Embodiment Construction

[0016] The contents of the preferred embodiments of the present invention will be disclosed in detail with reference to the contents described in the related drawings.

[0017] Many currently commercially available tiered storage mechanisms may be based on the following: 1) cost per byte of storage space; 2) data access patterns; 3) data migration and layout for infrequently accessed data to low-level storage devices; Sold storage tiering mechanisms address quality aspects related to the data users access on a day-to-day basis. In addition, these currently commercially available storage tiering mechanisms do not have configurable Quality of Service (QoS) parameters (Note: Quality of Service can also be abbreviated as (QoS)) that can be set for triggering tiering / migration based on application process and user data Data access latency threshold for a process.

[0018] Systems and methods described in exemplary embodiments of the present invention, such as those disclosed herei...

Abstract

The present invention relates to a system and method for QoS-based storage tiering and migration technique. The method allows for configurable application data latency thresholds to be set on a per user basis and / or a per application basis so that a storage tiering mechanism and / or a storage migrating mechanism may be triggered for moving application data to a different class of storage.

Description

technical field [0001] The invention relates to the field of storage resource and data management, in particular to a system and method of storage layering and migration technology based on quality of service (QoS). Background technique [0002] Currently available methods for providing storage resources and data management in data storage systems may not provide expected levels of performance. [0003] Therefore, there may be a need for a system / method capable of providing data resource and data management in a data storage system, the purpose of which system / method is to provide a currently available solution to the above-mentioned problems. Contents of the invention [0004] Correspondingly, an embodiment of the present invention relates to a storage system for providing quality of service (QoS) based storage tiering and migration, the method includes the steps: when an application process accesses the first storage layer of the storage system monitoring the applicatio...
