Details :WY5708F PCIe X4 Gigabit Fiber Server Adapter
The based on Broadcom TOE controller features an industry first support for single chip TOE Gigabit Ethernet NIC with TCP / IP offload Engine, RDMA NIC (RNIC)*, iSCSI 1.0* /iSER HBA*.
TCP Offload Engine
Include dedicated hardware and processors to process the frame that traverse it functionality. On the transmit path, the TOE controller Copied the data directly from the highest hierarchy of buffers available, execute the TCP/IP, adds lower level headers. On the receive, path, the TOE controller process frame up to the highest layer supported present in the frame, removes lower level headers, posts the data directly to application buffers. The transmit and the receive TOE functionality relieves the host CPI from the from these time consuming operations.
Convergence NIC
Enable convergence of all networked communication possible in a server, such as data network (LAN), storage network, or file ( CIFS / NFS), clustering for high performance commuting or inter process communication by support of RDMA* over TCP. The Silicom TOE server adapter is a convergence networking interface card and allows one network connection to provide access to all information types. Silicom TOE Gigabit Ethernet server adapters can simultaneously support the following functions:
• TOE Chimney- enabled network accelerator
• RDMA Network Interface Controller ( RNIC)*
• iSCSI or iSER Host Bus Adapter ( HBA) *
Reliability, Availability, Serviceability
Enables fault-tolerant via teaming. Traffic from the failed port is routed through up to seven other members of the team.
The ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.
