Predictive workload placement amongst storage systems

An apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

• generating, for each of a plurality of storage arrays, a projected system activity level for the storage arrays, wherein the projected system activity level for the storage array is generated based on a performance profile of a workload combined with a rate at which each of a plurality of monitored performance metrics associated with the storage arrays are changing over time;
• identifying, based on the projected system activity levels including the performance profile of the workload and the rate at which each of the plurality of monitored performance metrics associated with the storage arrays are changing over time, an optimal storage array for receiving the workload;
• and
• placing the workload on the optimal storage array.

A computer program product disposed upon a non-transient computer readable medium, the computer program product comprising computer program instructions that, when executed, cause a computer to carry out the steps of:

• generating, for each of a plurality of storage arrays, a projected system activity level for the storage arrays, wherein the projected system activity level for the storage array is generated based on a performance profile of a workload combined with a rate at which each of a plurality of monitored performance metrics associated with the storage arrays are changing over time;
