STORAGE SWITCH MIRRORED WRITE SEQUENCE COUNT MANAGEMENT

摘要

A storage switch (304) is disclosed that facilitates mirroring of data. For example, a target is mirrored when an identical (or almost identical) copy of the data is stored in two or more separate physical data stores (306). Because the various data stores may not be homogenous, they may provide for different burst sizes. To accommodate the different burst sizes, the switch provides different sequence counts for data packets sent to the different data stores that store the mirrored data.
