Qnap Assigned Patent
Automated tiering
By Francis Pelletier | August 19, 2019 at 2:20 pmQnap Systems, Inc., New Taipei, Taiwan, has been assigned a patent (10,365,831) developed by Yang, Teng-Feng, and Huang, Chung-Chih, New Taipei, Taiwan, for “automated tiering system and automated tiering method.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An automated tiering system and an automated tiering method are provided. The system includes a controller and multiple storage apparatuses that are layered into at least two tiers according to performance. In the method, an algorithm analyzer corresponding to each of multiple system configurations is executed to analyze data blocks in each storage apparatus to determine a target block of each data block after relocation and generate an estimated data allocation map. Then, a simulation engine is executed to classify the target blocks in the data allocation map according to a usage frequency of each target block so as to generate an exploitation map, and evaluate all of the exploitation maps to find the system configuration that raises the most performance as a best configuration. Finally, a data migrator is executed to migrate the data blocks in the storage apparatus according to the best configuration.”
The patent application was filed on November 28, 2017 (15/823,617).
