Chelsio has also introduced the T420-BT, a dual-port 10GBase-T Ethernet adapter.
 
Both new adapters are based on the fourth generation T4 technology, and enable a Unified Wire for LAN, SAN and cluster traffic, providing offload of TCP, UDP, iSCSI, FCoE and iWARP traffic simultaneously with support for major virtualization technology in the market.

The cards are optimized for cloud computing, HPC, storage and other data center applications. Benchmark testing of the T440 showed saturated throughput for the PCI Express 2.0 interface and latencies of sub 3.0 microsecond for WD-UDP and 5.0 microsecond for TCP traffic.
 
"There is growing demand for 10GbE in datacenter server and storage networking, with port shipments in this segment almost doubling year-over-year," said Seamus Crehan, president of Crehan Research. "Furthermore, an ever-increasing number of customers are looking for high performance, flexible solutions that can converge multiple protocols and lower TCO."
 
The T440-LP-CR is a 4x10Gb Ethernet, low profile, PCI 2.0 Express bus interface, with 32,000 offloaded connections and one QSFP+ port that uses standard cables or a single octopus cable that has a QSFP+ transceiver on one end and four SFP+ transceivers on the other end. This enables the Unified Wire adapter to deliver 40Gb bandwidth without the need for a premium 40Gb Ethernet switch port, allowing low cost per gigabit link.
 
The T440-LP-CR is well-suited to deliver storage applications via the high throughput and the ability to run NFS, Lustre and other file systems over RDMA. In small storage clusters the T440-LP-CR aggregates four servers into a storage target and removes the need for additional equipment altogether, resulting in lower IT costs.
 
The T420-BT is a dual port 10GBase-T Unified Wire adapter with PCI Express 2.0 host bus interface. It is capable of providing two 1/10GbE ports by using standard RJ-45 connectors with twisted pair Cat-6a cables.
 
US List pricing for the T440-LP-CR is $899 and the T420-BT is $999. Both cards are available from Chelsio and its distributors.
