[Acronym] for InterNet [SCSI]. iSCSI is a method of encapsulating SCSI over [TCP]/[IP]. It is defined in RFC:3720, An end user will send a request for some data. The OperatingSystem will generate SCSI commands and a data request, which are then encapsulated and encrypted by the iSCSI driver (the ''initiator''). A packet header is added and the IP packets are transmitted over the [Ethernet]. An iSCSI device receives the packet, decrypts and disassembles it, separating the SCSI commands and request. The SCSI commands are sent through the SCSI controller to the SCSI device (the ''target''). Data will be retreived and returned in the same fashion. Unlike [NAS], iSCSI makes block devices available via the network. You access the disc as if it was mounted locally, and can use any FileSystem of your choice. However, because it is being handled as a block device, only one system can use the iSCSI device at a time. To get around this you will need to use a global or read-only FileSystem. iSCSI has gained popularity over FibreChannel over IP (FCIP) because it can run over standard Ethernet networks.
