Abstract:
1. A method correcting a storage load imbalance in a storage network environment with virtual clusters, each having one or more virtual machines, the method comprising: generating an input/output (I/O) ranking for each of the virtual machines based on I/O traffic between the virtual machines and storage devices associated with the virtual machines; generating a storage utilization ranking for each of the storage devices based on I/O requests that are unavailable at an array cache, wherein the requests are from the virtual machines to associated storage devices; identifying a first virtual machine on a first virtual cluster with an I/O ranking, which is higher than an I/O threshold, associated with a first storage device having a first storage utilization ranking which is higher than a threshold; identifying a second virtual cluster associated with a second storage device having a second storage utilization ranking which is lower than the threshold; and moving the first virtual machine from the first virtual cluster to the second virtual cluster.
