Abstract
A system for mirroring source data to two or more mirrors includes first and second processors designated to communicate with first and second remote mirrors, respectively. First and second queues in the system receive requests to mirror source data at first and second mirrors, respectively. Each of the queues is periodically scanned by a processor corresponding to the mirror associated with that queue. A mask provides information indicative of any pending mirror requests for sending the source data to the first and second mirrors.
