Hi All,

I'm glad to announce a merge of support of 4/8Gb (24xx/25xx) QLogic HBA's in SCST target driver qla2x00t v2.0.

Throughout the last three years ID7 and I have been working on an enterprise class Fibre Channel target based on the QLogic range of 4/8Gb HBA's. This has been solely funded by ID7 over the last years however given the positive contributions by many of the SCST community both personal and commercial, ID7 have chosen to merge with existing QLogic's open source driver qla2x00t and introduce the driver under GPL license for community use.

This driver was designed from ground up to perform at the highest of levels and interoperate with leading infrastructures, accordingly the design and flow is much more focused and structured whilst the stability is as you would expect at the Enterprise level.

Although there is a current QLogic target driver qla_isp, this driver has the key advantage that it was designed to be as simple as possible. As the result, this driver is a lot smaller, cleaner and mainline Linux kernel ready. After some cosmetic cleanups it's going to be pushed for the in-kernel inclusion together other SCST patches.

Another advantage is that this driver fully supports FC tapes, including transport level retries on data delivery problems.

At the moment qla2x00t v2.0 is available only from the SCST SVN trunk. You can download it by command:

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

You can always find the latest info about qla2x00t driver from its page http://scst.sourceforge.net/target_qla2x0t.html.

Once again we are grateful for all the positive work and contributions and hopeful that this target helps drive SCST further forward as an Enterprise class target. We encourage people to introduce and evaluate this target driver.
