  • c66ac9db8   [SCSI] target: Add LIO target core v4.0.0-rc6 ... Browse Code ยป

    LIO target is a full featured in-kernel target framework with the
    following feature set:

    High-performance, non-blocking, multithreaded architecture with SIMD
    support.

    Advanced SCSI feature set:

    * Persistent Reservations (PRs)
    * Asymmetric Logical Unit Assignment (ALUA)
    * Protocol and intra-nexus multiplexing, load-balancing and failover (MC/S)
    * Full Error Recovery (ERL=0,1,2)
    * Active/active task migration and session continuation (ERL=2)
    * Thin LUN provisioning (UNMAP and WRITE_SAMExx)

    Multiprotocol target plugins

    Storage media independence:

    * Virtualization of all storage media; transparent mapping of IO to LUNs
    * No hard limits on number of LUNs per Target; maximum LUN size ~750 TB
    * Backstores: SATA, SAS, SCSI, BluRay, DVD, FLASH, USB, ramdisk, etc.

    Standards compliance:

    * Full compliance with IETF (RFC 3720)
    * Full implementation of SPC-4 PRs and ALUA

    Significant code cleanups done by Christoph Hellwig.

    [jejb: fix up for new block bdev exclusive interface. Minor fixes from
    Randy Dunlap and Dan Carpenter.]
