By itself, the BCM5708C provides a complete single-chip GbE NIC with a TCP/IP processing engine, RDMA NIC (RNIC), iSCSI 1.0 HBA, or LOM solution. The BCM5708C is different from other network controllers because it can process the TCP/IP and relevant L5 protocols on data directly from the application buffers on the host, thereby relieving the host CPU from these time-consuming operations. On the receive path, the BCM5708C processes the frame up to the highest layer supported present. For example, the BCM5708C processes the frame for RDMA when the frame is an RDMA frame. Target Applications of the BCM5708C • GbE NICs and LOM • iSCSI 1.0 HBA • RNIC Network Interface Cards (NIC) Designs 10/1001000BASE-T PCI Express x4 NIC LAN on Motherboard (LOM) Designs 10/1001000BASE-T PCI Express x4, x2, or x1 LOM With the appropriate configuration, the BCM5708C can simultaneously support the following three functions: • RNIC • iSCSI host bus adapter (HBA) • TOE chimney-enabled network accelerator Broadcom®, the pulse logo, Connecting everything®, the Connecting everything logo, FASTPATH®, and NetXtreme II® are among the trademarks of Broadcom Corporation and/or its affiliates in the United States, certain other countries and/or the EU.
