Anatomy of the Linux SCSI subsystem

The Small Computer Systems Interface (SCSI) is a collection of standards that define the interface and protocols for communicating with a large number of devices (predominantly storage related). Linux® provides a SCSI subsystem to permit communication with these devices. Linux is a great example of a layered architecture that joins high-level drivers, such as disk or CD-ROM drivers, to a physical interface such as Fibre Channel or Serial Attached SCSI (SAS). This article introduces you to the Linux SCSI subsystem and discusses where this subsystem is going in the future.
