LONGMONT, Colo., June 16, 2015 (GLOBE NEWSWIRE) -- Dot Hill Systems Corp. (Nasdaq:HILL), a trusted supplier of innovative enterprise-class storage systems, today announced that it has been awarded a patent for its innovative method of protecting metadata. Only available in Dot Hill AssuredSAN hybrid arrays with the RealStor storage operating system, the latest innovation was developed to track virtualized data placement on every tier, ensuring the highest level of reliability and data integrity even beyond today's 99.999 percent availability.
Dot Hill's innovation, described in US patent number 8,990,542, provides three levels of protection for vital system metadata. Metadata contains location information for a storage system similar to a card catalog in a library. The innovation protects metadata by tracking serial numbers, cyclic redundancy checks (CRCs) and index numbers, which are embedded and distributed within the metadata record. The use of a space-efficient metadata storage area is superior to other schemes, which simply append metadata tracking information onto the metadata storage area.
"Building on our AssuredSAN product line's hallmark 99.999 percent data availability, Dot Hill continues to invent new ways to deliver superior data integrity that enhance our base software platform," said Ken Day, chief technology officer, Dot Hill. "This latest addition to our 100-plus patent portfolio provides IT customers with triple-level data checking and verification to protect against data corruption and loss. Organizations can depend on Dot Hill's unique RealStor storage operating system to safely deliver the data they need when they need it because real time matters."
Customers worldwide have implemented Dot Hill's RealStor storage operating system for simpler and more powerful data storage management, greater flexibility, exceptional performance and better data responsiveness. Dot Hill's RealTier tiered storage software provides SSD and HDD tiering in real-time by autonomically measuring data usage, identifying "hot" spots as they occur, and continuously moving data to the best tier, even as that data changes minute by minute. AssuredSAN 4004 storage systems with RealStor utilize flash to achieve up to 120,000 I/Os per second (IOPs). In addition to RealTier, RealStor fuels a powerful set of autonomic efficiencies including:
- RealCache™ - SSD caching
- RealThin™ - thin provisioning
- RealSnap™ - zero-impact snapshots
- RealQuick™ - rapid RAID rebuilds
- RealPool™ - autonomic storage resource pooling
The company's 103rd US patent joins an extensive list of Dot Hill innovations associated with the company's suite of data management services. Dot Hill's patent portfolio builds on the extensive intellectual property behind Dot Hill AssuredSAN solutions, which deliver rock-solid, wicked-fast solutions to customers and OEM partners.
