Abstract: A method includes receiving a plurality of files where each file represents an object. The method further combines selected files of the plurality of files into an aggregation file and stores the aggregation file on low-latency storage media, such as disk storage media. The method represents the aggregation file with a single inode that is stored on the low-latency storage media. The method migrates the aggregate file to high-latency storage media, such as tape storage media, while leaving the single inode representing the aggregation file on the low-latency storage media. By collecting files into larger aggregation files, the number of files archived is significantly reduced and the files archived are of larger size. The reduced number of files and increased size of the files improves archival and retrieval performance due to reduced metadata operation overhead. A corresponding system and computer program product are also disclosed.

Abstract: A computer-implemented method according to one embodiment includes receiving a request to perform a high-latency media (HLM) action on an object or a group of objects, identifying metadata associated with the object or group of objects, and conditionally allowing the HLM action to be performed on the object or group of objects, based on the HLM action and the metadata associated with the object.

Abstract: Embodiments for predetermining optimal demount position for demounting data storage cartridges in an automated data storage library by a processor. A selected demount position may be predetermined, while performing one of a plurality of robotic movements by an accessor, for each mounted data storage cartridge for demounting data storage cartridges in the automated data storage library. The selected demount position is recalculated for each mounted data storage cartridge for demounting the data storage cartridges while performing a subsequent demount operation, where the selected demount position is determined according to the recalculation prior to a demount command being issued. Accordingly, the idle time of the accessor during a demount operation may be reduced.

Abstract: In one embodiment, a method includes determining a size of a file associated with each job in a job queue of files to be migrated to one of a plurality of drives that includes at least one of each of the following: a faster drive and a relatively slower drive. The availability of a faster drive is determined. The file associated with the job in the job queue having a file size larger than a threshold is sent to the faster drive.

A selected demount position may be predetermined, while performing one of a plurality of robotic movements by an accessor, for each mounted data storage cartridge for demounting data storage cartridges in the automated data storage library such that each predetermined selected demount position is stored in a lookup table of predetermined selected demount positions for a subsequent demount operation. The idle time of the accessor during a demount operation may be reduced.
