Quantum QXS hybrid storage includes the storage management tools expected today.
Thin provisioning streamlines the tasks of provisioning and modifying volumes, allowing IT managers to respond to data growth as needed. Disk space is only used when written to and LUN size is independent of physical disk space used. IT managers can add storage when needed, easily expanding volumes non-disruptively.
With Storage Pooling, the disks—whether physical or logical—can be aggregated into pools from which the logical volumes are allocated. This greatly simplifies storage allocation by eliminating the need to manage partitioned space on the physical storage resources.
Within each collection of disk drives that make up a storage pool, data is further protected with RAID redundancy within each tier. In a typical RAID system, rebuilding a drive can be time consuming, especially with high capacity drives, because each sector requires rebuilding. Quick delivers an accelerated rebuild operation as only the sectors that contain actual data are rebuilt, resulting in up to 5 times faster restoration of the RAID set. For instance, a drive that is only 50 percent utilized will rebuild in 50 percent less time with Quick.
