In addition, Dell came out separately with its first direct-attached, external RAID SAS array, the PowerVault MD3000, designed to compete directly against SANs. PowerVault MD3000 is aimed at clustered applications, such as Microsoft SQL Server 2005 and Microsoft Exchange Server 2007. These applications themselves include more advanced replication capability, and the MD3000 is designed to complement this by providing easy-to-use and highly capable storage at a lower price than a full SAN, according to the company.The throughput performance aids applications such as video services and file serving, while the high I/O operations per second aim the product at applications with high transactional performance requirements, such as databases and e-mail applications. Key features of the PowerVault MD3000, according to the company:
In addition, the PowerVault MD3000 uses dual active/active RAID controllers to enhance performance and availability, producing up to 1.4G bps of throughput and approximately 90,000 I/O operations per second.
- Capacity: up to 4.5TB per system
- Expansion: ability to expand with up to two MD1000 arrays for a total of 13.5 TB
- Two-node clustering: This is the first PowerVault MD product to support two-node clustering providing high availability and fault tolerance for applications or services
- Multihost capability: Attach up to four Dell PowerEdge servers
