Dot Hill Wins Patents

U.S. patent 7,340,555, “RAID System for Performing Efficient Mirrored Posted-Write Operations” -- This patent pertains to Dot Hill’s SimulCache™ data caching architecture which leverages redundant RAID controllers, thus eliminating the performance degradation associated with conventional cache mirroring. The implementation of a high-speed dedicated PCI-Express bus streamlines write performance, resulting in superior overall system responsiveness to drive faster application throughput in database-related deployments.

U.S. patent 7,380,115, “Transferring Data using Direct Memory Access” -- This patent pertains to a method of improving controller performance by consolidating RAID functions into hardware and adding advanced memory controller technology.

U.S. patent 7,380,055, “Apparatus and Method in a Cached RAID Controller Utilizing a Solid State Backup Device for Improving Data Availability Time” -- This patent pertains to Dot Hill EcoStor™, an environmentally friendly "green," battery-free alternative that leverages a combination of super capacitors and compact flash technology for non-volatile cache memory. With up to a 10-year life span, EcoStor practically eliminates service calls for battery replacement, new battery inventory management, and the issues of battery disposal, as well as the periodic replacement downtime associated with batteries. Additionally, it offers an improved customer experience upon installation or power restore as it does not require lengthy battery charging time. The array operates in high-performance write-back cache mode within minutes of installation, versus hours with batteries.
