Video: Hyperscale Data Centers Drive Ethernet Innovation

Hyperscale data centers, such as those operated by Amazon and Google and Microsoft, are driving innovation in Ethernet, says Ahmet Houssein, Sr. VP and GM of QLogic's Ethernet Business Unit.  This short video highlights the need for 25G in these enormous, cloud facilities.

A new 2550100 Alliance has been formed by a group of server, storage, networking and software companies to focus on solutions based on new 25Gb, 50Gb and 100Gb Ethernet technology. http://www.2550100.com/

Ixia Offers 25 Gigabit Ethernet (GbE) Validation

Ixia is introducing a 25 Gigabit Ethernet (GbE) validation solution that builds on its native QSFP28 XcellonTM-Multis 100 GbE load modules to now provide 25GbE speed.

"25GbE is a good example of the networking industry responding to a growing need in an agile manner. With the unprecedented explosion of bandwidth requirements in the data center, new technologies like 25GbE must be deployed very quickly. Ixia is at the forefront of making this happen,” said Sunil Kalidindi, Vice President, Product Management of Ixia. “Ixia has developed the world’s first validation solutions for many Ethernet technologies, including 100GbE QSFP28, 400GbE, and now 25GbE. Ixia continues to be an industry leader in creating the solutions that help our customers develop and deploy Ethernet technologies, and successfully deliver application performance.”

Crehan: Multiple Technologies Drive Stronger Server Networking Upgrade Cycle

The availability of multiple new data-center Ethernet speeds will lead to a much stronger server networking upgrade cycle than seen over the past decade, according to a new Server-Class Adapter & LAN-on-Motherboard (LOM) Long-Range Forecast Report from Crehan Research.

The firm expects that the impending arrival of 25 gigabit Ethernet (GbE), 50GbE and 100GbE products, in combination with existing 10GbE and 40GbE products, will result in more than two-thirds of total networking ports migrating to high-speed Ethernet within three years (see accompanying figure).

“Over the past decade or so, the data center has seen many significant changes, and it is no longer a one-size-fits-all market,” said Seamus Crehan, president of Crehan Research. “Consequently, we are seeing solutions that are highly optimized for the needs of specific customer segments, whether it be a fully vertically integrated system for a converged enterprise network or a bare-bones disaggregated system for a massively scalable cloud service provider,” he said. “As a result, the market is currently looking for more targeted Ethernet networking solutions.”

The report predicts that the many various high-speed Ethernet options will coexist for some time, each benefitting from the demands of a specific market segment. For example:
  • 25GbE is expected to see a strong initial ramp from deployments by cloud titans such as Google and Microsoft, an area of the market where 10GbE server networking is currently prevalent. 
  • 10GbE should see its third, and biggest, adoption phase as the mainstream enterprise market upgrades its mostly 1GBASE-T server and server access infrastructure to 10GBASE-T.
  • 40GbE is starting to ramp significantly, benefitting from a current window of opportunity as the most attractively priced data center Ethernet speed from a bandwidth perspective. 

In both its 3Q14 Server-Class Adapter & LAN-on-Motherboard (LOM) Long-Range Forecast and its 3Q14 Data Center Switch reports, Crehan Research highlighted the dramatic uptake in 40GbE data center adoption, noting that networking bandwidth demands were so strong in some market verticals that these customers could not wait to evaluate impending 25GbE and 50GbE options.

Xilinx Announces 25G Ethernet IP for FPGAs

Xilinx announced low latency 25G Ethernet IP for FPGAs aimed at data center switching.

The low latency 25G Ethernet MAC and PCS LogiCORE IP solution supports the new 25G Ethernet Consortium specification and will be aligned with the industry's continuing advancements in next-generation processors, which are doubling their performance for tomorrow's data center servers.

Xilinx is demonstrating the 25G Ethernet MAC and PCS LogiCORE IP solution at this week's Supercomputing in New Orleans. The live demonstration utilizes two Virtex UltraScale VCU107 boards communicating over four channels of 25G Ethernet through 5 meters of direct attached copper cable and two QSFP+ modules.

IEEE Forms 25G Ethernet Study Group

A new IEEE 802.3 25 Gbps Ethernet Study Group has been formed to explore the market opportunities and needs for a single-lane 25 Gbps speed for server interconnects for Ethernet.

The reuse of serial lane 25 Gbps signaling technology, which was developed to support 100 Gbps Ethernet, enables cost optimized deployments in newly constructed data centers.

“The application of single-lane 25 Gbps signaling technologies provides Ethernet with a solution set that can be reused by those companies building the data centers of tomorrow. The new study group expects to lay the groundwork for a new Media Access Control (MAC) rate that will enable cost-optimized single-lane solutions that will increase network deployment efficiency,” said Mark Nowell, chair of the IEEE 802.3 25 Gbps Ethernet Study Group and senior director, Cisco Systems. “The heavy lifting in developing and standardizing 25 Gb/s signaling technologies has been done as part of the development of 100 Gbps Ethernet. These technologies can be reused to enable a single-lane 25 Gbps Ethernet solution set for server interconnects for these future data centers.”

Coming Soon -- 25 and 50 Gigabit Ethernet

A new industry consortium, including Arista Networks, Broadcom, Google, Mellanox Technologies, and Microsoft, announced the availability of a specification optimized to allow data center networks to run over a 25 or 50 Gigabit per second (Gbps) Ethernet link protocol. The specification prescribes a single-lane 25 Gbps Ethernet and dual-lane 50 Gbps Ethernet link protocol, enabling up to 2.5X higher performance per physical lane or twinax copper wire between the rack endpoint and switch compared to current 10 Gbps and 40 Gbps Ethernet links. The new specification is being made available royalty-free by the Consortium members to any data center ecosystem vendor or consumer who joins the Consortium.

The 25 Gigabit Ethernet Consortium said its mission is to support an industry-standard, interoperable Ethernet specification that boosts the performance and slashes the interconnect cost per Gbps between the server Network Interface Controller (NIC) and Top-of-Rack (ToR) switch. The new specification covers 25 Gbps and 50 Gbps Ethernet physical layer (PHY) and media access control layer (MAC) behavior, including virtual lane alignment, autonegotiation, and forward error correction characteristics.

“We believe that 25 and 50 Gigabit Ethernet (GbE) serves a focused market requirement for next-generation, performance and cost optimized server- and storage-to-switch interconnects and are proud to be a key contributor to the Consortium’s 25 and 50 GbE specification," stated Rochan Sankar, Product Marketing Director, Infrastructure and Networking Group, Broadcom.

“The companies joining the 25 Gigabit Ethernet Consortium are taking a major step forward in increasing the performance of data center networks,” said Anshul Sadana, Senior Vice President, Customer Engineering, Arista Networks. “With ever-increasing server performance and with the uplinks from the leaf to the spine layer migrating to 100 Gbps in the near future, it makes sense to increase the access speed from 10 Gbps to 25 and 50 Gbps.”
