Micr osoft iSCSI Softwar e T arget
The Microsoft iSCSI Software Target snap-in is a standard feature of Windows Unified Data Storage
Server 2003. This snap-in makes it possible not only for the storage server to connect to remote iSCSI
targets, but also to serve as an iSCSI target. With Microsoft iSCSI Software Target, you c an create and
manage iSCSI targets, crea te and manage disks for storage, and implement backup and recovery
support using snapshots.
Virtual disk storage
The disks you create using iSCSI Software Target are iSCSI virtual disks, which are files in the virtual
hard disk (VHD) format. These virtual disks offer flexible and effective storage. They are dynamically
extendable to provide extra capacity on demand, enable efficient storage utilization, and minimize the
time requi
redtocreatenewdisksandthedowntimetypicallyrequiredtoinstallnewdisks.
Snapshots
To facilitate backup and recovery operations, you can schedule and create snapshots of iSCSI virtual
disks. A snapshot is a point-in-time, read-only copy of an iSCSI virtual disk. Snapshots are typically used
as interim copies of data that has been modified since the most recent backup. Snapshots offer the
following advantages:
• Snapshots can be scheduled to be created automatically.
• Snapshots are space-efficient because they are differential copies.
• It is not necessary to close files or stop programs when creating snapshots, so application servers
can continue ser vicing clients without disruption.
• Each snapshot is typically created in less than one m inute—regardless of the amount of data.
• Snapshots are useful for fast system recovery of files and volumes, in case of accidental data
deletion by a user, overwritten data, or data corruption resulting from a malicious program.
• Snapshots can be mounted loca lly o r exported to facilitate backup and recovery operations.
