Abstract
Data Virtual Data Movers (VDM) are assigned to nodes of the storage cluster and a backup node is assigned for each data VDM. A system VDM on each node collects node statistics including operational parameters of the node and activity levels of the data VDMs on the node. A cluster manager collects the node statistics from each of the system VDMs and uses weighted collected node statistics to assign a node score to each node in the storage cluster. The cluster manager uses the node scores to identify possible data VDM movement combinations within the storage cluster by applying a set of hard rules and a set of soft rules to evaluate the possible data VDM movement combinations. If a VDM movement combination is selected, it is implemented by moving at least some of the data VDMs within the cluster to attempt to equalize node scores within the cluster.
