Multi-Tiered Storage Pool Provisioning via Auto-Tiering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current storage systems lack user-friendly solutions for managing multi-tiered storage pool provisioning, requiring users to manually configure complex parameters, which can be cumbersome, especially for novice users, and do not efficiently utilize different types of disks based on performance characteristics.
Innovation Solution
A method for managing multi-tiered storage pool provisioning that uses a storage management interface to identify optimal drive selections and configure RAID types and ratios, facilitated by an XML configuration file, allowing for auto-tiering and application-aware configuration recommendations, and providing a GUI interface for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration of storage pool parameters is required, then storage system functionality is achieved, but user operation complexity increases and ease of operation deteriorates
Solution Approach 1:
The system performs self-service by automatically selecting optimal drives and configuring storage pools based on predefined best practices and performance characteristics of available disks, eliminating the need for manual user configuration
Solution Approach 2:
The system automatically determines configuration parameters such as RAID type, drive selection, and pool size based on the performance characteristics of available disks and predefined best practices, changing parameters dynamically without user intervention
2Extent of automation
If automatic drive selection and configuration is implemented, then ease of operation improves, but extent of automation increases requiring more sophisticated system intelligence
Solution Approach 1:
The system incorporates predefined best practices and performance characteristics of different disk types established in advance, allowing automatic configuration decisions to be made based on pre-analyzed performance data without requiring complex real-time decision logic
Solution Approach 2:
The system uses an intermediary layer of predefined best practices and performance characteristics that mediates between available hardware resources and configuration decisions, simplifying the automation logic by relying on pre-established guidelines rather than complex algorithms
3Productivity
If multi-tiered storage pools are provisioned manually, then storage efficiency can be optimized, but time required for provisioning increases
Solution Approach 1:
The system automatically provisions multi-tiered storage pools by selecting appropriate drives and configuring parameters based on performance requirements, eliminating manual provisioning time while maintaining optimization
Solution Approach 2:
The system uses pre-established best practices and performance characteristics to make rapid provisioning decisions, avoiding the time-consuming manual analysis and configuration process while still achieving optimized storage allocation
Data Source
AI summary
A method is used in managing multi-tiered storage pool provisioning. One or more physical devices of a data storage system are configured for use in connection with provisioning a storage pool. A provisioning specification is received describing a RAID type and an auto-tiering selection. A rule is received describing one or more sets of data storage system best practices. Each of the one or more sets specifies data storage system best practices for a different type of data storage system including a first type associated with the data storage system. Configuration processing is performed in connection with initialization of the data storage system to configure a first portion of the one or more physical devices for use with auto-tiering in the storage pool. A rules engine and best practices for the first type of data storage system specified in the rule are used in performing the configuration processing.
