iStorage Server Ultimate

iStorage Server is an IP SAN solution that allows you quickly export existing storages such as disk images, physical disks, partitions, CD/DVD-ROMs, tapes or any other type of SCSI based devices and even a variety of popular CD/DVD images to its client machines, which delivers immediate benefits allowing storage to be consolidated, virtualized and centrally managed. iStorage Server also provides RAID-1 (mirror) feature, which allows you create two devices for mirror backup, the mirror devices can be local image files or remote iSCSI devices. iStorage Server has been added support for Microsoft Virtual Disk File (VHD) and VHD snapshots at the recent release.
