an explicit electronic network solution. This caused unrest in the entire network industry and forced other manufacturers to consider and / Beaver State reply with similar competitive offers. Organizations with an alive relationship with Dell may consider this provider, as well A largish organizations that need an open network solution.

Strengths

- Dell has developed one of the nigh ingenuous, invariant, and standardized approaches to meet client data center requirements.
"In addition to networking, Dell provides protocol controllers, computing and storage infrastructure, which is convenient for customers WHO favor to buy infrastructure from a single vendor.
- Dell has integrated its network components into integrated systems from Microsoft and (Microsoft Cloud Platform Solution [MCPS]) and VMware (EVO), which is salutary for customers who prefer a quickly infrastructure deployment.
- Dell is the No. 3 supplier in the 40GbE port business after Lake herring and Arista Networks, and this is a key requirement for superior data centers.

Weaknesses

- Gartner respondents study stableness issues with Dell network software in some specific use cases.
- The vendor has a limited outlook outside of Dell's current affairs and is therefore seldom mentioned in customer lists for environments that come not use other Dell products.
- Despite the presence of many innovations, support for detailed (disaggregated) switching models for Dingle is still a novelty, and according to Gartner, there are less than 100 of them in March 2015, if we blab ou nearly the raze of yield enterprises.
- Dell traditionally supplies products with a direct sales mannequin, so IT has underdeveloped statistical distribution channels compared to different suppliers. When working with Dingle partners, before making a deal, you should make over inquiries and make sure that they have several implementations of the befitting scale of measurement.

Extreme networks

Extreme has completed the assimilation of Enterasys Networks and now has more 14,000 corporate customers. In the Extreme data center manufacture, AMONG the smaller suppliers, covering about 2% of the market (when measured by tax revenue or turnover), and it is non often institute in the lists of competitive alternatives considered aside respondents. Over the class that has passed since the skill of Enterasys, the company focused connected streamlining its assortment, updating distribution channels and affiliate programs in order to improve support for customers interested in data center network technologies. To boot, the ship's company released several new hardware switches and its own SDN controller, an enhanced version of OpenDaylight. Extreme products are worth considering for businesses in the Americas and Europe,

Strengths

- Gartner respondents praise a very well-knit level of customer service, which is too confirmed in research surveys.
- Extreme has a deep and all-encompassing range of network equipment for information centers with to a greater extent than 15 years of provision high-performance and honest network solutions.
- Extreme has an aggressive pricing insurance on competitory terms.
- Uttermost has an assimilative and high-standards approach to meeting new information center network requirements, which includes extensive OpenFlow support, an OpenDaylight-supported SDN controller and multi-API support, including the Network Configuration Protocol (NETCONF).

Weaknesses

- Extreme is nonpareil of the smallest Peter Sellers among those covered in this study and is growing at a pace under the market average. Thus, when buying, organizations must make sure that there is a sales and overhaul complex body part at the local level.
"Once Extreme cooperation with Lenovo in the athletic field of integrated systems seemed bright. Now this imag is in doubt due to Lenovo's acquisition of IBM's portfolio of networking solutions. Before choosing a joint Extreme / Lenovo project, you should carefully study their joint plans for further cooperation.
- For those who are looking for a converged network solution for a storage waiter, Extreme is not suitable, because it focuses on networks in its development.
- Although this vender offers high-operation solutions that allow the requirements of large-ordered series environments, the stream Immoderate offerings miss some features that many large and "peculiarly precocious" organizations may need: integration with VMware NSX, reenforcement for Puppet and Chef.

Horsepower

HP is the No. 2 player in the data center network technology market, it has a global scurf, although during 2014 its growth did not keep pace with the market rate of growth. HP has a ample range of fixed, build and blade switches to meet the needs of all corporal organizations. Nonetheless, Gartner respondents report problems with overlapping solutions that could put option HP ware learning into question. Competing offerings of blade switches (6125XLG and Essential Connect) pass unmanageable to sell integrated HP systems and earn HP Networking harder to take a result. HP is a strong believer in open SDNs and architectures with disaggregated switches with good device and controller support in conjunction with the purchased SDN App Shop.

Strengths

- HP takes a selfsame broad and standardized approach to meet a wide range of customer requirements. This is confirmed by Gartner studies, according to which the company was rated as the most open supplier among those covered by this depth psychology.
- HP's Comware software provides patronize for advanced Layer 3 features, FCoE, structures and SDN environments at one common price, with a common hardware range.
- Hewlett offers a stark set of converged infrastructure with a electronic network, computer science and storage functions, with management via ONEView HP.
- HP still uses its own controller (as of Crataegus oxycantha 2015), however, the company has committed to support the OpenDaylight scheme, as it becomes scalable and reliable, and adapt its SDN App Store to run in OpenDaylight-settled solutions.

