Chelsio’s T420-BT is a dual port 10GBase-T 10 Gigabit Ethernet Unified Wire adapter with PCI Express 2.0 host bus interface. It is capable of providing two 10GbE ports by using standard RJ-45 connectors with Twisted Pair Cat-6a cables. T420-BT is optimized for cloud computing, HPC, virtualization, storage, and other data center applications. The fourth-generation (T4) technology from Chelsio provides the highest 10GbE performance 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.
