The iSCSI Target solution from MS is now free! We can use it to setup a environment to test fail-over clustering!
The Microsoft iSCSI Software Target has been available for production use as part of Windows Storage Server since early 2007. It has also been available for development and test use by MSDN and TechNet subscribers starting in May 2009. However, until now, there was no way to use the Microsoft iSCSI Software Target in production on a regular server running Windows Server 2008 R2. This new download offers exactly that.
Now available as a public download, the software is essentially the same software that ships with Windows Storage Server 2008 R2. Windows Storage Server 2008 R2 and the public download package will be refreshed (kept in sync) with any software fixes and updates. Those updates are described at http://technet.microsoft.com/en-us/library/gg232597.aspx.
This release was preceded by intense testing by the Microsoft iSCSI Target team, especially in scenarios where the iSCSI Target is used with Hyper-V and with Windows Server Failover Clusters. We do imagine these to be amongst the most commons deployment scenarios.
Testing included running the Microsoft iSCSI Software Target in a two-node Failover Cluster and configuring 92 individual Hyper-V VMs, each running a data intensive application and storing data on a single node of that iSCSI Target cluster. The exciting part of the test was to force an unplanned failure of the iSCSI Target node being used by all the VMs and verify that we had a successful failover to the other node with all 92 VMs continuing to run the application without any interruption.
