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.
CDemu is a free and open-source virtual drive software, designed to emulate an optical drive and optical disc (including CD-ROMs and DVD-ROMs) on the Linux operating system.. As of 30 June 2019, CDemu is not available in the official repositories of Debian, Ubuntu and Fedora Linux for any release, but it is available via official PPA for Ubuntu and COPR for Fedora Linux.
On a parallel SCSI bus, a device (e.g. host adapter, disk drive) is identified by a "SCSI ID", which is a number in the range 0–7 on a narrow bus and in the range 0–15 on a wide bus. On earlier models a physical jumper or switch controls the SCSI ID of the initiator (host adapter).
VirtualBox may be installed on Microsoft Windows, macOS, Linux, Solaris and OpenSolaris. There are also ports to FreeBSD [5] and Genode. [6] It supports the creation and management of guest virtual machines running Windows, Linux, BSD, OS/2, Solaris, Haiku, and OSx86, [7] as well as limited virtualization of macOS guests on Apple hardware.
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 ...
All target driver and storage driver functions invoked by the SCST core are asynchronous, at least when the Linux kernel allows this. It is e.g. not yet possible to perform asynchronous or direct I/O from inside the Linux kernel. [13] One finite-state machine is associated with each SCSI command. This allows a single command thread to process ...
On those systems, the ASPI interface is designed for applications which require SCSI pass-through functionality (such as CD-ROM burning software). [1]: 57 The primary operations supported by ASPI are discovery of host adapters and attached devices, and submitting SCSI commands to devices via SRBs (SCSI Request Blocks).
SCSI / ATA Translation (SAT) is a set of standards developed by the T10 subcommittee, defining how to communicate with ATA devices through a SCSI application layer. The standard attempts to be consistent with the SCSI architectural model , the SCSI Primary Commands, and the SCSI Block Commands standards.
