RAID Cards
A RAID controller is a type of storage component that manages the disk drives in a RAID infrastructure. It provides the physical disk drives as logical units to the computer or server managing the RAID infrastructure.
A RAID controller is also known as a disk array controller.
A RAID controller typically provides grouped logical disk space to the operating system and other applications.
RAID controllers are classified based on:
- :: RAID level they support
- :: Number of internal or external ports
- :: Drive types (SAS/SATA/PATA)
- :: Number of drives it can support
- :: Front-end and back-end interfaces
- :: Native cache memory
The front-end interface of the RAID controller enables communication with the server host adapter, whereas the back-end interface communicates and manages the underlying disks.
