Chelsio Delivers 10GbE Unified Wire Fully Integrated With Citrix XenServer 4.1

'In-Box' Drivers Enable Industry's Highest I/O Performance For Leading Server
Virtualization Platform

SUNNYVALE, Calif., April 28 /PRNewswire/ -- Chelsio Communications, Inc.,
the leading provider of 10-Gigabit Ethernet (10GbE) adapters and ASIC
solutions, today announced new software drivers that are fully integrated
within the newly released XenServer 4.1 from Citrix Systems Inc.
(Nasdaq: CTXS). The 'in-box' drivers provide seamless deployment of Chelsio
10GbE Unified Wire adapters with Citrix XenServer 4.1, enabling the industry's
best I/O performance for single or multiple Windows and Linux virtual machines
(VM) while delivering on the promise of the unified wire.
The Chelsio adapters are based on Chelsio's 3rd generation T3 ASIC, which
delivers the highest bandwidth and lowest latency in the industry. The
drivers for XenServer 4.1 have gone through a rigorous qualification process
by both Citrix and Chelsio for the Citrix release of XenServer 4.1, which
insures seamless installation. Chelsio is an official Citrix Ready partner.
"Chelsio's integrated 10GbE drivers for XenServer 4.1 are very easy to
use, and can substantially boost the network performance of virtualized
environments," said Jason Timmins, technical director at InterLinx, Ltd,
a UK-based internet service provider. "We can now run even more network-
intensive workloads on each virtual machine without sacrificing application
performance."
Citrix XenServer 4.1 permits enhanced scalability, faster performance, and
the ability to conduct virtual infrastructure platform upgrades and automated
patching with zero downtime. The 4.1 release also includes many other new
capabilities, including support for 10Gb/s networking, bonding, and 64-bit
enterprise Linux guests. As part of the qualification process, Chelsio is
included in the Citrix hardware compatibility list.
"Chelsio's 10GbE drivers for XenServer 4.1 deliver line-rate performance,
which greatly boosts the value of XenServer 4.1 for the range of high-
throughput applications," said Matt Fairbanks, vice president of product
marketing for XenServer at Citrix. "Our customers can now run their most
network-intensive workloads on their virtual servers and achieve the best
overall performance in the industry."
"Virtualization support is a key attribute of our T3 unified wire
technology, and we are pleased to be the only vendor in the industry that has
delivered full 10G line-rate I/O performance for virtualized server
environments using a single VM," said Kianoosh Naghshineh, president and CEO
of Chelsio. "Citrix's customers enjoy the cost benefits and richness of
XenServer 4.1 virtualization while maintaining the performance and cost
advantages of Chelsio's unified wire solutions."
The adapters for Citrix XenServer 4.1 are available today from Chelsio and
its distribution partners. Chelsio will be demonstrating its virtualization
solutions, including iSCSI and TOE capabilities for XenServer, at Interop Las
Vegas '08, April 29-May 1, at Mandalay Bay Hotel in Las Vegas.
