: SCST 3.1 pre-release freeze
Hi All,
I'm glad to announce SCST 3.1 pre-release code freeze in the SCST SVN branch 3.0.x.
You can get it by command:
$ svn co https://scst.svn.sourceforge.net/svnroot/scst/branches/3.1.x
It is going to be released after few weeks of testing, if no significant issues found.
Highlights for this release:
- Cluster support for SCSI reservations. This feature is essential for initiator-side
clustering approaches based on persistent reservations, e.g. the quorum disk implementation in Windows Clustering.
- Full support for VAAI or vStorage API for Array Integration: Extended Copy command
support has been added as well as performance of WRITE SAME and of Atomic Test & Set, also known as COMPARE AND WRITE, has been improved.
- T10-PI support has been added.
- ALUA support has been improved: explicit ALUA (SET TARGET PORT GROUPS command) has
been added and DRBD compatibility has been improved.
- SCST events user space infrastructure has been added, so now SCST can notify a user
space agent about important internal and fabric events.
- QLogic target driver has been significantly improved.
SCST is alternative SCSI target stack for Linux. SCST allows creation of sophisticated storage devices, which can provide advanced functionality, like replication, thin provisioning, deduplication, high availability, automatic backup, etc. Majority of recently developed SAN appliances, especially higher end ones, are SCST based. It might well be that your favorite storage appliance running SCST in the firmware.
More info about SCST and its modules you can find on: http://scst.sourceforge.net
Thanks to all who made it happen, especially to SanDisk for the great support! All above highlights development was supported by SanDisk.

Hello Vlad
Excellent news on all the updates.
Regarding this:
- QLogic target driver has been significantly improved.Does that mean I should stop building the QLogic target driver from here?
git://git.qlogic.com/scst-qla2xxx.git<http://git.qlogic.com/scst-qla2xxx.git>Or are you saying the git.qlogic.com <http://git.qlogic.com> has been improved?
It is saying that qla2x00t was improved.
The ultimate goal is to have the mainstream (git) QLogic target driver to be the main and the only QLogic target driver, but, unfortunately, this driver not yet reached level of quality and maturity of qla2x00t. We with QLogic are working toward it.

If I stop building the one from git.qlogic.com <http://git.qlogic.com>, does the 3.2.0 one support NPIV?
Yes, it has full NPIV support.
