LREC9712PT PCI Express x4DualPortCopper Gigabit Server Adapter (Broadcom 5709C Based)

 

Description

LR-LINK LREC9712PT PCI Express TOE server adapters are network interface cards that contain single/multiple independent Gigabit Ethernet port/s. The PCI Express TOE server adapters provide a fully integrated up to Layer 5 solution along with a complete Gigabit Ethernet port/s.

 

LR-LINK LREC9712PT Gigabit Ethernet PCI Express TOE server adapter is a high performance server network application. LR-LINK LREC9712PT Gigabit Ethernet PCI Express TOE server adapters are 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)*, iSCSI1.0*/iSER HBA*.

 

TCP Offload Engine

The LR-LINK LREC9712PT TOE server adapters 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 these time consuming operations.

 

Convergence NIC

The LR-LINK LREC9712PT Gigabit Ethernet PCI Express TOE server adapters 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 LR-LINK LREC9712PT TOE server adapter is a convergence networking interface card and allows one network connection to provide access to all information types. LR-LINK LREC9712PT 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

LR-LINK LREC9712PT Gigabit Ethernet PCI Express TOE server adapters enables fault-tolerant via teaming. Traffic from the failed port is routed through up to seven other members of the team.

LR-LINK LREC9712PT Gigabit Ethernet PCI Express TOE server adapters are the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.

 

Key Features
