  • Patent number: 10417197
    Abstract: A computer-implemented method according to one embodiment includes identifying an accessing of a file within an operating system, checking an in-memory cache for path information associated with the file, checking an external cache for the path information associated with the file, conditionally retrieving the path information associated with the file by performing a file system lookup and adding the path information associated with the file to the in-memory cache and the external cache, returning the path information, and reorganizing the external cache to put file information that is frequently accessed together in a single block or adjacent blocks.

  • Publication number: 20190235758
    Abstract: Autonomic compression including balancing performance of a compression technique and storage space savings in data storage based on an access characteristic is provided. The access characteristic of file data is determined including a read access and/or a write access. A space management action is dynamically selected to be applied to the file data. The selection automatically balances between a storage size and an access performance of the file data based on the access characteristic. The selected space management action is applied on the file data including changing a state of compression of the data.

  • Patent number: 10311026
    Abstract: The embodiments described herein relate to managing compressed data to optimize file compression for efficient random access to the data. A first partition of a first data block of a compression group is compressed. The first compressed partition is stored in a first compression entity. An in-memory table is maintained, which includes updating the in-memory table with data associated with an address of the stored compressed first partition. At such time as it is determined that the first compression entity is full, the in-memory table is compressed and written to the first compression entity. Accordingly, the in-memory table, which stores partition compression data, is store with the compression entity.

  • Patent number: 10235374
    Abstract: A key-value store for storing and retrieving user files based on key-value pairs, hereafter referred to as KVPs. For each user of the key-value store, each file of a set of files of said each user is stored as one or more pairs of KVPs. Each of said one or more pairs comprises a KVP of a first type and a KVP of a second type. The KVP of the first type comprises at least a part of contents of said each file, whereas the KVP of the second type comprises metadata (and possibly attributes) of said each file. Each KVP of the second type links to one or more KVPs of the first type. Further provided are related method and computer program products.

  • Publication number: 20190034119
    Abstract: A method for scheduling data services in a heterogeneous storage environment is disclosed. In one embodiment, such a method includes instrumenting, in a heterogeneous storage environment, each of a plurality of storage systems to generate events when operations are performed thereon. The events are detected and indexed in a single namespace. These events may then be analyzed to generate a statistical model of I/O activity occurring in the heterogeneous storage environment over a period of time. From the statistical model, the method determines periods of reduced I/O workload across the heterogeneous storage environment. The method then schedules data services to occur during these periods of reduced I/O workload. A corresponding system and computer program product are also disclosed.

  • Publication number: 20180373745
    Abstract: In one embodiment, a method includes receiving, at a centralized index operating in a cloud environment via a messaging bus, first events spawned by a first processor managing an object store accessible via the cloud environment. The method also includes receiving, at the centralized index, second events spawned by a second processor managing an archival store accessible via the cloud environment. Also, the method includes normalizing metadata in the first and second events. Moreover, the method includes indexing and storing the metadata in the centralized index. The object store and the archival store operate in different object subsystems of the cloud environment. Other systems, methods, and computer program products are described for managing import, export, and copy of data within a public tiered object storage environment in accordance with more embodiments.

    Abstract: Embodiments relate to policy-based, multi-scheme data reduction for a computer memory. An aspect includes receiving a plurality of policy rules by a policy engine of the computer memory, wherein a first policy rule specifies applying a first data reduction scheme to data in the computer memory based on the data matching first characteristics, wherein a second policy rule specifies applying a second data reduction scheme to data in the computer memory based on the data matching second characteristics, wherein the first data reduction scheme is different from the second data reduction scheme. Another aspect includes determining, by the policy engine, that first data in the computer memory matches the first characteristics, and that second data in the computer memory matches the second characteristics. Yet another aspect includes applying the first data reduction scheme to the first data, and applying the second data reduction scheme to the second data.

  • Publication number: 20180307705
    Abstract: In an approach to maintain data integrity in a computer data storage system, a clone management table is generated for a clone file tree that includes a relationship between at least one parent file and a clone file. The parent file is restored by: (i) determining that the parent-child relationship exists between the parent file and the clone file based on an entry in the clone management table, (ii) restoring data blocks in the parent file to the file system based on an analysis of an entry in the clone management table for the parent file and an identification of data blocks included in the clone file, and (iii) generating a new instance of the parent file based on the data blocks included in the file system and the entry in the clone management table for the clone file tree.
