iSCSI initiator is essential to the host side. It is controlling SCSI in an iSCSI implementation. Its role can
be played as either software or hardware (HBA). Please refer to the iSCSI HBA card list in Appendix A to
confi rm if your HBA card is supported. Initiator software adopts standard TCP/IP protocol and Ethernet
facilities while iSCSI HBA card uses vendor-proprietary iSCSI and TCP/IP protocols.
iSCSI HBA card vendors will provide proprietary initiator tools. Please refer to your HBA card user
manual for detailed information.
