About iSCSI initiator and targets

iSCSI is a way to share storage over a network and works at the block device level. For iSCSI communication, the following components talk with each other:

  • Initiator

  • Target

The clients which access the iSCSI storage are called initiators. This iSCSI Initiator can connect to a server (the iSCSI target). In doing so, the iSCSI Initiator sends SCSI commands to the iSCSI target. These SCSI commands are packaged in IP packets for this purpose.

An iSCSI target device receives iSCSI commands and shares the storage. The storage can be a physical disk, or an area representing multiple disks or a portion of a physical disk. A storage array is a typical iSCSI target.
