GlobalSAN iSCSI initiator is a network protocol standard that enables the transport of block-level I/O over TCP/IP. When deployed over a Gigabit or 10-Gigabit Ethernet network, an iSCSI-based storage area network (SAN) can rival the performance of a Fibre Channel SAN, and can cost far less to implement. In an iSCSI SAN, an initiator is needed for each computer that requires access to the networked storage.
