Mastering Linux Storage Management The Power of LIO and TCM Passthru

LIO is a SCSI target framework integrated into the Linux kernel, providing a standardized interface for exporting storage devices over various ... TCMU (TCM in Userspace) allows userspace programs to be written which act as iSCSI targets. This document describes the design. TCM is another name for LinuxIO (LIO), an in-kernel iSCSI target (server). LIO is the standard open source multiprotocol SCSI target for Linux. The Linux-IO Target (LIO) is an open-source Small Computer System Interface (SCSI) target implementation included with the Linux kernel. LIO (LinuxIO) is the in-kernel iSCSI target (since Linux 2.6.38). Installation. The iSCSI target fabric is included since Linux 3.1. Multi-protocol in-kernel SCSI target. Unlike other targets like IET, tgt, and SCST,. LIO is entirely kernel code. LIO is the SCSI target in the Linux kernel. It is entirely kernel code, and allows exported SCSI logical units (LUNs) to be backed by regular files or block ... LIO, from recently being renamed to TCM, is another independent from SCST implementation of SCSI target framework for Linux.
