Using the metrics reported by this model, administrators can find quick and accurate answers for the following performance queries:

  • Are all storage arrays on the RAID storage device adequately sized? Is any array running out of space?
  • Do any error-prone drive channels exist on the device? If so, which one is it, and what type of errors are experienced by it?
  • Has any drive channel failed?
  • Are there I/O-intensive logical drives?
  • Is any logical drive guilty of ineffective cache usage? If so, which one is it?
  • Has any logical drive failed?
  • Is I/O and transaction load balanced across all controllers on the device? Is any controller I/O-intensive?
  • Are all controllers available?
  • Has any battery failed or is about to reach its end of life?
  • Are any fan canisters, SFP transceivers, temperature sensors, power supply units, and fans experiencing failures?
  • Is any drive port or host port down?
