Introduction
Chelsio single-port and dual-port adapters for IBM System Cluster 1350 and IBM iDataPlex are 10 Gigabit Ethernet adapters with PCI Express host bus interface optimized for virtualization, high performance computing, and storage applications. The third generation technology from Chelsio provides the highest 10GbE performance that is available and dramatically lowers host system CPU communications overhead.
With on-board hardware that off-loads TCP/IP, iSCSI, and iWARP RDMA processing from its host system, these adapters free up host CPU cycles for business applications and result in increased bandwidth, lower latency, and lower power. This combination makes it practical to converge other networks that traditionally used niche technologies onto 10GbE. High bandwidth and extremely low latency make 10GbE with protocol offload the best technology for high-performance cluster computing (HPCC) fabrics.
