The S310E offers 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.
checksum and large send offload, rate control and QoS, virtualization, and rule-
based traffic steering and filtering.
The S310E employs Chelsio’s unique third-generation Terminator 3 ASIC, a high-
performance, programmable protocol processor. Terminator 3 processes all con-
nections in a single datapath to deliver line-rate 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 pro-
cessing among parallel processors to achieve full performance, are ultimately lim-
ited by the performance of each processor.

offload engines, which rely on having enough connections to distribute their pro-
cessing among parallel processors to achieve full performance, are ultimately lim-
ited by the performance of each processor.
The Terminator 3 ASIC has hundreds of programmable registers for protocol con-
figuration, RFCs, and offload control. The S310E can offload TCP processing per-
connection, per-server, per-interface, and globally and simultaneously tunnel traf-
fic from non-offloaded connections to the host processor for the native TCP/IP
stack to process. The S310E provides a flexible zero copy capability for regular
TCP connections, requiring no changes to the sender, to deliver line rate perfor-
mance at minimal CPU utilization.

mance at minimal CPU utilization.
The S310E offloads the expensive byte touching iSCSI operations 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. The S310E also implements a high-capacity, low-
latency, high-bandwidth iWARP RDMA/RDDP, which adheres to the IETF stan-
dards.

Subjected to thousands of hours of compatibility testing, over two years of stress
testing by several OEM test suites and production deployments in servers, stor-
age systems and cluster computing, Chelsio’s robust, stable protocol offload tech-
nology delivers proven performance in a wide range of environments. The S310E
is generations ahead of competing products.
