Chelsio Delivers TOE Supporting Microsoft TCP Chimney

By licensing Alacritech's patents

Chelsio Communications Inc. announced
availability of its TCP/IP offload engine (TOE) technology fully
supporting the Microsoft TCP Chimney architecture. 

Microsoft TCP
Chimney allows Windows operating systems to offload network TCP
processing from the CPU to the network controller. Chelsio is
licensing Alacritech Inc. patents to enable Chimney driver support.

TCP/IP
processing consumes a high amount of server CPU cycles and at 10Gbps
rates, it places a tremendous load on the memory subsystem and the need
to offload this burden from the server becomes critical. TCP
Chimney-enabled Chelsio adapters not only free the host CPU from
network processing, but also, by eliminating data copy, free up memory
bandwidth for processing of applications, thus improving overall
application performance and server efficiency.

Performance
testing results show that Chelsio’s 10GbE TOE, running with Microsoft’s
TCP Chimney stack, doubles network throughput and improves CPU
utilization by up to eight times as compared to the same server running
without a TOE.  In fact, the utility cost savings enabled by TCP
Chimney over the data center server refresh cycle are easily a multiple
of the cost of the server itself: TCP Chimney allows more compute
power for the investment for the data center managers. Further,
Chelsio’s hardware offload engine also accelerates TCP/IP processing
times, yielding better response times and no latency variations for
networked applications – critical to the performance of interactive
applications.

This major milestone
is the result of our long-term collaboration with Microsoft and
supports our overall vision for a unified data center fabric
,” said
Kianoosh Naghshineh, president and CEO of Chelsio Communications.
Available today, our 10GbE Chimney protocol offload engine opens the
way for broad adoption throughout the network, and has set a new
standard for TCP/IP offload engine technology. Our T3 10GbE solution
addresses the performance acceleration requirements of CIFS, iSCSI and
general networking applications. The results are clear: using Chimney
results in higher bandwidth, lower CPU utilizations, lower server power
consumption, and lower latencies
.”

“The
outstanding performance, robustness, and scalability of the TCP Chimney
architecture are major successes for Microsoft.  We are very pleased to
see the availability of the Chimney-compliant 10 Gigabit Ethernet
solution from Chelsio
,” said Mike Schutz, director of product
management for Windows Server at Microsoft. “Microsoft is pleased to
be working with partners like Chelsio to enable broad-based deployment
of 10GbE TCP Chimney offload within Windows data centers
.”

Chelsio Chimney TOE adapters are shipping today.  Pricing is $1795 for the S310e-SR-C and $895 for the S302e-C adapter.
