Chelsio''s T540-CR is a quad port 10 Gigabit Ethernet Unified Wire adapter with a PCI Express 3.0 host bus interface, optimized for cloud computing, HPC virtualization, storage, and other data center applications. Since the Host Bus Interface is PCI Express 3.0, this card can support all 4 10G ports running at line-rate. The fifth-generation (T5) technology from Chelsio provides the highest 10GbE performance in the industry and dramatically lowers host-system CPU communications overhead with on-board hardware that offloads TCP/IP, iSCSI, FCoE and iWARP RDMA processing from the host system and frees up host CPU cycles for other applications. As a result, the system benefits from higher bandwidth, lower latency, and reduced power consumption.
