Abstract: A computer-implemented method for sharing of non-critical resources of autonomous vehicles. The method identifies available non-critical resources of autonomous vehicles by a communicative connection. The method receives a request from a computing device of a requesting user for travel in an autonomous vehicle and for use of the available non-critical resources, wherein the request is received. The method determines the autonomous vehicles having the non-critical resources available to fulfill the request and presents to the requesting user information regarding the available resources. The method receives a selection of a set of the available non-critical resources and generates a resource stack configuration from the selected set of available non-critical resources, and the method grants access to the generated resource stack configuration.

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 method for verification of content of tape cartridges in a tape library system using tape drives of the tape library, is provided. The method includes instructing the tape drive to perform tape cartridge verification on the tape cartridge. The method further includes after completion of the tape cartridge verification, unloading the tape cartridge to its original storage position. The method further includes transmitting verification data of the tape cartridge verification to a database of the tape library system for analysis.

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: An object-based data storage system includes a memory and a processor for executing machine executable instructions configured for implementing logical containers for data objects each having a global identifier. The containers are configured for storing metadata including a first parameterization value descriptive of a number of storage nodes and a second parameterization value descriptive of a classification of the data objects. The machine executable instructions are further configured for implementing a first object storage ring for addressing storage locations across the multiple storage nodes using a surjective function.

Abstract: For data backup and recovery based on linked file repositories with each of the linked file repositories representing an individual file system capable of storing at least one version of a file and being connected to at least one server system, each of the linked file repositories are placed in a certain position for storing a certain version of the file. Each position of each of the linked file repositories is continuously numbered. A number of the versions of the file are determined by the position of the one of the linked file repositories.

Abstract: A tape drive system server includes a non-volatile memory used as a cache memory for storing data files, at least part of the cache memory comprising a first region managed using a First In First Out policy management and a second region managed using a Least Recently Used policy management; a file system interface for interacting with data files stored on a tape drive system; an interface for allowing one or more remote systems reading and writing data stored on the cache memory; the server configured to: receive from the one or more remote systems one or more write requests for writing one or more data files; interpret attributes associated to data files instructed to be written by the one or more remote systems; and store data files instructed to be written by the remote systems according to the interpreted attributes.
