  2. LIO (SCSI target) - Wikipedia

    en.wikipedia.org/wiki/LIO_(SCSI_target)

    The Linux-IO Target (LIO) is an open-source Small Computer System Interface (SCSI) target implementation included with the Linux kernel. [ 1 ] [ better source needed ] 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 ...

  3. SCSI architectural model - Wikipedia

    en.wikipedia.org/wiki/SCSI_Architectural_Model

    The client is called a SCSI initiator and the server is called a SCSI target. A SCSI domain consists of at least one SCSI device, at least one SCSI target and at least one SCSI initiator interconnected by a service delivery subsystem. A SCSI device has one or more SCSI ports, and a SCSI port may have an optional SCSI port identifier (SCSI ID or ...

  4. SCST - Wikipedia

    en.wikipedia.org/wiki/SCST

    The number of threads per storage device that processes SCSI commands is configurable. 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]

  5. SCSI - Wikipedia

    en.wikipedia.org/wiki/SCSI

    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 ...

  6. Logical unit number - Wikipedia

    en.wikipedia.org/wiki/Logical_unit_number

    From the computer perspective, SCSI LUN is only a part of the full SCSI address. The full device's address is made from the: c-part: controller ID of the host bus adapter, t-part: target ID identifying the SCSI target on that controller, d-part: disk ID identifying a LUN on that target, s-part: slice ID identifying a specific partition on that ...

  7. SCSI initiator and target - Wikipedia

    en.wikipedia.org/wiki/SCSI_initiator_and_target

    As in a client–server architecture, an initiator is analogous to the client, and a target is analogous to the server. Each SCSI address (each identifier on a SCSI bus) displays behavior of initiator, target, or (rarely) both at the same time. There is nothing in the SCSI protocol that prevents an initiator from acting as a target or vice versa.

  8. World Wide Name - Wikipedia

    en.wikipedia.org/wiki/World_Wide_Name

    A WWN may be employed in a variety of roles, such as a serial number or for addressability; for example, in Fibre Channel networks, a WWN may be used as a WWNN (World Wide Node Name) to identify an endpoint, or a WWPN (World Wide Port Name) to identify an individual port on a switch. Two WWNs which do not refer to the same thing should always ...

  9. SCSI RDMA Protocol - Wikipedia

    en.wikipedia.org/wiki/SCSI_RDMA_Protocol

    In computing the SCSI RDMA Protocol (SRP) is a protocol that allows one computer to access SCSI devices attached to another computer via remote direct memory access (RDMA). [1] [2] The SRP protocol is also known as the SCSI Remote Protocol. The use of RDMA makes higher throughput and lower latency possible than what is generally available ...
