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.
The Unified Wire Solution
With the T420-BT, Chelsio is enabling a unified wire for LAN, SAN and cluster traffic. This unified wire was made possible by the high band-width and low latency of 10GbE combined with storage and cluster pro-tocols operating over TCP/IP (iSCSI, FCoE and iWARP respectively).
In parallel, operating systems and hypervisors have incorporated native support for iSCSI and database applications are now supporting file- based storage protocols such as NFS as an alternative to SANs.
T420-BT includes a full-fledged integrated Traffic Manager for robust flow control, traffic management and QoS.
Fibre Channel over Ethernet (FCoE) provides a transition path from lega-cy SANs to converged networks. Expanding its unified wire approach, Chelsio has added FCoE hardware support to the new T420-BT adapter.
The adapter’s quad ports and IEEE 802.3ad link aggregation/failover fea-tures are ideal for critical network applications that require redundancy and high-availability capabilities.
T420-BT Ethernet-only networking reduces the data center’s cost in net-work adapters, cables, switches, rack space, power, equipment spares, management tools, planning, networking skills, and installation.
