YES !!!

Microsoft is releasing the iSCSI Target Server and that means that you now can use a Windows Server 2008 R2 x64 OS as a SAN by adding this download, it is so cool!!!.

The Microsoft iSCSI Software Target 3.3 provides storage (disks) over a TCP/IP network. It turns a computer running Windows Server into a storage device which provides shared block storage. You can use Microsoft iSCSI Software Target 3.3 to perform a variety of storage-related tasks, including the following:

• Provide shared storage for Hyper-V to enable high availability and live migration
• Consolidate storage for multiple application servers (i.e. Microsoft SQL Server or Hyper-V)
• Provide shared storage for applications hosted on a Windows failover cluster
• Enable diskless computers to boot remotely from a single operating system image using iSCSI

The Microsoft iSCSI Software Target 3.3 is an economical solution suited for a development or test environment and a small, medium, or branch office production environment. It enables storage consolidation and sharing on a Windows Server by implementing the iSCSI (Internet Small Computer Systems Interface) protocol, which supports SCSI-block access to a storage device over a TCP/IP network.
