Abstract

Embodiments of the present invention include array-cluster systems, and methods employed in array-cluster systems, that allow snapshot data to be distributed over multiple arrays within an array cluster. By distributing snapshot data over multiple arrays within an array cluster, the load, generally related to the number of access operations directed to the arrays within an array cluster, may be more evenly distributed among the arrays of an array cluster, preventing increased latencies associated with overloading individual arrays Distributed snapshots may also facilitate high availability and fault tolerance within an array cluster.
