Chelsio Communications has expanded its 10GigE portfolio with the introduction of 10Gb Ethernet adapter cards based on the new 10GBASE-T (IEEE 802.3an) standard interface for 10Gb transmission over Category 6 or Category 7 copper cabling.
Chelsio is announcing two new 10Gb Ethernet cards, the S310e-BT storage adapter and the N310e-BT server adapter. Both cards offer a single dual-speed auto-negotiating 1GbE/10GbE port, and support the PCI-Express host bus interface. The dual speed feature allows an immediate upgrade of server interconnects to 10G, while preserving the interoperability with existing 1G switches.
The S310e-BT is powered by Chelsio’s Terminator 3 (T3) ASIC and Teranetics’ TeraPHY TN1010 transceiver. The T3 fully offloads TCP/IP, iSCSI and iWARP RDMA processing from the host system. Protocol offload reduces CPU utilization by up to 90%, and decreases system power consumption, while increasing network bandwidth, and lowering communication latency. With these benefits, it becomes possible to converge applications that traditionally used niche technologies onto 10Gb Ethernet.
The N310e-BT is a stateless offload server adapter, delivering the highest throughput for 10Gb Ethernet server applications. With the N310 series, enterprises can cost effectively connect servers and storage systems directly to the 10GbE backbone switching infrastructure now using RJ-45 connectors, in addition to the previously available fiber and CX-4 copper.
