摘要： 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. Execution of the instructions causes the processor to: instantiate the first object storage ring, receive the global identifier and the metadata by the first object storage ring, and generate a storage address by the first object storage ring for the data object using the global identifier, the first parameterization value and the second parameterization value as input to the surjective function.

摘要： 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.

摘要： An approach for managing a data package is provided. Network throughput is determined to exceed a threshold. A sender computer determines a hash digest of the data package by using a hash function selected based on central processing unit utilization. If the hash digest is in a sender hash table, then without sending the data package, the sender computer sends the hash digest and an index referring to the hash digest so that a recipient computer can use the index to locate a matching hash digest and the data package in a recipient hash table. If the hash digest is not in the sender hash table, then the sender computer adds the data package and the hash digest to the sender hash table and sends the data package and the hash digest to the second computer to check the integrity of the data package based on the hash digest.

摘要： A system and method for reading files stored on a storage system is disclosed. The method includes communicatively coupling one or more remote systems for reading files stored in storage with a first set of files according to a predetermined data format and in a cache memory with a second set of files, the second set of files being a subset of the first set of files. Next one or more remote systems are received at least one read request for reading a sequence of files. A determination is made, among the files of the sequence of files, whether one or more cached files are already stored in the cache memory and whether one or more remaining files are not already stored in the cache memory. Creating, within the one or more remaining files, an order according to which the remaining files should be read on the storage system.
