A disk array is a disk storage system which contains manifold disk drives. It is differentiated from a disk field, in that an array has cache memory and superior functionality, like RAID and virtualization.
Components of a characteristic disk array include:
* Disk array controllers
* Cache memories
* Disk enclosures
* Power supplies
Typically a disk array provides increased availability, resiliency and maintainability by using additional, redundant components (controllers, power supplies, fans, etc.), frequently up to the point at what time all single points of failure (SPOFs) are eliminated from the design. Additionally those mechanisms are often hot-swappable.
Typically, disk arrays are divided into five categories: NAS, Modular SAN arrays, Monolithic SAN arrays, Storage Virtualization and Utility SAN Arrays.
