A target device could end up being a difficult disk or a disk array system. Typically wires connecting an initiator and target with or withóut expanders and backpIanes constitute a provider delivery subsystem.

Each SAS interface in a SAS domains has a SCSI port identifier that identifies the interface distinctively within the SAS website, the Entire world Wide Title. It can be assigned by the gadget manufacturer, like an Ethernet devices MAC deal with, and is certainly typically world-wide special as nicely. SAS products make use of these opening identifiers to deal with communications to each other. One doesnt often see these device titles because the slot identifiers tend to identify the gadget sufficiently. People occasionally direct to a SCSI port identifier as the SAS address of a gadget, out of dilemma. People occasionally contact a SAS address a Entire world Wide Name or WWN, because it is certainly basically the same matter as a WWN in Fiber Channel.
