Chelsio 4-Port 10 Gigabit Ethernet Low Profile QSPF+ Unified Wire Adapter

Chelsio’s T440-LP-CR is a single QSFP+ port 10 Gigabit Ethernet Unified Wire adapter with PCI Express 2.0 host bus interface. It is capable of providing four 10GbE ports by using a special octopus cable that has a QSFP transceiver on one end and four SFP+ transceivers on the other end.

T440-LP-CR 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 T440-LP-CR, Chelsio is enabling a unified wire for LAN, SAN and cluster traffic. This unified wire was made possible by the high bandwidth and low latency of 10GbE combined with storage and cluster protocols 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.

T440-LP-CR 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 legacy SANs to converged networks. Expanding its unified wire approach, Chelsio has added FCoE hardware support to the new T440-LP-CR adapter.

The adapter’s quad ports and IEEE 802.3ad link aggregation/failover features are ideal for critical network applications that require redundancy and high-availability capabilities. T440-LP-CR Ethernet-only networking reduces the data center’s cost in network adapters, cables, switches, rack space, power, equipment spares, management tools, planning, networking skills, and installation.
