SINGLE-PORT 1000/2500BASE-X ETHERNET CONTROLLER WITH INTEGRATED TCP OFFLOAD ENGINE, RDMA, iSCSI WITH PCI EXPRESS®
The BCM5708S provides a fully integrated Layer 4 and Layer 5 solution – TCP/IP, RDMA, and iSCSI along with a complete 1000/2500BASE-X Gigabit Ethernet, IEEE 802.3 compliant Media Access Control (MAC), and Physical Layer Transceiver solution for high performance network applications. By itself, the BCM5708S provides a complete single-chip Gigabit Ethernet NIC with a TCP/IP Offload Engine, RDMA NIC (RNIC), iSCSI HBA, or LOM solution.
