context_page_description: In computing, Linux-IO Target is an open-source implementation of the SCSI target that has become the standard one included in the Linux kernel. Internally, LIO does not initiate sessions, but instead provides one or more Logical Unit Numbers, waits for SCSI commands from a SCSI initiator, and performs required input/output data transfers. LIO supports common storage fabrics, including FCoE, Fibre Channel, IEEE 1394, iSCSI, iSCSI Extensions for RDMA, SCSI RDMA Protocol and USB. It is included in most Linux distributions; native support for LIO in QEMU/KVM, libvirt, and OpenStack makes LIO also a storage option for cloud deployments.
  LIO is maintained by Datera, Inc., a Silicon Valley vendor of storage systems and software. On January 15, 2011, LIO SCSI target engine was merged into the Linux kernel mainline, in kernel version 2.6.38, which was released on March 14, 2011. Additional fabric modules have been merged into subsequent Linux releases.
  A competing generic SCSI target module for Linux is SCST. For the narrower purpose providing a Linux iSCSI target, the older IET and STGT modules also enjoy industry support.
context_section_description: The FireWire SBP-2 fabric module enables Linux to export local storage devices via IEEE 1394, so that other systems can mount them as an ordinary IEEE 1394 storage device.
  IEEE 1394 is a serial bus interface standard for high-speed communications and isochronous real-time data transfer. It was developed by Apple as "FireWire" in the late 1980s and early 1990s, and Macintosh computers have supported "FireWire target disk mode" since 1999.
  The FireWire SBP-2 fabric module was released with Linux 3.5 on July 21, 2012.
