tasks from the host server or other computers connected to the LAN. To implement this capability, iSCSI servers must be upgraded with Ethernet NICs that include a TOE chip onboard. Although the selection of iSCSI TOE cards is generally limited to just a few manufacturers, it's important to consider the available ports, host interface, and other card characteristics before making a purchase. The product snapshots in this chapter highlight key specifications for a cross-section of popular iSCSI TOE cards. The following products were selected based on input from industry analysts and SearchStorage.com editors, and specifications are current as of February 2007.The following specifications have been provided by vendors and are periodically updated. Vendors are welcome to submit their updates and new product specifications to Matt Perkins.
