Chelsio T520-SO-CR Dual-Port 10 Gigabit Ethernet Adapter SFP+

Chelsio T520-SO-CR: Call for price

     Chelsio’s T520-SO-CR is a memory free dual-port 10 Gigabit Ethernet adapter with a PCI Express 3.0 host bus interface, optimized for cloud computing, virtualization, storage, and other data center applications. This adapter, based on the fifth-generation (T5) technology from Chelsio provides the highest 10GbE performance available and dramatically lowers host-system CPU communications overhead with on-board hardware that off-loads TCP/IP processing from its host system. T520-SO-CR frees up host CPU cycles for useful applications. The system achieves increased bandwidth, lower latency, and uses less power. T520-SO-CR integrates a high performance packet switch, which allows switching traffic from any of the input ports to any of the output ports (wire-to-wire) and from any of the output ports to any of the input ports (host-to-host).
