2U DAS Storage Array
Dell PowerVault MD1220

The Dell PowerVault MD1220 direct-attached storage is the second generation of our energy efficient, small form factor (SFF), 2.5-inch drive expansion enclosure. The PowerVault MD1220 offers seamless expansion for PowerEdge servers and Dell Storage arrays while providing the Input/Output operations per second (IOPs) needed to satisfy performance-intensive applications.  The PowerVault MD1220 can deliver the speed, performance and reliability to satisfy data-hungry, performance-intensive, singleserver applications that store active and frequently changing information.

  • 6Gbps SAS: Twice the throughput of the previous generation of direct-attached storage, the PowerVault MD1220 can satisfy even the most performance-intensive applications such as web, database and email hosting
  • Solid-state drives (SSD): Pair the increased IOPs and throughput of 6Gbps SAS with support for SSDs for 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 H810 HostRAID adapter has automatic I/O load balancing to detect when a single path starts to get saturated and balances the I/O traffic across both paths
