摘要: A mirrored memory for a data processing system. The system includes two device controllers and related disk drives storing the data. Each of is divided into logical volumes. controller contains plurality reading processes correspondence table that establishes process to be used in retrieving from corresponding drive. responds read command identifies volume by using select appropriate transferring physical storage containing designated volume.
