Optical disc library device capable of dynamically scheduling optical drives and its dynamic scheduling method

Abstract

The invention provides an optical disk library device capable of dynamically scheduling optical drives and a dynamic scheduling method thereof, belonging to the field of optical disk storage. The optical disk library device includes: a plurality of cabinets, which are arranged in sequence along the horizontal direction to form a cabinet group, and each cabinet stores multiple optical discs, and each cabinet is equipped with a manipulator; multiple guide rail components, all spanning along the horizontal direction of the cabinet group In the cabinet group; a plurality of optical drive assemblies, each optical drive assembly includes a plurality of optical drives, and the optical drive assembly forms a slidable connection with the guide rail assembly; and a control unit, which is connected to each manipulator and each optical drive assembly for controlling the specified The optical drive assembly is moved to the designated cabinet, and the manipulator is controlled to load the designated optical disc into the designated optical drive of the designated optical drive assembly, and unload the designated optical disc to the designated cabinet after the read and write operations are completed. The optical disk library device and the dynamic scheduling method thereof of the present invention can save the cost of the device while ensuring the data migration efficiency, and can also reduce the single point failure rate of the whole device.

Description

technical field [0001] The invention relates to the field of optical disk storage, in particular to an optical disk library device capable of dynamically scheduling optical drives and a dynamic scheduling method thereof. Background technique [0002] Large-scale cold data storage centers usually deploy a lot of optical disc libraries in the form of standard cabinets. The optical disc library is composed of optical disc magazines, manipulators and optical drive groups. The disc magazine compartment accommodates a plurality of disc magazines, and each disc magazine accommodates a plurality of optical discs. The manipulator is used to carry the optical discs, usually loading the optical discs in the optical disc magazine into the optical drive, or unloading the optical discs in the optical disc drive into the optical disc magazine. There are usually multiple optical drives in the optical drive group, and the optical drives can work in parallel to meet the overall data read and...

AI Technical Summary

Problems solved by technology

Optical drives are expensive components and a concentrated point of failure in optical libraries

That is to say, in the prior art, the optical disc data migration efficiency and device cost are a pair of contradictory factors that restrict each other.