Weaknesses

- Gartner respondents often report that, disdain their global reach, Hewlett's distribution channels are non as strong as expected for networking products.
- Gartner respondents may be puzzled by conflicting products based on server and net sword switches. The lack of desegregation of Horsepower Practical Connect blade switches in the HP Networking ironware and software architectures has LED some organizations to take on alternative solutions with closer integration between network and computing capabilities.
- HP and its channels sometimes underrating the support system, which can lead to service problems for some customers.
- Hewlett's support for numerous SDN options, including Helion OpenStack with Essential Defile Networking, VMware NSX, its own HP Splashed Befog Networking (DCN; supported along Alcatel-Lucent Nuage Networks) and HP Networking Virtual Application Networks (VAN), can movement the customer confusion.

Huawei

Huawei continues to expand its mountain range of enterprise data center networks and, as a relatively newborn newbie, is fit to offer flexible options. Huawei Taint Fabric architecture, CloudEngine switching platforms and SDN controller are based on open standards aligned to strengthen open SDN innovation in the market. Huawei made momentous strides in 2014 in the supply of its SDNs and continues to be an astir participant in engineering working groups and standards developing bodies, including OpenStack, OpenDaylight, and Networking Foundation Open (ONF). With global reach and scope, the company's data shopping center products are primarily delivered in China, Asia, the Pacific, and some other emerging markets. Huawei should be considered past buyers in Asia and emerging markets, especially

Strengths

- Huawei has a wide range of switches for information centers, which is settled on its CloudEngine, which includes scalable chassis architectures and switches with a fixed form factor (FFF) of the riffle-trunk type.
"Huawei has a wide mountain range of open SDN options, making IT possible to deliver software overlays, complete infrastructures and SDN hybrid solutions — all based happening standards in order to support integration of third-party extensions and improvements to its personal architecture.
- Huawei offers a complete solution for converged data middle-of-the-road infrastructure, including electronic network, computing power and storage.

Weaknesses

- Outside of China, Huawei seldom appears on customer lists. Huawei has limited (albeit growing) sales and dispersion channels in North America and Northwestern Europe.
- Spell Huawei is obviously global in scope, its capabilities and sentience are small in relation to some markets due to political issues, rising barriers and East-Western competition.
- Gartner respondents allege that Huawei needs to improve sales processes and the quality of documentation.
- Huawei has a relatively poor marketing mesh and data system - this does not allow it to increase visibleness and differentiation. This means that the company does non expend all voltage opportunities in its target markets and regions.

Juniper Networks

Juniper bush has an extensive and wide of the mark range of capabilities in the developing of network solutions for data centers and is one of the primary suppliers in the top foursome in revenue and turnover. However, Juniper has lost market set over the past 12 months and is now lagging rear Cisco, Arista and HP at the call for of curious customers. Genista raetam's marketing report during 2014 baffled many traditional enterprise-level customers. Raetam now has more 5,000 customers with its MetaFabric, an umbrella architecture that spans its information center portfolio of Letter x and QFX switches, Contrail SDN software, QFabric Ethernet data center routing fabric, and security. Organizations with large data center networks should take Juniper into account.

Strengths

- Juniper has extensive undergo supporting medium and large-sized data centers with increased requirements for some enterprises and service providers.
- Juniper has an open and well-premeditated political program to meet the new requirements for data center networks.
- In tenders, reported to Gartner, Juniper aggressively mopes.
- Juniper bush offers an open and compatible architecture, including the Open API, Bright Box switches, and provides support for disaggregated switches and open up source SDN controllers.

Weaknesses

- Gartner respondents report instances of computer software instability on the EX9200 switching platform, and there has been a decrease in customer satisfaction and support (at least in part cod to the transition to the new reinforcement arrangement).
- More Gartner respondents note the confusion with the many Juniper bush data kernel switching options that can lead to problems when choosing a cartesian product.
"Juniper's long-term commitment to support core data center network environments is a headache for conflicting messages throughout 2014.
- Although Genista raetam has of late launched its Contrail cloud "stack", which includes computing power and storage, it still remains primarily specialized in networks and security measur, and this limits its grocery store to those buyers who deficiency an independent mesh bed.

Lenovo

Lenovo is a hot member in this Magic Quadrant. He was brought here thanks to his recent acquisition of IBM's x86 server enterprise and its associated set out of blades and servers. IBM centered exclusively on data center access and did little to create a more complete final stage-to-end result to the data center network structure. However, Lenovo has seen a resurgence in innovation and a marked intention to offer more self-contained converged infrastructure solutions. Lenovo's strategy is to use a silicon-based structural solution to provide data center networking solutions that can support more 2,000 host ports in a fully zero-pinch structure configuration.

Strengths

- Lenovo has extensive feel for in the field of data center servers, which can be used to expand the range of net solutions.
- Lenovo offers an automated social structure solution that simplifies deployment.
"Lenovo has a serious curriculum to develop a more complete data center solution using open and exchangeable architectures."
- Lenovo specialists have experience in bringing sunrise technologies to the market. The company was one of the first to start selling top-of-rack 10GbE switches and released software for the first VMware products.

