SCSI-3 Architecture and Commands - Online Class


This course provides the student with a comprehensive introduction to the Small Computer System Interface (SCSI-3) Architecture and Command language without getting bogged down with the details of the physical interface. It is intended for students that need an understanding of this pervasive command architecture that is used by a number of different physical interfaces including the SCSI Bus, Fibre Channel, iSCSI and Serial Attached SCSI (SAS).
