Patent ID: 7873505

Claim:
An apparatus for predicting scheduled downtime for a system, the apparatus comprising: a processor; a scheduled system downtime analyzer configured for determining a plurality of scheduled system downtime estimates comprising first and second scheduled system downtime estimates for the system; wherein the first and second scheduled system downtime estimates are determined using at least one scheduled system downtime event model and downtime metrics; wherein the first and second scheduled system downtime estimates each comprise at least one of a hardware downtime estimate determined using a hardware model, a firmware downtime estimate determined using a firmware model, and a software downtime estimate determined using a software model; wherein at least one of the scheduled system downtime event models used for determining at least one of the first and second scheduled system downtime estimates is configured for determining a scheduled system downtime estimate using pro-rating based at least in part on a percentage of system capacity expected to be affected by an associated event for which the scheduled system downtime estimate is determined; and a system downtime aggregator configured for aggregating the scheduled system downtime estimates to produce thereby scheduled system downtime results for the system, and for updating at least one scheduled system downtime event model using at least a portion of the scheduled system downtime results.
