Product Details

PowerVault™ MD1220 direct-attached storage array is the second generation of Dells energy-efficient, small form factor (SFF), 2.5-inch drive expansion enclosure. The PowerVault MD1220 offers seamless expansion for Dell™ PowerEdge™ servers with PERC H800 Host-RAID adapter, providing IOPs needed to satisfy performance-intensive application. This expansion array can support 24, 2.5-inch SAS hard-disk drives (HDDs) or solid-state drives (SSDs) in a 2U array and expands up to 8 arrays per adapter. 

The PowerVault MD1220 leverages SAS 2.0 technology, which enables double the throughput over previous generation, with a 6Gb/s SAS interface and offers performance optimization with automatic I/O load balancing across redundant paths and enhanced security, over previous generation with new self-encrypting drive (SED) support. 

The PowerVault MD1220 improves energy efficiency over previous generation with 80PLUS® Silver Certified power supplies. This enhancement augments the efficiencies already gained with 2.5-inch drives and variable speed fans.

The PowerVault MD1220 is a Energy-efficient storage-expansion array that provides the performance to satisfy demanding single- server applications.


6Gb/S SAS: With up to 35-percent increase in IOPs and twice the throughput of last-generation arrays, the PowerVault MD1220 can satisfy even the most performance-intensive applications, such as Web hosting, database and e-mail.

Solid State Drives: Pair the increased IOPs and throughput of 6Gb/s SAS with support for solid state drives (SSD), which have 3x the IOPs performance over 15K SAS drives and offer an ideal solution for applications that rely on random block access.

Automatic I/O Load Balancing: Further optimizing the performance of the PowerVault MD1220, the PERC H800 Host-RAID adapter has automatic I/O balancing between the server and storage array. The PERC H800 can detect when a single path starts to get saturated and then balance the I/O traffic across both paths.

The PowerVault MD1220 direct-attached storage array can deliver the speed, performance and reliability to satisfy performance intensive single server applications that store active and frequently changing information.
