Data center rack server market forecasted to $40.25B by 2019 December 2, 2014     Email       Print   1     Facebook   3     Twitter   0     LinkedIn   4     Share         A new report from MarketsandMarkets (Dallas, TX) analyzes market dynamics, future roadmaps and global trends, and also provides competitive intelligence and forecasts over the next five years, for the data center rack server market. The research firm's analysts expect "an increasing adoption of power efficient and low-cost, high performance computing solutions, as major vendors are seen aggressively investing and rigorously working toward building cost-effective data center solutions, in an effort to reduce the overall cost incurred by end-users."MarketsandMarkets forecasts the data center rack server market to grow from $22.01 billion in 2014 to $40.25 billion by 2019, at a compound annual growth rate (CAGR) of 7.17%. North America (NA) is expected to be the largest region for the market's growth in terms of revenues generated, but Asia-Pacific (APAC) is also expected to emerge as a high-growth market. According to the analyst, in the market's current scenario, the data center rack server has significantly impacted the global data center market and is expected to experience exponential growth in the coming years. The future adoption of data center rack server is expected to be in heterogeneous environments and hybrid clouds, with more focus on software-defined storage.As defined by the analyst, a data center rack server device is defined by a controller which gets deployed on independent hardware platforms and hypervisors, and eliminates the dependency on traditional hardware platforms, notes the analyst. This helps organizations to control data access and storage, thus reduces associated costs, and improves efficiency and scalability. Data center rack servers are also a major component in the data center market. The newest platforms are run by software-defined controllers, adds the firm, which reside on a data center's servers, specifically to serve large and heavy applications and data flow such as hosting, cloud, or large-scale applications. SDN controllers enable multiple virtual servers to run on a single physical server; all the virtual machines are isolated from each other and are decoupled with the help of hypervisors. SDN controllers also enable live migration and helps the organizations into virtual computing. These software-defined rack servers help the organizations to cut energy costs, increase efficiency, agility, and performance, thus reducing complexity and space required for servers."The adoption of a rack server based data center will play a vital role in helping IT teams meet the fast-evolving business needs of their organization," states a press release from MarketsandMarkets announcing the new report. "In today's business era, it's become important for enterprises and businesses to maximize IT performance, but also on controlling costs by reducing cooling requirements, and power consumptions along with simplifying management of resources and data. To meet these objectives, companies are designing rack server in such a way to provide high performance, energy efficiency, optimize hardware resources and simplified management."The new research report from MarketsandMarket, Data Center Rack Server Market by Data Center Type (Tier 1, Tier 2, Tier 3, Tier 4), by Services (Consulting, Installation and Support, Professional), by End User (Mid-Size, Enterprises, Large) - Global Forecast to 2019 is now available https://www.raycom.tw/hot_120743.html Data center rack server market forecasted to $40.25B by 2019 2025-05-20 2026-05-20

Datacenters Drive 25GE Effort

Ethernet group includes Google, M'soft

Rick Merritt

7/3/2014 09:40 AM EDT 

LONDON – A group of five vendors will define specifications for 25 and 50 Gbit/second Ethernet in a move that, if successful, will demonstrate the power of large datacenters to drive technology. The effort also could accelerate adoption of two related technologies -- 100G Ethernet and silicon photonics.

Arista, Broadcom, Google, Microsoft, and Mellanox say they formed the 25G Ethernet Consortium to accelerate development of the speed grades to connect rack-mounted servers to top-of-rack (TOR) switches. They suggest big datacenters at Google and Microsoft are ready to move from using 1 and 10G links on individual servers to the new 25 and 50G speeds while the TOR switches upgrade from 10 or 40 to 100G.

Earlier this year three separate groups proposed 100 Gbit/s interfaces, mainly aimed at an emerging class of fast links for data center switches.

Google alone is said to have more than a million servers in its global datacenters. The big web server sites are now said to represent as much as 20% of all server sales, market watchers say.

Missing from the consortium are several other large, competing datacenter operators such as Amazon and Facebook. Also absent are other large networking chip and systems vendors such as Cisco, Intel, and Marvell.

The IEEE 802.3 group that traditionally defines Ethernet standards considered working on the 25 and 50G speed grades after a close non-binding vote in a March meeting. The group is now revisiting that decision.

In a straw poll at the March IEEE meeting, 30 engineers voted to start a 25G standards effort with 27 voting against and 21 abstaining. A total of 25 said their companies would support such an effort. The "consensus [was] not overwhelming," according to public minutes from the meeting, so a Microsoft datacenter manager who raised the issue declined to make a formal motion to start a 25G effort.

The consortium has not publicly released a specification, but comments from its members and analysts suggest its technology will be straightforward. It is expected to use components now coming on to the market supporting 25G serial lanes -- at least some of them geared to use with silicon photonics.

"25G and 50G Ethernet can leverage 100G QSFP28 breakout similar to how 10GbE is currently broken out from 40GbE using QSFP+," said Rochan Sankar, a product marketing director from Broadcom, in an email exchange with EE Times. "The 25G Ethernet specification requires a single 25Gbits/s serdes lane and associated PCS/MAC to be implemented in silicon -- which is simply a quarter of the serdes lanes used to support 100GE port over four lanes," he said.

"The 50G Ethernet specification uses two serdes lanes and an associated PCS/MAC layer to implement in silicon," Sankar said. "From a silicon design standpoint, both the switch and NIC have to handle PCS functions such as virtual lane alignment, auto-negotiation and forward error correction," he added.
