CHELSIO DELIVERS WORLD RECORD ETHERNET PERFORMANCE.

Chelsio Communications, Inc., Sunnyvale, Calif., has again set a new world record for Internet data transfer using its unique 10 gigabits-per-second TCP/IP offload technology together with AMD Opteron(TM) processor-based systems. Chelsio is joining AMD (NYSE:AMD) in celebration of the 2nd anniversary of the AMD Opteron processor and the growing AMD64 ecosystem by announcing this new world record using both companies' industry-leading products and technologies.

"The combination of high-performance AMD Opteron processors and Chelsio's unique 10 gigabits-per-second protocol offload technology allows for much greater application CPU cycles per dollar," said Kianoosh Naghshineh, president and CEO of Chelsio Communications. "By coordinating routine network processing tasks between the CPU and Chelsio's protocol engine, AMD Opteron processors are dedicated to running the application programs, thereby resulting in a very high performing and extremely efficient server solution."

The University of Tokyo, Chelsio Communications and an international team of engineers established the world's longest 10 Gigabit per second link ever recorded for the transmission of internet data by connecting two AMD Opteron processor-based servers over three continents, spanning 17 time zones and reaching more than half way around the world. Each server was equipped with a Chelsio 10 Gigabit Ethernet Protocol Engine with TCP/IP offload technology. A transfer rate of 7.21 Gigabits per second was sustained using a single TCP stream and standard 1500-byte Ethernet frames over trans-continental link, breaking the world record. At this transfer rate and distance, a full-length DVD can theoretically be transferred anywhere on the earth in under 5 seconds.

"Chelsio's 10 Gigabit Ethernet adapter with TCP/IP offload technology is an excellent complement to the AMD Opteron(TM) processor with Direct Connect Architecture, which was designed to offer balanced I/O bandwidth and deliver the greatest value to enterprise customers," said Pat Patla, director, server/workstation, Microprocessor Solutions Sector, AMD. "The incredible performance of AMD Opteron processors and Chelsio's 10G TOE adapters are enabling record-breaking network speeds."

At 10 gigabits-per-second rates, it's widely accepted that CPU throughput limits performance. Chelsio's TCP/IP offload engine (TOE) technology enables higher CPU throughput, extending the application performance of servers and resulting in lower total cost of ownership for data centers. Similarly, AMD's revolutionary Direct Connect Architecture continues to be the best approach of directly connecting CPU, memory, and I/O resources to improve the overall system performance and efficiency. Working closely with partners such as Chelsio Communications, AMD has raised the standards for high-performance computing.
