Conflict management for application directed data placement in storage environments

摘要

A storage controller receives hints provided by one or more applications over a period of time, wherein the hints are used by the storage controller for organizing data in storage managed by the storage controller. Data on conflicts caused by the provided hints are collected over the period of time. Based on the collected data on the conflicts, one or more conflict avoidance rules are executed to reduce possibility of future conflicts.

1. A method, comprising:
receiving, by a storage controller, hints provided by one or more applications over a period of time, wherein the hints are used by the storage controller for organizing data in storage managed by the storage controller; collecting data on conflicts caused by the provided hints over the period of time; and based on the collected data on the conflicts, executing one or more conflict avoidance rules to reduce possibility of future conflicts, wherein the method further comprises: reorganizing data, in response to determining that the conflicts exceed a first threshold, and a number of conflicting applications exceeds a second threshold; reducing lease window of data if all the conflicting applications have same priority; and providing higher priority to an application with highest rejection rate.
