Patent ID: 11507327

Abstract:
Techniques for estimating performance metrics of standalone or clustered storage systems. The techniques include receiving a request from a storage client for an estimated capacity or capability of a storage system to handle a specified workload pattern within a specified periodicity interval, in which the estimated capacity or capability of the storage system is represented by a headroom metric. The techniques further include, in response to the request from the storage client, obtaining a value of the headroom metric for the specified periodicity interval using a performance model characterized by at least a peak load reserve (PLR) metric and a long-term load reserve (LLR) metric, in which the obtained value of the headroom metric corresponds to the minimum of respective values of at least the PLR metric and the LLR metric. The techniques further include upgrading, scaling-up, and/or scaling-out the storage system based on the value of the headroom metric.
