Generic SCSI Target Subsystem For Linux / News: Recent posts

SCSI target middle level for Linux version 0.9.5 and Qlogic 2x00 target driver for 2.6 kernels version 0.9.5 released.

This version of SCST is a major improvement in almost all areas.

SCST development repository switched from CVS to SVN on SF.net. You can access it using:

svn co https://svn.sourceforge.net/svnroot/scst

The commit notifications will be sent in scst-svn mailing list.

The CVS is read-only now and indended only for history keeping.

SCSI target middle level for Linux version 0.9.4 and Qlogic 2x00 target driver for 2.6 kernels version 0.9.3.8 released.

Also released SCST 0.9.3.1-24 with 2.4 kernels support.

There are mostly stability fixes and cleanups in all modules.

There are mostly stability fixes and cleanups. Both modules are more or less stable now.

There are mostly stability fixes and cleanups. The interface with target drivers was changed and made more simple and reliable.

Target drivers for Adaptec 7xxx, LSI/MPT and Qlogic QLA12xx available for download from http://bj.soulinfo.com/~hugang/scst/tgt/, thanks to Hu Gang. These drivers are not completed, but looks to be a good starting point. SCST team don't have the appropriate hardware, therefore have not tested and don't support them. Send all questions to Hu Gang <hugang % soulinfo.com>.

Basically, SCST 0.9.3-pre2 has many bug fixes as well as many changes that intended to provide stable high performance under extreme loads.

Qlogic 2x00 SCSI target driver 0.9.3.2 has only cosmetic compilation fixes for the latest kernels and gcc.

Two main features added in this release:

- Support for 2.6 kernels

- Ability to work with SCST (Generic SCSI Target Middle Level for Linux) 0.9.2, so now it is possible to use its FILEIO/BLKDEV device handler.

Generic SCSI Target Middle Level for Linux (SCST) version 0.9.2 released and available for download. The major changes from version 0.9.1 are

- 2.6 kernels support

- FILEIO/BLKDEV device handler that works over files on file system and
makes from them virtual remotely available SCSI disks. In addition, it
allows to work directly over a block device, e.g. local IDE or SCSI disk
or ever disk partition, where there is no file systems overhead. Using
block devices comparing to sending SCSI commands directly to SCSI
mid-level via scsi_do_req() has advantage that data are get or put via
system cache, so it can fully benefit from caching and read ahead,
performed by Linux's VM subsystem.

The first public release 0.9.1 of a generic SCSI target middle level subsystem for Linux (SCST) is available for download together with Qlogic 2200/2300 target driver and a patch for for UNH-iSCSI Target 1.5.3 to work over SCST. SCST is designed to provide unified, consistent interface between SCSI target drivers and Linux kernel and simplify target drivers development as much as possible. It has a lot of features, including high performance and scalability, complete SMP support, required SCSI functionality emulation.
