Keeping up with space constraints and the rising costs of energy are two of the greatest challenges facing IT departments today. By controlling power consumption and related heat output at the system level, however, organizations can deploy their hardware resources for optimum power and cooling efficiency to help control ongoing costs.The modular, rack-dense Dell? PowerVault? MD1120 direct attach storage (DAS) array is designed for efficiency and scalability?holding up to 24 low-power, 2.5-inch hard drives in a compact 2U enclosure for up to 12 TB of total storage capacity. A single dual-port Dell PowerEdge? Expandable RAID Controller (PERC) 6/E can connect to up to six PowerVault MD1120 enclosures, enabling use of up to 144 total drives and helping simplify management. And now, the PowerVault MD1120 can also support energy-efficient Seagate® Constellation? Serial Attached SCSI (SAS) hard drives.These industry-first 2.5-inch, 7,200 rpm, 500 GB drives are designed from the ground up specifically for enterprise-class nearline storage, providing the capacity, performance, and reliability to support high-density tiered storage applications. In Storage Performance Council (SPC) SPC-1C benchmark tests performed by Seagate engineers in January and February 2009, a 2U PowerVault MD1120 enclosure with 2.5-inch Constellation drives provided 93 percent higher performance than a 3U PowerVault MD1000 with 3.5-inch drives, or 2.9 times the performance per unit of rack space, while also consuming 40 percent less power. By deploying the Dell PowerVault MD1120 DAS array with Seagate Constellation hard drives, organizations can combine enterprise-class reliability, nearline performance, and scalability in a rack-dense, energy-efficient storage system.
