A modular data storage tape library includes a modular frame having a form factor similar to other types of computing racks. The modular data storage tape library includes a hermetically sealed enclosure within the modular frame and a cooling portion within the modular frame. Data storage tapes, data storage drives and robotics for moving the data storage tapes are included within the hermetically sealed enclosure. A heat exchanger transfers heat from the hermetically sealed enclosure to the cooling portion outside of the sealed enclosure through a boundary of the hermetically sealed enclosure without introducing air from the data center into the hermetically sealed enclosure. Because air is neither introduced nor removed from the hermetically sealed enclosure, humidity fluctuations are minimal, if existent, and contaminants are prevented from entering the hermetically sealed enclosure, thus increasing the life spans of the data storage tapes included in the hermetically sealed enclosure.

A computer program product for acclimating at least one electronic data storage library component for insertion or removal from an electronic data storage library, the computer program product comprising: one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media. The program instructions include program instructions to insert at least one data storage library component into an acclimation device; to monitor at least one environmental condition within the acclimation device; to determine if the at least one environmental condition within the acclimation device meets a predetermined threshold; to adjust the at least one environmental condition within the acclimation device; and to remove the at least one electronic data storage library component from the acclimation device in response to determining that the at least one environmental condition within the acclimation device meets the predetermined threshold.

The technology disclosed herein enables automatic implementation of a physical barrier to protect access to data on removable storage media. In a particular embodiment, a method provides determining that the item moved into a storage position using an automatic transfer mechanism and determining that a condition for protecting the item is satisfied. Upon determining that the condition is satisfied, the method provides implementing a physical barrier that prevents the automatic transfer mechanism from removing the item from the storage position.

An information processing device performs control to record, out of a plurality of pieces of data to be recorded on a plurality of magnetic tapes, a data group in which a value corresponding to a size of a data group for which a storage period is within a predetermined range is equal to or more than a threshold value and a data group in which the value is less than the threshold value, on magnetic tapes different from each other.

An information processing device performs, in a case where, out of a plurality of magnetic tapes on which data is multiplexed and recorded, the number of the magnetic tapes which is equal to or more than a predetermined number of multiplexes are stored in a storage unit, first control to handle each magnetic tape stored in the storage unit, to be readable and writable, and performs, in a case where the number of the magnetic tapes which is less than the number of multiplexes are stored in the storage unit, second control to handle the magnetic tape stored in the storage unit, to be read-only.

A tape may be mounted into a tape drive. Mounting the tape into the tape drive may include loading the tape from a storage slot. The tape drive may request a first record of the tape from a tape storage subsystem. The tape drive may determine whether the first record of the tape exists in the tape storage subsystem. The tape drive may load the first record of the tape in random access memory (RAM) of the tape drive. The first record may include one or more data entries. The tape drive may append a new data entry to the first record. The first record may be transitioned to a second record upon being appended with the new data entry. The tape may be unmounted from the tape drive.

A cartridge management system that manages a plurality of cartridges, in each of which a magnetic tape is housed, includes a processor, and a memory incorporated in or connected to the processor, in which the processor is configured to execute data rewrite-in processing of rewriting data stored in the magnetic tape, in a specific cartridge among the plurality of cartridges based on an access frequency indicating a frequency of access to the data, and cartridge replacement processing of replacing the data stored in the magnetic tape of the specific cartridge and the data stored in the magnetic tape of another cartridge among the plurality of cartridges.
