The IBM POWER virtual SCSI client driver for Linux (ibmvscsi), available since January 2008 (kernel version 2.6.24 [11]). Virtual SCSI allows client logical partitions to access I/O devices (disk, CD, and tape) that are owned by another logical partition. [12] [13] The following SRP target implementations exist: The SCST SRP target ...
Adaptec also developed generic SCSI disk and CD-ROM drivers for DOS (ASPICD.SYS and ASPIDISK.SYS). [3]: 60–61 At least a couple of other programming interfaces for SCSI device drivers competed with ASPI in the early 1990s, including CAM (Common Access Method), developed by Apple; and Layered Device Driver Architecture, developed by Microsoft.
The storage port drivers provide an interface for Win32 applications to send SCSI Command Descriptor Block (CDB) messages to SCSI devices. The interfaces are IOCTL_SCSI_PASS_THROUGH and IOCTL_SCSI_PASS_THROUGH_DIRECT. Applications can build a pass-through request and send it to the device by using this IOCTL.

SCSI Pass Through Direct (SPTD) is a proprietary device driver and application programming interface (API) that provides a method of access to SCSI storage devices. Originally developed in 2004 by Duplex Secure Ltd., it is now owned and maintained by Disc Soft Ltd., [1] the developer of Daemon Tools.
SCSI was introduced in the 1980s and has seen widespread use on servers and high-end workstations, with new SCSI standards being published as recently as SAS-4 in 2017. The SCSI standards define commands, protocols, electrical, optical and logical interfaces. The SCSI standard defines command sets for specific peripheral device types; the ...
The Linux-IO Target (LIO) is an open-source Small Computer System Interface (SCSI) target implementation included with the Linux kernel. [1]Unlike initiators, which begin sessions, LIO functions as a target, presenting one or more Logical Unit Numbers (LUNs) to a SCSI initiator, receiving SCSI commands, and managing the input/output data transfers.
Virtual devices may also operate in a non-virtualized environment. For example, a virtual network adapter is used with a virtual private network, while a virtual disk device is used with iSCSI. A good example for virtual device drivers can be Daemon Tools. There are several variants of virtual device drivers, such as VxDs, VLMs, and VDDs.
