HELSIO’S R310E 10GbE
iWARP Adapter is a pro-
C
tocol-offloading 10 Gigabit
Ethernet adapter with PCI
Express host bus interface for
servers and storage systems.
The third-generation technology from Chelsio provides the
highest 10GbE performance
available and dramatically lowers host-system CPU communications overhead.
With on-board hardware that offloads iWARP RDMA processing from its
host system, the R310E frees up host CPU cycles for useful applications.
The system gets increased bandwidth, improved overall performance,
and reduced message latency across allapplications.
This combination makes it practical to converge other networks that traditionally used niche technologies onto 10GbE. High bandwidth and
extremely low latency make 10GbE the best technology for highperformance cluster computing(HPCC) fabrics.
Benefits
By using Chelsio’s R310E, enterprises can cost-effectively connect servers and storage systems directly to the 10GbE backbone over lower-cost
CX4 copper oractive optical cabling and switching infrastructure.
As an upgrade or alternative to aggregated Gigabit Ethernet links, 10GbE
boosts connection bandwidth and simplifies cabling, installation, and maintenance. The R310E also provides additional bandwidth needed to consolidate server functions on fewer, more powerful systems – simplifying
management and reducing costs for servers, rackspace, power consumption, and maintenance.
Applications with largedata sets benefit from a high-speed distributedplatform, including video rendering and distribution, data visualization such as
remote medical imaging and climatic modeling, and bioinformatics applications such asDNAsequencing.

Specifications
The R310E offers best-of-class performance and features, including
IP/UDP/TCP checksum and large send offload, rate control and QoS,
virtualization, and rule-basedtraffic steering and filtering.
Third-Generation Protocol Offload Engine
The R310E 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 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 bythe performance of each processor.
Upper Layer Protocols
The R310E implements a high-capacity, low-latency, high-bandwidth
iWARP RDMA/RDDP, which adheres to the IETF standards. It can
also run existing unmodified InfiniBand RDMA applications with lower
latency and higherbandwidth.
Robust, Proven Solution
Subjected to thousands of hours of compatibility testing, over two
years of stress testing by several OEM test suites and production
deployments in servers, storage systems and cluster computing,
Chelsio’s robust, stable protocol offload technology delivers proven
performance in a wide range of environments. The S310E is generations ahead ofcompeting products.
Software Drivers
Chelsio offers a full suite of protocol software and drivers for Linux and
Windows with the R310E adapter. The software supports operation in
both protocol-offload and non-offload modes.
