Arastra Extends 10 Gigabit Datacenter Ethernet Switch Family

LAS VEGAS--(Business Wire)--
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.
