You probably heard that Windows Storage Server 2008 R2 has been Released To Manufacturing (RTM) last week. What you might have missed is that Windows Storage Server 2008 R2 is also now available to MSDN and TechNet subscribers for evaluation. This means subscribers can now use Microsoft iSCSI Target 3.3 for Development, Test and all other non-production purposes. While this was also the case for Windows Storage Server 2008, this new R2 release allows you to install the iSCSI Target on any existing Windows Server 2008 R2 by simply installing an MSI (Microsoft Installer) file. That's much more convenient for Developers, Testers and IT Profressionals out there.
