A method of predicting usage levels of solid-state drives (SSDS) includes receiving time series usage data from each SSD over a plurality of monitoring intervals (lags), and using a first portion of the time series usage data to train (fit) an ARIMA model to the time series data. A unique ARIMA model (order) is determined for each SSD from the unique time series % usage data of each SSD. The ARMIA model is then fit to the time series % usage data and used in a predictive manner to predict a future date when the % usage will exceed a threshold % usage value. By predicting when the SSDs will meet particular thresholds, it is possible to plan for and procure replacement SSDs to enable currently installed SSDs to be removed from service before the currently installed SSD % usage levels exceed threshold values, thus enabling the currently installed SSDs to be repurposed.

Data automation and predictive modeling for planning and procuring solid state drive replacements

Aspects of the present disclosure relate to detecting and correcting a storage array's drive sectors to prevent data loss. In embodiments, a storage array's telemetry information is monitored. Further, one or more state or operational metrics of the storage array's storage drives are measured. Additionally, each storage drive is scrubbed based on each drive's relative scrubbing priority defined by the telemetry information and each storage drive's state or operation metrics.

An amount of storage space required to maintain counter information for a storage system is reduced without reducing a temporal granularity or tracking granularity of the counter information. Rather than periodically recording actual (i.e., raw) counter values for counters, difference (i.e., delta) values may be recorded. For a given counter, a difference (delta value) between a value of the counter for a given point in time (PIT) and a value of the counter for a previous PIT may be determined, and this delta value may be stored as opposed to storing the raw counter value. This delta value may be a significantly smaller value than the raw value. To further reduce the amount of storage space required, no value may be stored for a counter for a given PIT if it is determined that there is no difference between a counter value for the given PIT and a previous PIT.

Space-efficient storage of system-monitoring data

An aspect of the present disclosure relates to one or more techniques to identify and resolve storage array errors. In embodiments, an error notification related to a computing device can be received. One or more threads related to the error notification can further be identified. Additionally, an error resolution technique can be performed based on each identified thread.
