Overview
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.
The Unified Wire Solution
With the T420-LL-CR, Chelsio is enabling a unified wire for LAN, NAS, 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.
T420-LL-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 T420-LL-CR adapter.
The adapter’s two ports and IEEE 802.3ad link aggregation/failover features are ideal for critical network applications that require redundancy and high-availability capabilities.
T420-LL-CR Ethernet-only networking reduces the data center’s cost in network adapters, cables, switches, rack space, power, equipment.
