Three New Patents for Dot Hill

Total now at 75

Dot Hill Systems Corp. announced the addition of three new patents to the company’s technology portfolio, upping the company’s intellectual property total to 75 patents granted by the United States Patent and Trademark Office.

Adding to its patented, environmentally conscious EcoStor battery-free cache technology, an integral part of Dot Hill’s AssuredSAN storage, U.S. patent 7,809,886 is the company’s fifth super-capacitor related innovation. The new patent makes it possible to transfer write-data to non-volatile memory if power loss occurs and ensure data is secured.

Dot Hill EcoStor represents a move to green storage by eliminating the need for cache backup batteries, helping to save the environment and reducing service costs for end users. The EcoStor battery-free cache design provides a permanent backup of unwritten cache data in the event of a power failure unlike traditional battery-based designs, which typically hold data for only up to 72 hours, assuming a fully charged battery.

In its ongoing commitment to making storage easier to manage and more accessible, Dot Hill has been awarded U.S. patent 7,818,436 for its invention that improves manageability and ease-of-use by providing a method for multiple users to manage a storage system over multiple networks. Each user can customize their user experience, ‘filtering’ messages, which may consist of information on new volumes, configurations, drive status or firmware updates. By eliminating unnecessary messages and only sending changed information, the patent allows administrators to focus on other priorities. In addition, this technology records and remembers active user sessions, eliminating the need for storage administrators to log in multiple times.

U.S. patent 7,793,145 makes it easier for storage administrators to manage host connection cabling by providing a method for a storage controller to automatically determine if host-side cabling is properly arranged between host computers and redundant storage controllers. The invention takes into account the absence or presence of switches between host computers and storage controllers, as well as single- or dual-port host bus adapters in the host computers, and provides automatic updates to ensure cabling is properly arranged.

"Dot Hill innovation is helping to solve many of today’s most challenging storage problems – helping IT to improve performance, increase availability, simplify operations and reduce costs," said Jim Kuenzel, senior vice president of engineering at Dot Hill Systems. "Built on the innovation of our steadily expanding patent portfolio, the Dot Hill Assured family of storage solutions delivers outstanding performance, efficiency, flexibility and scale."

Dot Hill was recently recognized as one of the top five companies in its peer group for its significant amount of intellectual property by MDB Capital at its Bright Lights Conference. The Bright Lights Conference highlights the IP stories of 50 public companies which rank in the 90th percentile for technology leadership from over 1,600 small cap companies with U.S. patents granted, as determined by PatentVest, MDB’s proprietary IP business intelligence database. Dot Hill’s intellectual property, demonstrated by its extensive patent portfolio, is embodied in the company’s pillars of innovation within its Assured architecture – providing a complete platform for addressing customers’ storage needs.
