![](/p.gif) | Chelsio’s T580-CR is a dual port 40 Gigabit Ethernet Unified Wire adapter with PCI Express 3 host bus interface, optimized for cloud computing, HPC, virtualization, storage, and other data center applications.
The fifth-generation (T5) technology from Chelsio provides the highest 40GbE performance available and dramatically lowers host-system CPU communications overhead with on-board hardware that off-loads TCP/IP, iSCSI, FCoE and iWARP RDMA processing from its host system. T580-CR frees up host CPU cycles for useful applications. The system achieves increased bandwidth, lower latency, and uses less power.
The T580-CR sets itself apart from other other 40Gb offerings from Chelsio in that it provides dual-paths to the external memory on the adapter thereby allowing offloaded connections, such as TOE and iSCSI, to achieve the maximum bandwidth provided by the card.
