Fully Featured Server Adapter

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-based traffic 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 process- ing among parallel processors to achieve full performance, are ulti- mately limited by the 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 higher bandwidth.

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 genera- tions ahead of competing 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.
