Pivot3 protects data using RAID 5 when only one or two Databanks are deployed, but its distributed RAID software automatically creates a Databank cluster across three or more Databanks so it can withstand the failure of a single Databank. As more Databanks are added, the Pivot3 distributed RAID software automatically redistributes and load-balances data across the multiple Databanks.
Other firms are also looking to meet the specific storage needs of video surveillance. For example, Intransa's StorStac storage system supports iSCSI-based video surveillance, but gives companies the flexibility to increase performance or capacity on a more granular level. Firms may add Intransa's Performance Controller Units (PCUs) when they require more performance or higher levels of failover, or the company's Storage Capacity Enclosures (SCEs) when more storage resources are needed.
Webster sees digitized video surveillance as almost certain to grow as it eliminates tape management and the out-of-space conditions that CCTV and DVRs can introduce. By placing it all in one digitized storage pool that's easily accessible, says Webster, "if you have a five-minute sequence of corporate video surveillance data that you need to locate, you now have all of that data at your fingertips."
