A disk array controller is a device that manages the physical disk drives and presents them to the computer as logical units. It often implements hardware RAID , thus it is sometimes referred to as RAID controller .
Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T. or SMART) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs). [3] Its primary function is to detect and report various indicators of drive reliability, or how long a drive can function while anticipating imminent hardware failures.
Encryption implementation in an internal array controller architecture. For an internal array controller configuration, the array controller is generally a PCI bus card situated inside the host computer. As shown in the diagram, the PCI array controller would contain an encryption unit where plaintext data is encrypted into ciphertext. This ...

As of 2020, it includes a RAID system capable of RAID levels 0, 1, 5, and 10, a block level SSD caching accelerator ("Smart Response Technology") with support for write-back and write-through modes for speed or data protection of any disk or RAID array, and support for intelligent caching, speedy recovery from certain issues, and for PCI ...
HP EVA4400 storage array, consisting of 2U controller enclosure (top) and 4 2U disk shelves. A disk array is a disk storage system which contains multiple disk drives. [1] It is differentiated from a disk enclosure, in that an array has cache memory and advanced functionality, like RAID, deduplication, encryption and virtualization.
The integrated controller presented the drive to the host computer as an array of 512-byte blocks with a relatively simple command interface. This relieved the mainboard and interface cards in the host computer of the chores of stepping the disk head arm, moving the head arm in and out, and so on, as had to be done with earlier ST-506 and ESDI ...
CTL-I (Controller Interface) [3] was an 8-bit word serial interface introduced by IBM for its mainframe hard disk drives beginning with the 3333 in 1972. [4] The 3333 was the first unit in a string of up to eight 3330 type hard disk drives; it contained a CTL-I controller and two 3330 type
