METHOD, COMPUTER SYSTEM AND STORAGE SYSTEM FOR CONTROLLING MATERIALIZATION IN A STORAGE MEDIUM BASED ON OBJECT ID AND STORAGE SYSTEM

摘要

PURPOSE: A method, a computer system, and a storage system for controlling materialization in a storage medium based on an object identification are provided to accurately and efficiently implement the materialization by directly transferring materialization order control requests to a storage device. CONSTITUTION: A host system (1510) provides writing commands for writing data on a storage medium (1550) and an object identification (ID) allocated to the writing commands to the storage medium. Using the object ID allocated to the writing commands, a storage device determines materialization order or atomicity between the writing commands and processes the writing commands based on the determined result. The host system allocates same object ID to the writing commands belonging to a group. [Reference numerals] (1510) Host interface; (1530) Controller; (1550) Storage medium
