Arista Networks, Broadcom, Google, Mellanox and Microsoft Collaborate on New
Ethernet Specification to Drive Greater Performance and Cost Efficiency for
Next Generation Data Centers

SANTA CLARA, Calif., July 1, 2014

SANTA CLARA, Calif., July 1, 2014 /PRNewswire/ --A consortium of companies
including Arista Networks (NYSE: ANET), Broadcom Corporation (NASDAQ: BRCM),
Google Inc. (NASDAQ: GOOG, GOOGL), Mellanox Technologies, Ltd. (NASDAQ: MLNX),
and Microsoft Corp. (NASDAQ: MSFT) today 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. This new specification will
enable the cost-efficient scaling of network bandwidth delivered to server and
storage endpoints in next-generation cloud infrastructure, where workloads are
expected to surpass the capacity of 10 or 40 Gbps Ethernet links deployed
today.

The 25 Gigabit Ethernet Consortium was formed by the above leading cloud
networking technology providers for the purpose of supporting 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
specification adopted by the Consortium 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 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."

By deploying 25 and 50 Gbps Ethernet in their networks, builders of mega-scale
data centers such as Microsoft expect to achieve operational advantages,
including reduced CapEx and OpEx. "The new Ethernet speeds proposed by the
Consortium give superior flexibility in matching future workloads with network
equipment and cabling, with the option to 'scale-as-you-go,'" said Yousef
Khalidi, Distinguished Engineer, Microsoft. "In essence, the specification
published by the 25 Gigabit Ethernet Consortium maximizes the radix and
bandwidth flexibility of the data center network while leveraging many of the
same fundamental technologies and behaviors already defined by the IEEE 802.3
standard."

The companies' motivation for founding the Consortium is to immediately set an
industry standard definition of the 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,
to enable the swift rollout of 25 Gbps and 50 Gbps Ethernet compliant
implementations over the next 12 to 18 months through the participation of
multiple semiconductor, networking equipment and interconnect vendors in the
Consortium.

"Broadcom has long been a strong proponent and contributor of new Ethernet
standards that have served the advancement of data center and cloud-scale
networks," said Rochan Sankar, Product Marketing Director, Infrastructure and
Networking Group, Broadcom. "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."

"The growth in data creation and usage mandates faster and more efficient
interconnect technologies," said Michael Kagan, Chief Technology Officer,
Mellanox Technologies. "Mellanox provides a wide variety of interconnect
solutions ranging from 10 to 100 Gbps, and endorses open industry
collaboration to enable further interconnect flexibility and speeds."
