S320EM-BCH
CHELSIO’SS320EM-BCH 10GbE Storage Accelerator is a dual-port
10 Gigabit Ethernet mezzanine card with PCI Express host bus inter-
face for IBM BladeCenter H, optimized for storage applications. The third-
generation technology from Chelsio provides the highest 10GbE perfor-
mance available and dramatically lowers host-system CPU communica-
tions overhead.
With on-board hard-
ware that offloads
TCP/IP, iSCSI, and
iWARP RDMA pro-
cessing from its host
system, the S320EM-
BCH frees up host
CPU cycles for useful
applications. The sys-
tem achieves
increased bandwidth,
lower latency, and
lower power.
This combination makes it practical to converge other networks that tradi-
tionally used niche technologies onto 10GbE. High bandwidth and
extremely low latency make 10GbE with protocol offload the best technol-
ogy for high-performance cluster computing (HPCC) fabrics.
The S320EM-BCH also accelerates the iSCSI protocol for block-level stor-
age traffic between servers and storage systems. With high-speed iSCSI,
10GbE is now the best technology for storage area networks. For more
info on Chelsio’s iSCSI solution, please go to our website at
www.chelsio.com.
The adapter’s two ports and IEEE 802.3ad link aggregation/failover fea-
tures are ideal for critical network applications that require redundancy
and high-availability capabilities.
With the S320EM-BCH, Chelsio is delivering on the promise of the ‘unified
wire,’ enabling the convergence of server networking, storage networking,
and cluster computing interconnects onto a single platform and a single
fabric.
10Gb Ethernet-only networking reduces the data center’s cost in network
adapters, cables, switches, rack space, power, equipment spares, man-
agement tools, planning, networking skills, and installation.

The dual-port S320EM-BCH 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.
The S320EM-BCH employs Chelsio’s unique third-generation Terminator 3
ASIC, a high-performance, programmable protocol processor. Terminator 3
processes all connections in a single datapath to deliver line-rate 10Gbps per-
formance with one connection, up to thousands of connections. In contrast,
competitive multi-RISC offload engines, which rely on having enough con-
nections to distribute their processing among parallel processors to achieve
full performance, are ultimately limited by the performance of each processor.
The Terminator 3 ASIC has hundreds of programmable registers for protocol
configuration, RFCs, and offload control. The S320EM-BCH can offload TCP
processing per-connection, per-server, per-interface, and globally and simul-
taneously tunnel traffic from non-offloaded connections to the host processor
for the native TCP/IP stack to process. The S320EM-BCH 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.
The S320EM-BCH 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 S320EM-
BCH also implements 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 two 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. The S320EM-BCH is generations ahead of competing products.
Chelsio offers a full suite of protocol software and drivers for Linux and
Windows with the S320EM-BCH adapter. The software supports operation in
both protocol-offload and non-offload modes.
