Features

Storage with Room to Grow

• More and more organizations are using data-intense tools, suffering from slow or small e-mail boxes, and adding ever-increasing numbers of drives to handle their storage needs. The Dell PowerVault MD1120 can help. It offers exceptional capacity and performance while using 2.5” drives that consume less power and take up less space than 3.5” drives.The MD1120 is Dell’s first enclosure to offer small form factor (SFF) 2.5” Serial Attached SCSI (SAS) disk drives. When connected to Dell’s PowerEdge™ RAID Controller (PERC), the MD1120 can scale up to six enclosures, housing up to 144 drives.

High-End Performance

• Hard drive performance is essential for your data-hungry, I/O-intensive applications. The PowerVault MD1120 offers drives connected to a fast, three gigabit-per-second SAS interface. This is the perfect combination for high-end applications such as e-mail, databases, and online transaction processing.

Maximum Efficiency

• The SFF drives also help manage power, heat, and space usage in your data center, consuming up to 50% less power and 70% less space than 3.5” drives. Additionally, the PowerVault MD1120 uses high-efficiency power supplies and variable speed, while temperature controlled fans to help minimize power consumption.
