Abstract
A reading algorithm for a set of mirrored disks sends groups of reads to one disk, then sends the next group to the other disk. This provides a more optimal use of disks for sequential reads than previous algorithms. An enhanced version uses snooping of the read requests and switches disks immediately for the read if the requests are not sequential, or within a given number of records of sequential. Additionally, the size of the requests can change the number of requests grouped together in the enhanced version.
