Abstract:
A method for increasing the capacity of an array of N.sub.d storage units onto which video data is stored and which is operated so that the continuity of a plurality of video streams is maintained, said video data being striped across said array so that N.sub.d consecutive segments of S bits from a file are allocated one to each storage unit, said method comprisingadding N.sub.new storage units to said array of N.sub.d storage units to form a new array of N.sub.total =N.sub.d +N.sub.new storage units, andredeploying said data so that said data is striped across said new array of N.sub.total storage units so that N.sub.total consecutive segments from a file are allocated one to each of the N.sub.total storage units,wherein only said segments which are to be stored in said new storage units are moved.
