%description
A generic SCSI target subsystem for Linux that allows to convert any Linux
server into a sophisticated storage server. The three layers in SCST are the
target driver layer; the SCSI target core and the device handler layer. SCST
target drivers realize communication with an initiator and implement a storage
protocol like iSCSI, FC or SRP. SCST device handlers implement a SCSI
interface on top of local storage. Examples of such local storage are SCSI
RAID controller (dev_disk handler), block device (vdisk_blockio handler), file
(vdisk_fileio handler) or custom block device behavior implemented in user
space (scst_user).

A generic SCSI target subsystem for Linux (SCST) that allows to convert
any Linux server into a sophisticated storage server. SCST target drivers
implement protocols like iSCSI, FC or SRP. SCST device handlers either
provide access to a local SCSI RAID controller (dev_disk), block device
(vdisk_blockio), file (vdisk_fileio) or custom block device behavior
implemented in user space (scst_user).
