- Supports performance-intensive applications such as Web server, database and e-mail
- 2.5-inch small-form-factor (SFF) array, energy-efficient storage expansion enclosure
PowerVault™ MD1220 direct-attached, energy efficient storage array that provides the performance to satisfy demanding applications.
Expansion for Performance-Intensive Single-Server Applications
PowerVault™ MD1220 direct-attached storage array is the second generation of Dell's 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, so you don’t have to trade capacity for performance.
Optimizing performance, enhancing security while doubling the throughput: 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 (input/output) load balancing across redundant paths and enhanced security, over previous generation with new self-encrypting drive (SED) support.
Improved efficiency: The PowerVault MD1220 improves energy efficiency over previous generation, with new 80PLUS(R) Silver Certified power supplies. This enhancement augments the efficiencies already gained with 2.5-inch drives and variable speed fans.
Satisfying Even the Most Performance-Hungry Applications
The PowerVault MD1220 direct-attached storage array storage array offers compelling performance,
- 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.
Your Energy-Conscious Storage
The PowerVault MD1220 is a small-form-factor (SFF) array that helps manage power, heat and space consumption in your data center. In fact, 2.5-inch disks consume up to 50% less power and 70% less space than 3.5" drives.
Additionally, the MD1220 power supplies are 80PLUS® Silver Certified, and, with variable-speed, temperature-controlled fans, are designed to deliver optimal performance and energy efficiency
Keeping Your Data Safe
Access and accuracy of your data are key to the success of any business. The PowerVault MD1220 has been engineered to help maximize your uptime and the security of your data.
Redundant Path with I/O Load Balancing: You can rest assured that your data will be available when you need it. Even if a single cable path fails from one port of the PERC H800, you will continue to have access to your data through the second port.
Self-Encrypting Drives (SED): Self-encrypting drives help to ensure that your data is secure with drive-level encryption, so, even if a drive is removed from its storage system or the server it in which it is housed, the data on the drive is encrypted and rendered useless to anyone who attempts to access it without the appropriate security authorization. Additionally, SED supports instant secure erase of drives, which permanently removes data when repurposing or decommissioning drives.
Hot-Swappable Drives: With hot-swappable drives, you can remove and replace drives even when your system is operating. No need to shut down, and no need to reboot: New drives are available right away.
Leveraging the PERC H800 RAID Controller
The PowerVault MD1220 leverages the PERC H800 Host-RAID adapter with the latest PCI Express 2.0 interface, offering excellent performance for enterprise.
The configuration of the PERC H800 Host-RAID adapter helps to increase reliability and fault tolerance by enabling the software to recognize the entire array as a single unit, regardless of how many disks are activated for storage in the array. With the PERC H800, customers can choose the RAID option that supports their application. The PERC H800 supports RAID levels 0, 1, 5, 6, 10, 50 and 60.
Dell PowerVault MD1220 storage array is engineered to work optimally with Dell PowerEdge servers. Dell OpenManageTM Storage Manager Software can manage both the external array and internal storage within the server itself. The PowerVault MD1220 is supported behind the following servers: R210,T310,T410,R410,R510,R610,T610,R710,T710,R910,R810. See PERC H800 server compatability matrix for a list of currently supported servers.
Streamlining storage management through a single, common interface helps reduce resource load on the system, and is easier to navigate for the user as well. The PowerVault MD1220 utilizing the same 2.5-inch drives as 11th Generation PowerEdge servers, and the same power supplies and fans as the PowerVault MD1200, helping to reduce the number of spares required.
