A disk array is an enterprise storage system which contains multiple disk drives. It is differentiated from a disk enclosure in that an array has cache and intelligence so that it can perform functions like RAID and virtualization.

Components of a typical disk array include

Typical disk arrays fall into five categories: NAS, Modular SAN arrays, Monolithic SAN arrays, Storage Virtualization and Utility SAN Arrays.

[edit] Network attached storage (NAS) arrays

Network attached storage is a hard disk storage system on a network with its own LAN IP address. Examples:

[edit] Modular storage area network (SAN) arrays

A SAN is a dedicated network separate from LANs and WANs, generally used to connect all the storage resources connected to various servers. Examples:

[edit] Monolithic (Enterprise)storage area network (SAN) arrays

Enterprise storage is the field of information technology focused on the storage, protection, and retrieval of data in large-scale environments. Examples:

[edit] Storage virtualization

Intelligent SAN or Storage Servers (Software that adds disk controller functionality to standard server hardware platforms). Hardware independent software that typically runs as a control program on top of a standard OS platform (Windows, Linux, etc.):
