Effective resynchronization in virtual storage area network using dynamic partitioning and data deduplication techniques

Abstract:

Techniques for redistributing a virtual storage area network (vSAN) data component in a distributed-computing system are provided. In one embodiment, a method includes storing a data component in a plurality of storage nodes associated with the cluster of storage nodes. The method further includes identifying, within the data component, one or more subcomponents to be redistributed and identifying a set of target storage nodes. The method further includes obtaining one or more data structures representing the one or more subcomponents to be redistributed; and determining, among the set of target storage nodes, one or more destination storage nodes. The method further includes redistributing, in accordance with data storage policy, the one or more subcomponents from one or more source storage nodes to the one or more destination storage nodes.
