IBM Power Systems selects Chelsio Unified Wire as 10G Ethernet Interconnect


Concurrent iSCSI, iWARP, NIC Operation Enables Fabric Convergence

SUNNYVALE, CA – Oct. 5, 2009 - Chelsio Communications, Inc., the leading provider of 10-Gigabit Ethernet (10GbE) adapters and ASIC solutions, today announced its high performance Unified Wire 10GbE adapter cards will serve as the PCI-Express 10GbE interconnect for the IBM Power System server platforms.

Chelsio’s solution is uniquely capable of concurrently addressing high performance Ethernet iWARP, RDMA clustering and iSCSI solutions, said Karl Duvalsaint, director of Integrated Systems Development for IBM Systems & Technology Group. The flexibility of the Unified Wire technology fits well with the demanding and feature rich installations served by IBM Power servers.

Chelsio Unified Wire adapters are the highest performance 10GbE adapters for storage, server and cluster networking.  The adapters for use with the IBM Power Systems include the low profile S310e-SR+ optical and S310e-CXA CX4 copper adapters.  The adapters operate as a 10GbE NIC for Linux and AIX platforms, and concurrently as iSCSI and iWARP adapters as well on Linux platforms.  All the products are generally available from IBM on all POWER6 platforms.

IBM Power Systems support the AIX and Linux operating environments and span all IBM systems based on industry-leading Power Architecture, including the POWER6 microprocessor.  They deliver a robust combination of performance and manageability for a server platform, ideal for virtualized environments.  IBM Power Systems provide a flexible, cost-efficient, resilient, secure, and scalable solution for AIX and Linux environments with outstanding performance.

The qualification process for the IBM Power Systems was truly demanding, so our robust Unified Wire adapters and processes were further hardened as a result to enable high performance, feature-rich, and scalable solutions required by IBM Power, said Kianoosh Naghshineh, president and CEO of Chelsio.  We are very pleased to deliver the 10GbE Unified Wire interconnect for the IBM Power Systems customers.
