Patent ID: 11436138

Abstract:
Techniques are provided for automated adaptive endurance tuning of solid-state storage media. For example, a storage control system tracks usage metrics associated with utilization of solid-state storage devices of a storage system, wherein the storage system comprises an amount of over-provisioned capacity allocated in the solid-state storage devices according to an over-provisioning factor. The storage control system determines a current endurance value of the data storage system based at least in part on the usage metrics, and compares the current endurance value to a target endurance value to determine if the current endurance value differs from the target endurance value. The storage control system automatically adjusts the over-provisioning factor in response to determining a difference between the current endurance value and the target endurance value, and automatically adjusts the amount of over-provisioned capacity allocated in the solid-state storage devices according to the adjusted over-provisioning factor.
