The target is the storage device itself or an appliance which controls and serves volumes
or virtual volumes. The target is the device which performs SCSI command or bridge to an
attached storage device.

The host side needs an iSCSI initiator. The initiator is a driver which handles the SCSI
traffic over iSCSI. The initiator can be software or hardware (HBA). Please refer to the
certification list of iSCSI HBA(s) in Appendix A. OS native initiators or other software
initiators use standard TCP/IP stack and Ethernet hardware, while iSCSI HBA(s) use their
own iSCSI and TCP/IP stacks on board.
Hardware iSCSI HBA(s) provide its own initiator tool. Please refer to the vendors’ HBA user
manual. Microsoft, Linux, Solaris and Mac provide iSCSI initiator driver. Please contact
QSAN for the latest certification list. Below are the available links:
