Chelsio's T420-LL-CR is a dual port, low latency 10 Gigabit Ethernet Unified Wire adapter with PCI Express 2.0 host bus interface, optimized for financial and HPC applications. It is also a best in class 10GbE interconnect solution for cloud computing, virtualization, storage, and other data center applications.

The fourth-generation (T4) 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, iSCSI, FCoE and iWARP RDMA processing from its host system. T420-LL-CR frees up host CPU cycles for useful applications. The system achieves increased bandwidth, lower latency, and lower power.
