Disk Array Controller Illustration.
I am deeply interested in the enterprise-level components of workstations and servers. Creating illustrations of components, such as Disk Array Cards, S-ATA backplanes, or other PCIe extensions, brings me joy. This is an illustration of a Disk Array Card, also known as a RAID card.
A disk array controller is a device that manages the physical disk drives and presents them to the computer as logical units. It almost always implements hardware RAID, thus it is sometimes referred to as RAID controller. It also often provides additional disk cache.
Disk array controller is often ambiguously shortened to disk controller which can also refer to the circuitry responsible for managing internal disk drive operations.
