Chelsio’s S302E-C multi-port 1GbE adapters offer best-of-class performance
and features, including IP/UDP/TCP checksum and large send offload, rate
control and QoS, virtualization, and rule-based traffic steering and filtering.
and features, including IP/UDP/TCP checksum and large send offload, rate
control and QoS, virtualization, and rule-based traffic steering and filtering.
These adapters employ Chelsio’s unique third-generation Terminator 3 ASIC,
a high-performance, programmable protocol processor. Terminator 3 pro-
cesses all connections in a single datapath to deliver line-rate 1Gbps or
10Gbps performance with one connection, up to thousands of connections.
In contrast, competitive multi-RISC offload engines, which rely on having
enough connections to distribute their processing among parallel processors
to achieve full performance, are ultimately limited by the performance of each
processor.

In contrast, competitive multi-RISC offload engines, which rely on having

The Terminator 3 ASIC has hundreds of programmable registers for protocol
configuration, RFCs, and offload control. Chelsio’s multi-port 1GbE adapters
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. These adapters pro-
vide a flexible zero copy capability for regular TCP connections, requiring no
changes to the sender, to deliver line rate performance at minimal CPU utili-
zation.

Chelsio’s multi-port adapters offload the expensive byte touching iSCSI oper-
ations and payload placement to greatly accelerate iSCSI performance for IP
SAN applications while maintaining flexibility. The iSCSI protocol itself can be
implemented by vendors to provide product differentiation. These adapters
also implement a high-capacity, low-latency, high-bandwidth iWARP
RDMA/RDDP, which adheres to the IETF standards.

Subjected to thousands of hours of compatibility testing, over three years of
stress testing by several OEM test suites and production deployments in serv-
ers, storage systems and cluster computing, Chelsio’s robust, stable protocol
offload technology delivers proven performance in a wide range of environ-
ments. Chelsio’s adapters are generations ahead of competing products.

The S302E-C is available with a full suite of protocol software and drivers for
Windows (Chimney). The software supports both protocol-offload and non-
offload modes.
