ABSTRACT:
A data storage system in which each of a set of disks has a first portion for either popular data or error correction information (parity or Reed-Solomon code symbols) associated with the popular data, and a second portion used for other data. A disk controller connected to the set of disks maintains a first popular data block in the first portion of a first of the set of disks and a second popular data block in the first portion of a second of the set of disks. The system maintains at least two of the disks in an active state. The active disks are selected to insure that any data in the popular data blocks can be determined from data stored in the active disks. An additional disk is maintained in an active state if write access is permitted or if there is an additional popular data block.
