Abstract:
1. A computer implemented method for selecting at least one preferred node for a specific functional role in a cluster, the method comprising the steps of: measuring, for each one of a plurality of nodes, at least one dynamic parameter, wherein the at least one dynamic parameter comprises at least connectivity to shared storage in the cluster, wherein connectivity is measured by determining how many of a total number of disks in the shared storage of the cluster are visible to each of the plurality of nodes; gleaning, for each one of the plurality of nodes, a user preference value quantifying a preference of each corresponding node for the specific functional role in the cluster, relative to the other nodes of the plurality; and calculating a preference rating for each one of the plurality of nodes, based on at least the at least one measured dynamic parameter and the gleaned user preference value for the corresponding node, wherein the preference rating for each specific node indicates its suitability for the specific functional role in the cluster, relative to the other nodes of the plurality.
