Problems solved by technology

For example, a user who previously enjoyed fast response times when accessing higher tier storage devices may not be able to accept the response times of lower tier devices
May even lead to greater dissatisfaction among users when they attempt to perform multiple concurrent data access operations from the same lower-tier storage medium or device resulting in longer access times

Embodiment Construction

[0043] The present invention provides a technical solution to the technical problems inherent in computerized data storage technology. In particular, the present invention improves the efficiency, consistency and predictability of file access in a tiered storage environment by considering user satisfaction with data access time.

[0044] This specification includes certain examples, and describes certain embodiments of the invention, in which storage devices or storage media are organized into tiers and in which storage devices or storage media are organized into tiers and , direct data to a specific layer for storage. However, these illustrations and exemplary embodiments should not be construed as limiting embodiments of the present invention to these factors.

[0045] In a tiered storage environment within the scope of the present invention, virtual or physical storage components can be ranked according to each component's read speed, write speed, average access time, stor...

Abstract

A cognitive hierarchical storage-management system receives feedback describing users' satisfaction with the way that prior data-access requests have been serviced. The system uses this feedback to associate each previously requested data element's metadata and storage tier with a level of user satisfaction. As feedback continues to be received, the system uses machine-learning methods to identifyhow closely specific metadata patterns correlate with certain levels of user satisfaction and with certain storage tiers. The system then uses these associations when determining whether it should migrate data associated with a particular metadata pattern to a different tier.

Description

Background technique [0001] The invention relates to the field of computerized storage management, in particular to improving the efficiency, consistency and predictability of file access in a hierarchical storage architecture. [0002] In such a tiered environment, virtual or physical storage components can be organized into tiers based on the performance characteristics of each component. Such tiering can be performed for a variety of reasons, for example, to reduce the need for more expensive high-speed storage devices, to better balance workloads, or to more efficiently align a class of storage devices with those stored in that class Match the criticality or access frequency of a type of data on the storage device. on such devices. [0003] In some cases, requests to access data that has been migrated from a higher storage tier to a lower storage tier may take significantly longer than before the migration. This degradation in storage performance can result in unaccepta...
