		Microsoft  released  on Monday iSCSI Software Target 3.3, a Windows Server 2008  R2 addition that allows for shared block storage in storage area networks using the iSCSI  protocol.
According to Microsoft's  announcement, iSCSI Software Target 3.3 is the first  release that can be used in a production environment. The product 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," according to the product overview  at   Microsoft's  Download Center.
This type of storage architecture offers a number of  benefits, according to the product overview. It can be used to achieve high  availability with Microsoft's Hyper-V hypervisor using the "live  migration" feature. Storage for application servers can be consolidated,  including on a Windows failover cluster. Finally, Microsoft iSCSI Software  Target 3.3 supports the remote booting of diskless computers "from a  single operating system image using iSCSI."
Microsoft's team ran this release the software through  extensive testing, particularly with Windows Server failover clusters and  Hyper-V, according to the announcement. One scenario involved using Microsoft  iSCSI Software Target in a "two-node Failover Cluster," with 92  Hyper-V virtual machines storing data to one of the nodes. The team introduced  a failure in the main node and found that all 92 virtual machines switched to  the second node without a noticeable effect on the underlying application.
Microsoft is recommending using Service Pack 1 with Windows  Server 2008 R2 for this release of Microsoft iSCSI Software Target. The product  can be installed in a Hyper-V virtual machine. It doesn't work with a core  installation of Windows Server 2008 R2.
