IO LIO has been the Linux SCSI target since kernel version 2. It supports a rapidly growing number of fabric modules, and all existing Linux block devices as backstores. Overview Linux. IO is based on a SCSI engine that implements the semantics of a SCSI target as described in the SCSI Architecture Model SAM, and supports its comprehensive SPC 3SPC 4 feature set in a fabric agnostic way. The SCSI target core does not directly communicate with initiators and it does not directly access data on disk. LIO has obtained VMware v. Sphere 4 Ready certification on Buffalo PDF and QNAP PDF systems, and v. Sphere 5 Ready certification on Netgear PDF and Pure Storage PDF systems. Native support in Open. Stack setup, code, starting with the Grizzly release, makes LIO also an attractive storage option for cloud deployments. The LIO core targetcore. Linux kernel driver database was released with Linux kernel 2. January 1. 4, 2. 01. Setup targetcli provides a comprehensive, powerful and easy CLI tool to configure and manage LIO. Datera. Fabric modules Fabric modules implement the frontend of the SCSI target. They speak specific protocols that transport SCSI commands.

It supports a rapidly growing number of fabric modules, and all existing Linux block devices. The Fabric Hardware Abstraction Layer F HAL allows all protocol specific processing to be encapsulated in fabric modules. The following fabric modules are available. Fibre Channel SCSI access over FC networks with QLogic. Brainboxes 1 Port RS232 USB to Serial Adapter US101 USB to Serial adapter providing one RS232 serial port. Data transfer rates up to 921,600 baud rates and the 128. Arch Linux is an independently developed i686x8664 optimized community distribution, based on a rollingrelease package model and targeted at competent GNULinux. Compares Linux distributions major, minor, regional in simple table format. Information such as price, support, documentation, included packages.

They implement the methods of accessing data on disk. A backstore subsystem plugin is a physical storage object that provides the block device underlying a SCSI Endpoint. Backstore objects can be added via the Storage Hardware Abstraction Layer S HAL that brings storage hardware into LIO engine as raw block devices, on which the Linux stack just works including complex functionality such as software RAID, LVM, snapshots, virtualization, etc. LIO supports the SCSI 3 standard for all backstore devices block devices andor VFS. FILEIO Linux VFS devices any file on a mounted filesystem. It may be backed by a file or an underlying real block device. FILEIO is using struct file to serve block IO with various methods synchronous or asynchronous and buffered or direct. The Linux kernel code for filesystems resides in linuxfs. By default, FILEIO uses non buffered mode OSYNC set. IBLOCK Linux BLOCK devices any block device that appears in sysblock. The Linux kernel code for block devices is in linuxblock. PSCSI Linux pass through SCSI devices any storage object that supports direct pass through of SCSI commands without SCSI emulation. This assumes an underlying SCSI device that appears with lsscsi in procscsiscsi, such as a SAS hard drive, etc. SCSI 3 and higher is supported with this subsystem, but only for control CDBs capable by the device firmware. Memory Copy RAMDISK Linux RAMDISKMCP Memory Copy ram disks rdmcp provide ram disks with full SCSI emulation and separate memory mappings using memory copy for initiators, thus providing multi session capability. This is most useful for fast volatile mass storage for production. SCSI functionality is implemented directly in the LIO engine in a fabric agnostic way, including a number of high end features, such as Persistent Reservations PRs, Asymmetric Logical Unit Assignment ALUA, v. Storage APIs for Array Integration VAAI following the SPC 4 standard. The backstore devices FILEIO, IBLOCK, p. SCSI, RAMDISK, etc. HW limitiations for things like TCQ depth, Max. Sectors, Task. Aborted. Status, UA Interlocking, etc. All of these values are available as attributes in the targetcli device context. Specifications The following specifications are available as T1.

Command Descriptor Block CDB The standard format for SCSI commands. CDBs are commonly 6, 1. Challenge Handshake Authentication Protocol CHAP An authentication technique for confirming the identity of one computer to another. Described in RFC 1. Connection Identifier CID A 1. Initiator, that uniquely identifies a connection between two i. SCSI devices. This number is presented during the login phase. Endpoint The combination of an i. SCSI Target. Name with an i. SCSI TPG Tag IQN Tag. Converged Network Adapter CNA An Ethernet PCIe network adapter NIC that natively supports RDMA via Ro. CE, also called RNIC. Demo Mode Means disabling authentification for an i. SCSI Endpoint, i. ACLs are diabled. Demo Mode grants read only access to all i. SCSI Initiators that attempt to connect to that specific Endpoint. See the i. SCSI entry on how to enable Demo Mode.