Weaknesses

- Lenovo has restricted competence and data center capabilities beyond what is snow-covered aside x86 servers.
"Lenovo has traditionally focused only connected the server access layer and has limited experience in designing and deploying convoluted net information center solutions.
- Lenovo does not offer chassis-founded products for specially hulking enterprise environments.
- Current customers should occupy about the continuity of the support system in connection with the transition from IBM to Lenovo.

VMware

VMware delivers virtual switches and SDN overlay systems for virtualized data centers. VMware has a great shape in the data shopping centre industry due to its near-official leadership in the virtualization market. As a result, NSX, an SDN overlayer product, is causing a high degree of interest on the component of VMware customers. Over the past year, VMware has centralised on promoting NSX, preparing global implementation channels and highlighting specific usage scenarios, much as security within the data center (microsegmentation) and mortal-provisioning. VMware currently has the largest fleet of installed hardware with any SDN pick happening the market. VMware is the lonesome vendor draped in this study that does not sell hardware, ascribable which its clients must develop, establish and bring off the physical network infrastructures of the data center separately. This puts VMware in a unique position, because it is likewise a partner who works with many suppliers in this grocery and is their competitor in the field of software elements in the data center industry. VMware should constitute considered as an option for organizations seeking to increase network flexibility or security in a data center with a high level of virtualization, if the main supplier of the hypervisor is not Microsoft. and is their competitor in the field of software elements in the data shopping centre industry. VMware should beryllium considered as an option for organizations seeking to increment meshwork flexibleness or surety in a information center with a high level of virtualization, if the independent supplier of the hypervisor is not Microsoft. and is their contender in the field of software elements in the information rivet industry. VMware should be considered as an option for organizations seeking to increase web tractableness or security in a data center with a high level of virtualization, if the main provider of the hypervisor is not Microsoft.

Strengths

- VMware's virtual-switching solutions are widely distributed passim the fade of installed VMware computer hardware with a widely range of features and a proven record of reliability.
"Thanks to its pricing model, NSX VMware allows organizations to gradually enforce SDN without the need for large upfront investments."
- VMware NSX can keep going top of any appropriately prepared IP-supported Ethernet network.
- NSX microsegmentation is an advanced mechanism that provides security within the data center (east-west) in a be-effective mode compared to traditional instrumental approaches.

Weaknesses

- NSX has declined sharply in environments running Microsoft Hyper-V (presently not braced by NSX) and / or which are not highly virtualized. In addition, VMware NSX comes in two versions - NSX for Vsphere (NSX-V), which has a tasty set of network functions based on VMware's Vsphere Far-flung Switch (VDS), and NSX for Multi-Hypervisor (NSX-MH), which relies on on Open Virtual Switch (OVS). NSX-V has tighter integration with sister systems, a healthier level of security and integration with Vsphere. NSX-MH relies on integrating with OpenStack.
- There is limited visibility between the virtual overlay of NSX and fleshly networks, which can affect the overall visibility of the network and increase the fourth dimension for troubleshooting and repair.
- There is a very limited number of deep-scale deployments (with much than 10,000 virtual machines) of NSX for the Vsphere reading, so in large data centers you should with kid gloves weigh current VMware capabilities and deployment experience.
- VMware is a newcomer to the net business with immature distribution channels and a sales network, which could adversely affect deployment. Underway customers rate VMware rock-bottom in terms of network integration and support capabilities. Organizations must ensure that their local support teams guarantee various implementations of this order of magnitude ahead qualification a decisive purchase.

New and inactive suppliers

Explore criteria such as Magic Quadrants and MarketScopes are regularly reviewed and refined as markets variety. As a result of these adjustments, the fixed of suppliers in some Wizard Quadrant or MarketScope may switch time. Changing the supplier's put together in the Legerdemain Right angle or Marketscope from year to year does non necessarily mean that Gartner has changed his psyche about this supplier. A change in the rating criteria may be a reflection of changes in the market or be the result of a change in the specialization of the provider.

The data center network market is extremely energising and innovative, as manufacturers are constantly difficult to bring new ideas and solutions for the enterprise level into it. Some manufacturers that do not still meet the criteria for inclusion body in the surveys are still monitored aside Gartner, since they possess the potential to influence this market in the long term and may follow of interest as flyspeck, progressive suppliers. Vendors actively tracked at this grade include ALE Enterprisingness (formerly Alcatel-Lambent Enterprise), Alcatel-Lucent Nuage, Allied Telesis, Big Switch Networks, Cumulus Networks, D-Link, Mellanox Technologies, Microsoft, Midokura, NEC, Netgear, Oracle , Pica8, Pluribus Networks, Plexxi, Quanta Computer, and PLUMgrid.

New

- Lenovo was added to the Magic Quadrant callable to its acquisition of an x86 server from IBM and related data center network technologies.

Eliminated

- ALE (erstwhile Alcatel-Lucent Enterprise) dropped away because IT does not meet the income criteria.
- IBM is not being advised as a result of the sales agreement of its meshing equipment assets to Lenovo's data center.
