| Term | Description |

Logical Unit |
A logical unit is a component of a storage system. A logical unit is uniquely numbered creating a Logical Unit Number (LUN). The storage appliance can contain many LUNs. LUNs when associated with one or more SCSI targets, form a unique SCSI device. This SCSI device can be accessed by one or more SCSI initiators. |
|
Initiator |
An initiator is an application or production system end-point that is capable of initiating a SCSI session, sending SCSI commands, and I/O requests. Initiators are also identified by unique addressing methods. |
|
Initiator Group |
A set of initiators. When an initiator group is associated with a LUN, only initiators from that group may access the LUN. |
|
Target |
A target is an end-point that provides a service of processing SCSI commands and I/O requests from an initiator. A target, once configured, consists of zero or more logical units. |
|
Target Group |
A set of targets. LUNs are exported over all the targets in one specific target group. |
