Chelsio T520-BT - Network adapter - PCIe 3.0 x8 - 10Gb Ethernet x 2 MPN:T520-BT

Software/drivers. Chelsio offers a full suite of protocol software drivers with the T520-BT adapters. The software supports operation in both protocol-offload and non-offload modes. Fifth-generation protocol offload engine. The T5 is Chelsios fifth-generation TCP offload (TOE) design, fourth-generation iSCSI design, and third-generation iWARP (RDMA) implementation. With support for the 8 Gbps Gen 3 data rate, the T5 ASIC PCIe interface provides 64 Gbps of raw bandwidth to the server. T5 also provides support for PCIe SR-IOV virtualization with embedded virtual switch. Packet switching and routing. T520-BT integrates a high performance packet switch, which allows switching traffic from any of the input ports to any of the output ports (wire-to-wire) and from any of the output ports to any of the input ports (host-to-host). The unified wire solution. The T5 ASIC enables a unified wire for LAN, SAN, and cluster traffic, built upon a combination of high bandwidth and low latency architecture along with a complete set of storage and cluster protocols operating over Ethernet (iSCSI, FCoE, and iWARP). In parallel, operating systems and hypervisors that have incorporated native support for iSCSI and database applications are now supporting file-based storage protocols such as NFS as an alternative to SANs. FCoE and iSCSI support in the T520-BT benefits from high reliability features that include memory ECC, data path CRC and T10-DIX in addition to the checksums and CRC available at different protocols layers. iSCSI and FCoE provide a transition path from legacy SANs to converged networks. Robust, proven solution. Subjected to thousands of hours of compatibility testing, over a decade of stress testing by several OEM test suites and production deployment in servers, storage systems, and cluster computing, Chelsios robust, stable protocol offload technology delivers proven performance in a wide range of environments. Complete and flexible TCP offload. The T5 has hundreds of programmable registers for protocol configurations, RFCs, and offload control. The T520-BT can offload 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. The T520-BT provides a flexible zero-copy capability for regular TCP connections, requiring no changes to the sender.
