Evaluating a set of storage devices and providing recommended activities

A computer program product having a non-transitory computer readable medium which stores a set of instructions to evaluate a set of storage devices, the set of storage devices including at least one disk drive and constructed and arranged to store data on behalf of one or more host computers, the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:

• receiving, by the computerized circuitry, storage device evaluation factors which (i) map individual possible storage device error events to individual weights and (ii) map cumulative weights to recommended activities;
• receiving, by the computerized circuitry, a storage device error log containing storage device error entries identifying actual individual storage device error events which were encountered by the set of storage devices while data storage operations were performed on the storage devices by a set of storage processors over a period of time, wherein the storage device evaluation factors map a first possible storage device error event to a first individual weight for a first type of storage device, and wherein the storage device evaluation factors map the first possible storage device error event to a second individual weight for a second type of storage device;
• analyzing, by the computerized circuitry, the storage device error entries based on the storage device evaluation factors by weighting each individual one of the actual individual storage device error entries based on the storage device evaluation factors to produce a set of evaluation results identifying a set of recommended activities to be performed on the set of storage devices, wherein the analyzing includes i) assigning the individual weights mapped by the storage device evaluation factors to the actual storage device error events, ii) tabulating the assigned individual weights to form aggregate weights for the storage devices, and iii) matching the aggregated weights for the storage devices to the cumulative weights mapped by the storage device evaluation factors to identify the set of recommended activities;
• and
• displaying the set of recommended activities to a user.

An electronic apparatus to evaluate a set of storage devices, the set of storage devices including at least one disk drive and configured and arranged to store data on behalf of one or more host computers, the electronic apparatus comprising:

• a user interface;
• memory;
• and
• processing circuitry coupled to the user interface and the memory, the processing circuitry being constructed and arranged to:
• receive, from the memory, storage device evaluation factors which (i) map individual possible storage device error events to individual weights and (ii) map cumulative weights to recommended activities,
• receive, from the memory, a storage device error log containing storage device error entries identifying actual individual storage device error events which were encountered by the set of storage devices while data storage operations were performed on the storage devices by a set of storage processors over a period of time, wherein the storage device evaluation factors map a first possible storage device error event to a first individual weight for a first type of storage device, and wherein the storage device evaluation factors map the first possible storage device error event to a second individual weight for a second type of storage device,
• analyze the storage device error entries based on the storage device evaluation factors by weighting each individual one of the error entries based on the storage device evaluation factors to produce a set of evaluation results identifying a set of recommended activities to be performed on the set of storage devices, wherein the storage device error entries are analyzed at least in part by i) assigning the individual weights mapped by the storage device evaluation factors to the actual storage device error events, ii) tabulating the assigned individual weights to form aggregate weights for the storage devices, and iii) matching the aggregated weights for the storage devices to the cumulative weights mapped by the storage device evaluation factors to identify the set of recommended activities, and
• display, through the user interface, the set of recommended activities to be performed on the set of storage devices.
