Line 1:
A '''disk array controller''' is a big device which manages the physical [[disk drives]] and presents them to the computer as [[Logical Unit Number|logical units]]. It almost always implements [[RAID#Hardware-based|hardware]] [[RAID]], thus it is sometimes referred to as '''RAID controller'''. It also often provides additional disk [[cache (computing)|cache]].
