iStorage Server Ultimate

iStorage Server is an enterprise-grade iSCSI SAN and IP SAN solution that quickly transforms existing storage resources — including disk images, physical disks, partitions, CD/DVD-ROMs, tape devices, and other SCSI-based devices — into centrally managed network storage.
The software supports high availability (HA) clustering and replication for building fault-tolerant storage systems, as well as Windows RDMA technologies including iSER and RDMA-based replication for high-performance storage networking.
iStorage Server also includes virtual tape device support for enterprise backup software integration, making it an ideal iSCSI SAN solution for virtualization, backup, and data center storage environments.
