The AssuredSAN 3004 models improve on previous-generation 3000 Series arrays by providing next-generation affordable storage to meet entry-level requirements with greater capacity and performance. In addition, 3000 Series customers can take advantage of easy field upgradability to the next-generation AssuredSAN 3004 RAID controller, simplifying deployment to achieve an instant performance and connectivity boost.

Leveraging improved price/performance for the Band 21 storage market, AssuredSAN 3004 models provide a full range of flexible, high-speed host connectivity options, and Dot Hill's proven 99.999 percent data availability, making them an excellent fit for vertical market customers as well as standard data center applications such as email, backup, replication and virtualized server environments. In addition, both the AssuredSAN 3004 and 4004 models now provide 50 percent higher capacity storage in the same rack space with support for 6 terabyte hard disk drives.

Dot Hill AssuredSAN 3004 storage systems feature a wide range of high-bandwidth host interface options including 16Gb and 8Gb Fibre Channel, and 10Gb and 1Gb iSCSI with Dot Hill's unique, flexible Fibre Channel/iSCSI converged interface. With the ability to support up to 288 terabytes of total capacity, Dot Hill AssuredSAN 3004 storage systems are available in a variety of 2.5-inch and 3.5-inch hard disk drives (HDDs).

"Dot Hill's ability to deliver more performance from its new 3004 entry-level system is right in line with what users are demanding," noted Mark Peters, senior analyst at Enterprise Strategy Group. "Performance needs are driven up by such things as consolidation, virtualization and VDI as well as many ever-more-demanding applications, all of which are endemic across IT organizations of all sizes. And users realize that affordable performance is paramount; when respondents in ESG's survey of Storage Market Trends were asked about the key messages that storage vendors should emphasize, performance and cost were ranked as the top two value propositions."

AssuredSAN 3004 Solutions Deliver Highest Available Bandwidth with Amazing Flexibility

AssuredSAN 3004 converged interface solutions provide the flexibility to run 16Gb Fibre Channel, 8Gb Fibre Channel, 4Gb Fibre Channel, 10Gb iSCSI and 1Gb iSCSI networks using the same hardware. With a quick swap of a transceiver module, IT administrators can configure their storage in the field to 16Gb Fibre Channel or 10Gb iSCSI.

AssuredSAN 3004 converged interface arrays are fully backward-compatible with 8Gb/4Gb Fibre Channel and1Gb iSCSI networking solutions such as switches and host bus adapters. All AssuredSAN 3004 models are meta-data compatible with previous-generation AssuredSAN arrays, so customers can accomplish data-in-place migration by simply upgrading controllers.

"AssuredSAN 3004 storage systems offer a highly compelling combination of performance and capacity at a tremendous value," said Jason Beeson, solutions director at Hammer plc, the number one European distributor dedicated solely to storage. "The flexibility of the converged interface models makes it easy and inexpensive for IT administrators to upgrade or change storage interfaces in the field from 8Gb to 16Gb Fibre Channel or convert to iSCSI. The AssuredSAN 3004 is ideal for any number of use cases, and is a perfect backup storage target solution for off-site replication."

Performance, Data Availability and Compatibility that Dot Hill Customers Expect

Dot Hill AssuredSAN 3004 solutions are built on the company's proven RAID architecture, and deliver up to 80 percent greater performance over previous-generation 3000 Series products, with sustained sequential read performance of up to 3300 MB/second and writes of up to 2400 MB/second and 40,000 input/output operations per second (IOPS) from disk. The Dot Hill RAID Companion Processor (RCP) allows AssuredSAN 3004 solutions to deliver dramatic performance gains at very aggressive price points, including streaming performance optimization to handle randomized, sequential workloads. Dot Hill's latest firmware utilizes a proprietary Adaptive Read-Ahead Algorithm that analyzes workloads and fine-tunes options for optimal performance, delivering better response times to meet IT service level agreements.

"Utilizing Dot Hill's proven, versatile controller architecture that is featured in all of our next-generation products, the AssuredSAN 3004 lineup is priced to maximize performance and terabytes per dollar, raising the bar for performance in an entry-level storage array," said Joe Swanson, vice president, marketing and business development, Dot Hill.
