The MIC-5203 is a low power, quad-port GbE AMC, with copper RJ-45 or fiber SFP pluggable modules. It incorporates the Intel® 82580 Quad Gigabit Ethernet controller. The AMC provides a high performance PCIe x4 interface at 5 Gb/s per lane at an outstanding low power dissipation of less than 10W. Support for Intel’s offloading and platform enhancement features yields maximum network throughput while preserving valuable CPU cycles for application processing. The MIC-5203 features an Intel®82580 which provides Intel® Virtualization Technology for Connectivity (VT-c) and Virtual Machine Device Queues (VMDq), helping to reduce I/O bottlenecks, boost throughput, and reduce latency. Where virtualization is required, VMDq improves performance by offloading the data-sorting burden from the virtual machine manager (VMM) to the network controller. The MIC-5203’s specialized features include VLAN tagging, stripping and packet filtering; iSCSI, UDP, TCP and IP Checksum offload. For a maximum of interoperability, the MIC-5203 supports a PCIex4 (AMC Ports 4..7) host interface. The PCIe reference clock can be supplied over FLCKA or an onboard oscillator for systems which do not supply a PCIe reference clock. The MIC-5203 is compliant with both AMC.0 R1.0 and R2.0 specifications.
