Write-based data management using endurance tiers in a storage system

Abstract:

A method, system, and computer program product manages a storage system. Writes to sections in solid state storage devices in endurance tiers in the storage system are monitored by a computer system over a period of time. Responsive to a write rate for the writes to a section in the sections in an current endurance tier in the endurance tiers exceeding a maximum recommended write rate for the current endurance tier during the period of time, data is moved from the section in the current endurance tier to a higher endurance tier in the endurance tiers having a higher maximum recommended write rate than the maximum recommended write rate for the current endurance tier.
