FOR IMMEDIATE RELEASE

DNUK SELECTS CHELSIO’S T210-CX iSCSI TARGET SOLUTION

SUNNYVALE, CA, FEBRUARY 23, 2006 – Chelsio Communications Inc., the leading provider of iSCSI acceleration adapter and ASIC solutions, and DNUK, one of the UK’s leading suppliers of Linux workstations, server and storage systems, today announced that DNUK is offering Chelsio’s T210-CX4 10GbE TOE/iSCSI acceleration adapters as a component of its line of next-generation storage systems targeting Linux enterprise environments.

Chelsio’s T210-CX4 TOE/iSCSI adapter and iSCSI Target software v1.0 is a proven turnkey solution set that offers significant cost savings for storage target systems by leveraging the volume, scalability, and simplicity of off-the-shelf server platforms, standard Ethernet connectivity, and copper CX-4 cabling. T210-CX has been measured to deliver more than 600K IOPS and 7.9G (limited by PCI-X 1.0 bandwidth) throughput when used with the Chelsio iSCSI Target stack running in RAMdisk mode and Microsoft initiators.

Using Chelsio T210-CX and iSCSI Target v1.0, DNUK has created a complete line of iSCSI and direct attached storage (DAS) systems. The products can easily scale to meet the resiliency, storage performance and capacity requirements of Linux enterprise and data center applications, ranging from e-commerce to scientific applications. The DNUK systems will be available in March.

Chelsio is happy to have DNUK as an innovative OEM offering storage solutions based on our T210-CX line of products,” said Kianoosh Naghshineh, president and CEO of Chelsio. DNUK’s use of our T210-CX4 and commercial grade iSCSI target stack for its novel DAS and SAN connectivity offering is additional validation of the storage value proposition of 10 Gigabit Ethernet.

We view the T210-CX as a critical enabler for our IP SAN and DAS storage solutions to shatter performance limitations of existing approaches, said Lee Chisnall, director of DNUK. “We’re excited about the opportunity to bring high value 10GbE-based storage solutions to enterprise Linux users. Our Teravault storage systems combined with industry-leading RAID and Chelsio 10GbE offer an unbeatable price/performance solution.

The Chelsio T204 and T210 in combination with the Chelsio iSCSI Target software are complete, turnkey iSCSI target solutions that enable OEMs to deliver high-performance iSCSI target appliances. Modular and scalable, the T204 and T210 are the most advanced iSCSI acceleration solutions available today for creating iSCSI-enabled network storage devices. The T204 and T210 are compatible with all IETF compliant initiators and have been thoroughly validated with initiators available with Microsoft Windows and various Linux distributions.
