iSCSI Software Target is an optional Windows Server component that provides centralized, software-based and hardware-independent iSCSI disk subsystems in storage area networks (SANs).
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.
