Dot Hill Innovation Improves Storage Performance in SAS Environments

LONGMONT, Colo., Sept. 9, 2014 (GLOBE NEWSWIRE) -- Dot Hill Systems Corp. (Nasdaq:HILL), a trusted supplier of innovative enterprise-class storage systems, today announced a patented technology that improves storage performance in serial attached SCSI (SAS) environments.

Specifically, the invention described in Dot Hill's 98th US patent, numbered 8,812,913 provides a method to restore communications to a SAS link if a storage device malfunctions and causes configuration changes. Configuration changes initiate time-consuming device discovery processes, which delay normal I/O traffic. The Dot Hill innovation addresses this issue by segregating a misbehaving storage device into a special domain, preventing further configuration changes and normalizing I/O traffic among all interconnected SAS links.

Benefits of the Dot Hill innovation include:

  • Autonomous restoration of storage devices to operational status, with minimal need for user intervention or disruption to the overall system.
  • Ability to preserve proven configurations by isolating unproven or unqualified storage devices when they are added to a data storage system.
  • Ability to override the separation mechanism and integrate unqualified storage devices, such as may be required in an emergency or disaster situation.
  • Flexibility to dynamically manage any size pool of segregated storage devices. Storage devices may be added to or removed from the pool at any time, depending on testing status and override conditions.
  • Hierarchical management of drives in data storage systems.

"As we close in on our 100th patent, this latest innovation provides system administrators with more control and enhances Dot Hill's hallmark 99.999 percent data availability with enhanced system robustness," said Ken Day, chief technology officer, Dot Hill. "Dot Hill's vast portfolio of internally developed intellectual property allows us to deliver truly differentiated products to the marketplace that make a positive impact for our channel partners, IT professionals and the vertical markets that we serve."

Dot Hill's patent portfolio builds on the extensive intellectual property behind Dot Hill AssuredSAN and AssuredSAN Pro solutions, which deliver rock-solid, wicked-fast solutions to customers and OEM partners. Dot Hill's continuous innovation benefits the company's key vertical market customers in the Media & Entertainment, Telecommunications, Oil & Gas, Big Data & Analytics and Digital Imaging sectors, that require high-performing storage to support demanding applications.
