Chelsio T580-CR Network Card Dual-Port QSFP+ 40 Gbit T580-CR

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 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.
