The fourth-generation (T4)
technology from Chelsio pro-
vides the highest 10GbE perfor-
mance available and dramatical-
ly lowers host-system CPU com-
munications overhead with on-
board hardware that off-loads
TCP/IP, iSCSI, FCoE and iWARP
RDMA processing from its host
system. T420-CR frees up host
CPU cycles for useful applica-
tions. The system achieves in-
creased bandwidth, lower laten-
cy, and lower power.

The Unified Wire Solution
With the T420-CR, 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.

The adapter’s two ports and IEEE 802.3ad link aggregation/failov er fea-
tures are ideal for critical network applications that require redundancy
and high-availability capabilities.
