Intel I340 Ethernet Dual Port and Quad Port Server Adapters for IBM System x Based on the new Intel® 82580 Gigabit Ethernet Controller, the Intel Ethernet Dual Port and Quad Port Server Adapters for IBM® System x® are Intel's fourth generation of PCI Express Gigabit Ethernet (PCIe GbE) adapters. These adapters showcase the industry's first fully integrated, multi-port PCIe 2.0 GbE controllers, providing a smaller footprint and lower power dissipation. In addition, these adapters offer advanced features, including support for multi-core processors and server virtualization, as well as a scalable PCI Express 2.0 interface. Intel's first eco-friendly, halogen-free design combines low power use and low cost for one of the best price to performance ratios in a multi-port solution that is available today. Figure 1 shows the Intel Ethernet Quad Port Server Adapter. The adapters have the following features: Two or four 10/100/1000 copper ports with RJ45 for Cat 5e/6 cabling Based on Intel 82580 ASIC (quad-port MAC/PHY controller) PCIe 2.0 x4 host interface Low-profile card form factor Wake on LAN support Preboot eXecution Environment (PXE) boot support VLAN support with VLAN tag insertion, stripping, and packet filtering for up to 4096 VLAN tags iSCSI boot support (built-in software iSCSI initiator) iSCSI support with native operating system initiators Jumbo frame support Intel I/O Acceleration Technology (I/OAT) acceleration Intel Virtual Machine Device Queues (VMDq) support for VMware with eight queues per port TCP/IP checksum offload TCP/IP segmentation offload / large-send offload support
