Yes, I know other systems use iSCIS, but I put this under Unix because it is the only system I work with when dealing with iSCSI

iSCSI is an excellent way of allowing one machine to access a volume over a network. Instead of a physical disk drive, the initiator connects to the target over a network and acquires a new block device ('disk drive'). This device can now be used in the same way a physical drive is.
