FULL ALLOCATION VOLUME TO DEDUPLICATION VOLUME MIGRATION IN A STORAGE SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17804109 titled 'FULL ALLOCATION VOLUME TO DEDUPLICATION VOLUME MIGRATION IN A STORAGE SYSTEM
Simplified Explanation
- The patent application describes a method, computer program product, and computer system for migrating data from a full allocation volume to a deduplication volume in a storage system. - The method involves moving the physical allocation of stored data from the full allocation volume to a virtual address range in a deduplication domain. - The deduplication metadata is set up to be a passthrough, meaning it allows the data to pass through without being processed. - Once the virtual address range is populated with the physical allocations, a background deduplication process is performed. - The deduplication process involves using a drive query hash interface to perform hash calculations on the physical drives where the data is stored. - The purpose of the deduplication process is to identify and eliminate duplicate data, reducing storage space requirements. - The innovation lies in the efficient migration of data from a full allocation volume to a deduplication volume, and the use of a passthrough metadata setup and background deduplication process. - This method and system can be implemented in a computer program product and computer system to improve storage efficiency and reduce storage costs.
Original Abstract Submitted
A method, computer program product, and computer system for full allocation volume to deduplication volume migration in a storage system. The method includes moving a physical allocation of stored data associated with a full allocation volume into a virtual address range in a deduplication domain and setting up the deduplication metadata to be a passthrough. The method then performs a background deduplication process on the virtual address range once populated with the physical allocations using a drive query hash interface to perform hash calculations on physical drives at which the data is stored.
