Chelsio Delivers 40Gb Ethernet Adapter; Sets New Performance Bar For High Speed Ethernet

Jun 11, 2013, 14:10 ET from Chelsio Communications, Inc.

SUNNYVALE, Calif., June 11, 2013 /PRNewswire/ -- Chelsio Communications, a leading provider of 10Gb Ethernet Unified Wire Adapters and ASICs, today announced the availability of the first set of 40Gb Ethernet network adapters based on the fifth generation of its hyper-virtualized unified wire Terminator ASIC architecture.  The T5 powered adapters are the industry's highest performance Ethernet interfaces, delivering wire speed bandwidth, ultra low latency and high message processing capacity. With a comprehensive suite of offloaded storage, compute and networking protocols – including RDMA, TCP/IP, UDP/IP, iSCSI and FCoE with T10-DIX – T5 enables network convergence and provides unprecedented performance in virtualized environments, while dramatically increasing host system efficiency and lowering communications overhead. 


"Adapters that can deliver a rich feature-set in conjunction with high performance from 10Gb to 40Gb should see success in the market," said Seamus Crehan, president of Crehan Research.  "The converged nature of the features on the T5 adapters should enable their use in a variety of verticals and consolidate applications on a single interface."

The new T5 based cards are high performance drop-in replacements for any FibreChannel or InfiniBand adapter in BSD, Linux and Windows environments:

  • T520-LL-CR:  a dual-port, ultra low latency 10 Gigabit Ethernet Unified Wire adapter with a PCI Express 3.0 host bus interface, optimized for financial and HPC applications, with over 6M messages/sec capacity and near zero jitter. It is also a Best in Class 10 GbE interconnect solution for cloud computing, virtualization, storage, and other data center applications.  The T520-LL-CR provides 1.5usec end-to-end latency to user-space TCP, UDP and RDMA applications, and is capable of 2x10G full duplex line rate forwarding performance with 64B packets in RFC 2544 testing.
  • T580-LP-CR:  a dual-port 40 Gigabit Ethernet Unified Wire adapter with PCI Express 3.0 host bus interface, optimized for cloud computing, HPC, virtualization, storage, and other data center applications. The T580-LP-CR provides ultra low latency and line rate 40Gbps full duplex performance for iSCSI, FCoE, TCP/IP, UDP/IP and RDMA users, and is the only adapter capable of 40Gb line rate operation at 8KB I/O with Windows 2012 SMB-Direct.

Both adapters have true dual-channel active-active operation capability with failover support between ports and between adapters, qualifying them for deployment in enterprise critical applications.

"Besides offering uncompromising performance and a rich feature set, T5 adapters are supported by the most comprehensive suite of software of any solution in the industry," said Kianoosh Naghshineh, CEO of Chelsio.  "This will truly enable the OEMs to standardize on a single vendor for all networking applications, thereby reducing qualification and inventory carrying costs."

A natural evolution of the scalable T4 architecture, T5 leverages all the software developed for T4, and in turn, T5 software is compatible with T6, allowing all investments to be future proofed for 100Gbps applications.

Chelsio is demonstrating the T5 adapters and their performance at the International Super Computing Conference in Leipzig, Germany on June 17-20.

Availability and Pricing
The T5 adapters are available now from Chelsio's distributors with standard lead times.  T520-LL-CR is street priced at $975.  T580-LP-CR is street priced at $945.  T5 layer 2 and low latency middleware software is available for download at no additional licensing fees. Offload software is currently available in beta, at no additional licensing fees.
