Arastra Extends 10 Gigabit Datacenter Ethernet Switch Family

Las Vegas, NV, April 29, 2008 - Arastra today announced the Arastra 7148S, a new addition to the Arastra 7100 Series of 10G Datacenter Ethernet switches optimized for rack-top server aggregation.

"The Arastra 7148S establishes a new class of price-performance that makes 10 Gigabit Ethernet an even more compelling solution for wide-scale data center deployments", said Mansour Karam, Director of Marketing and Business Development at Arastra.

The Arastra 7148S, a 1-rack-unit L2/L3/L4 48-port 10GbE SFP switch with 800 Gbps of bandwidth, complements the previously-announced Arastra 7124S 24-port 10GbE switch with 480 Gbps of bandwidth, and the Arastra 7148SX 48-port 10GbE switch with 960Gbps of bandwidth. All Arastra 7100 Series switches share the same 1-rack-unit enterprise chassis with front to back cooling and run Arastra's extensible operating system EOS.

"After using 1 Gigabit Ethernet for almost a decade, the time is right to investigate server solutions utilizing 10 Gigabit network servers," explained Helmut Tschemernjak, CEO of German based HELIOS Software GmbH, a leading provider of high performance networking and client/server software products. "The Arastra 7100 switch demonstrated record performance from a server running HELIOS UB+," according to Tschemernjak, "which is good news for our demanding enterprise server and prepress customers."

Industry innovations of the Arastra 7100 Series include:

• Arastra EOS, a modular operating system based on a unique multi-process state-sharing architecture that separates networking state from the processing itself. This enables fault recovery and incremental in-service software updates (ISSU) on a per-process basis without affecting the state of the system. In addition, EOS enables integration with customer infrastructure and virtualized environments via open management and control APIs.
• Highest 10 GbE port density with 48 10 GbE ports in a 1-RU chassis, supporting a rack level density of 2016 10 GbE ports per 42-RU rack
• Front-to-rear airflow in both forward- and reverse-mounting configurations, hot-swappable redundant power supplies, hot-swappable redundant cooling, and dual redundant management ports
• Support for a full range of 10 Gigabit SFP+ and Gigabit SFP interface options, including 10GBASE-SR, 10GBASE-SRL, 10GBASE-LR, 10GBASE-LRM, and 10GBASE-CR, which allows cost-effective connectivity within the rack using passive copper cables.

"We have been using the Arastra 7100 switches in our environment for some time now," said Kim Cupps, High Performance Systems Division Leader in Computation at Lawrence Livermore National Laboratory (LLNL) in California. "To deploy our next generation petascale simulation environment, LLNL will need the cost/performance value, density, and scalability provided by this new datacenter platform." Cupps added, "To meet the HPC demands of our research programs, we require a versatile network operating system with the ability to do in-service software upgrades (ISSU) and the ability to customize the switch to specific environments, both of which are provided by Arastra EOS."

The Arastra 7124S and 7148SX are available today. The Arastra 7148S will be available in Q3'08.
