Recently during one of my Windows Failover clustering presentation I received the question how to emulate iSCSI shared disks to build a failover cluster without having to buy an expensive storage environment. In my case I'm using our own iSCSI target software but there are some other vendors that let you use their target software for free:
MySAN, from Nimbus Data Systems: http://www.nimbusdata.com/products/mysan/mysan.htm StarWind, from RocketDivision: http://www.rocketdivision.com/download_starwind.html
Now you have all the tools needed to start testing out Windows Server 2008 failover clustering.
PingBack from http://msft.starsports.info/msft/free-iscsi-target-software/
In my tests, MySAN doesn't support Windows clustering - it won't pass the validation tests, because it doesn't support some features such as SCSI-3 persistent reservations. Have I missed something? I have not yet had a chance to test StarWind.
It would be nice if Microsoft provided an iSCSI target (like WinTarget from StringBean, which was acquired last year,) without requiring customers to purchase Windows Storage Server.
Indeed StarWind iSCSI Target from Rocket Division Software does fully support
both 2003 style clustering and new 2008 style clustering (with the persistant
reservations). Just in case here's an URL:

At the same time referenced MySan does not work at all.,,,,,,

There also have a free version.
There also have a free version of iSCSI Target.
If you are an MSDN or TechNet Plus subscriber, you can get Windows Storage Server 2008 and the Microsoft iSCSI Software Target 3.2: http://blogs.technet.com/josebda/archive/2009/05/16/windows-storage-server-2008-with-the-microsoft-iscsi-software-target-3-2-available-to-msdn-and-technet-plus-subscribers.aspx
Starwind iSCSI target enables High-Availability with ESX and Hyper-V and is now availible for free at http://www.starwindsoftware.com/free
StarWind can provide High Availability itself.
StarWind iSCSI target is completely free, SCSI-3 PR compatible, vendor agnostic and highly available:
You can use it in standalone environment. If you want to build a clustered iSCSI Target environment here are my notes; techontip.wordpress.com/.../microsoft-iscsi-target-cluster-building-walkthrough
