Chelsio 10 GbE adapters for IBM Power Systems are high performance, 10 Gb Ethernet adapters with PCI Express host bus interfaces optimized for virtualization, high performance computing, and storage applications. The third generation technology from Chelsio used in these adapters provides the highest 10 GbE performance available and dramatically lowers the host system's CPU communications' impact.

Chelsio 10 GbE adapters for IBM Power Systems are high performance, 10 Gb Ethernet adapters with PCI Express host bus interfaces optimized for virtualization, high performance computing, and storage applications. The third generation technology from Chelsio used in these adapters provides the highest 10 GbE performance available and dramatically lowers host system's CPU communications' impact.

With on-board hardware that off-loads TCP/IP, iSCSI, and iWARP RDMA processing from its host system, single port adapters frees up host CPU cycles for useful applications, which results in increased bandwidth and lower latency. This combination makes it practical to converge other networks that traditionally used niche technologies onto 10 GbE Ethernet adapters. High band-width and extremely low latency make 10 GbE Ethernet adapters with protocol offload the best technology for high-performance cluster computing (HPCC) fabrics.
