- The Dot Hill 3000 Series Next-Generation Storage Platform Delivers High Performance, Scalability, Redundancy and Advanced Data Management, Making it the Ideal Solution for Fault Tolerant Computing

Dot Hill Systems Corp. (Nasdaq: HILL), a leading provider of Unified Virtual Storage and SAN storage solutions, today announced Stratus Technologies has selected the Dot Hill 3000 Series next-generation storage platform for their ftScalable storage line to address the continuous availability data management requirements for mission-critical applications in the financial services, healthcare, manufacturing, public safety, government, and travel & transportation sectors.

With distribution in North and South America, Europe, Middle East and Africa (EMEA), Japan and Asia Pacific, Stratus is a proven provider of uptime assurance for organizations with mission-critical applications that must always be protected against downtime and data loss, with solutions based on its fault tolerant ftServer line. Today, Stratus is a trusted solutions provider of uptime assurance in the industry, via its unique combination of resilient technologies, combined with proactive availability management services.

Since 2006, Stratus Technologies has leveraged Dot Hill AssuredSAN™ based storage platforms as the foundation for its ftScalable storage solution for all Intel processor-based ftServer lines supporting Windows, Linux, VMware, and Stratus’ own VOS operating system. The Dot Hill AssuredSAN product line features a number of key technology innovations that support performance, scalability and availability that make it ideal for fault-tolerant computing, where downtime is not an option.

Launched in February 2010, Dot Hill’s next-generation 3000 Series features support for higher performance 8Gb Fibre Channel storage area networks (SANs), dual interface 8Gb Fibre Channel and iSCSI, and enhanced data management capabilities. In addition, the new 3000 Series offers increased energy efficiency by supporting automatic drive spin-down technology which, in addition to Dot Hill’s patented battery-free alternative for cache memory protection, provides further energy cost savings for “green” end users. Availability features such as redundant, hot-swappable components, online firmware upgrades, and hot spares are augmented by optimized SAS drive topology handling and integration with the Stratus Active Service Network features unique to Stratus.

“Dot Hill and its products align perfectly with Stratus’ unrelenting commitment to deliver industry-leading uptime assurance to our customers,” said Roy Sanford, Stratus chief marketing officer. “We focus on system-wide reliability, and proactive availability management. Dot Hill has collaborated closely with us from the start of our relationship to ensure our storage products are fully integrated into that customer value proposition.”

“Stratus’ selection of our new Dot Hill 3000 Series next-generation storage platform underscores its value as a high-performance storage solution that can be relied on to support the continuous availability, mission-critical computing needs of businesses today,” said Garrett Wein, vice president of worldwide OEM sales, Dot Hill Systems. “The solution supports fast access to data via 8Gb Fibre Channel, plus redundancy via dual controllers, hot swappable drives, fans, and power supplies.”

Dot Hill storage solutions offered by Stratus scale to support up to 72 SAS or nearline SAS disk drives, totaling up to 72 terabytes (TB) of capacity based on today’s 1 TB disk drive capacities, and feature a 2U 24-drive rackmount footprint. Dot Hill’s AssuredSnap™ snapshot capability further enables companies to reduce the burden of meeting modern data retention policies and compliance requirements associated with government regulations such as the HIPAA and Sarbanes-Oxley acts. Dot Hill disk array storage solutions are NEBS (Network Equipment Building System) Level 3 compliant and designed to meet the rigorous MIL-STD-810F requirements of the U.S. Department of Defense for land, sea and air deployment.
