Overview
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 hostsystem CPU communications overhead with onboard 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 filebased 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.

T4 - Fourth-Generation Protocol Offload Engine
The T4 is Chelsio’s fourth‐generation TCP offload (TOE) design, third‐
generation iSCSI design, and second‐generation iWARP (RDMA) implementation. For the server connection, the T4 chip includes a PCI
Express v2.0 ×8 host interface. With support for the 5Gbps Gen2 data
rate, the PCIe interface provides up to 32Gbps of bandwidth to the
server. T4 also adds support for PCIe I/O virtualization. Most of T4
features are enhanced versions of those found in T3. Features that
carry over from T3 include stateless offloads, packet filtering (fir ewall offload), and traffic shaping (media streaming).
Complete and Flexible TCP Offload
The T4 has hundreds of programmable registers for protocol configuration, RFCs, and offload control. The T440-LP-CR can offload
TCP processing per connection, per-server, per-interface, and globally and simultaneously tunnel traffic from non-offloaded connections to the host processor for the native TCP/IP stack to process.
The T440-LP-CR provides a flexible zero copy capability for regular
TCP connections, requiring no changes to the sender, to deliver line
rate performance at minimal CPU utilization.
