  • Patent number: 10089183
    Abstract: A method and apparatus is disclosed herein for checking the consistency of deduplication metadata after an unclean shutdown of a deduplication computing system. The method may include mounting a deduplication file system of a deduplication computing system after an unclean shutdown of the deduplication computing system. Furthermore, the method may include initiating a reconstruction and consistency check of deduplication metadata associated with the deduplication file system. Furthermore, the method may include receiving a user operation prior to completion of the reconstruction and consistency check of the deduplication metadata, and processing the user operation in parallel with the reconstruction and consistency check of the deduplication metadata.

  • Patent number: 10353872
    Abstract: A method and apparatus is disclosed herein for converting a virtual machine from an initial hypervisor format to a target hypervisor format utilizing deduplication metadata. The method may include generating a copy of a virtual machine by replication of deduplication metadata for one or more files corresponding to the virtual machine. Furthermore, the method may include opening the copy of the virtual machine from the replicated deduplication metadata. The method may also include converting the replicated deduplication metadata from an initial hypervisor format to a target hypervisor format to generate a converted virtual machine.

  • Patent number: 10599356
    Abstract: A method and apparatus for utilizing virtual machines to pool memory from disparate server systems that may have disparate types of memory is described. The method may include establishing communication between a pool virtual machine and two or more publisher virtual machines. The method may also include aggregating, by the pool virtual machine, portions of memory from each of two or more publisher servers to generate a pool of memory, and providing an application with access to the pool of memory, through the pool virtual machine.

  • Patent number: 10255287
    Abstract: A method and apparatus is disclosed herein for maintaining deduplication metadata on disk separate from an in-memory deduplication file system for a deduplication computing system. The method may include reading deduplication metadata from a first memory of a deduplication computing system. Furthermore, the method may include maintaining deduplicated data for a file system in a second memory, and maintaining the deduplication metadata that describes the deduplicated data of the file system in the first memory of the deduplication computing system, wherein the first memory is a different type of memory and separated from the second memory in the deduplication computing system. Furthermore, the method may include accessing the deduplication metadata in the second memory in response to receipt of a request by the deduplication computing system to perform a first operation with deduplicated data of the file system in the second memory.

  • Patent number: 10089320
    Abstract: A method and apparatus is disclosed herein for maintaining data consistency in persistent memory in an in-place-update file system of a deduplication computing system. The method may include receiving a data write request to write a block of data from a volatile memory to a non-volatile memory in an in-place-update file system of deduplication computing system. Furthermore, the method may include determining whether the data write request is to perform an in-place update of an existing block in the non-volatile memory, and converting a type of write operation associated with the request from a requested write operation type to a new data allocation write operation when the data write request modifies the existing block. Furthermore, the method may include processing the new data allocation write operation to write the block of data from the volatile memory to the non-volatile memory using an ordered sequence of file system data journaling and writes to the non-volatile memory.
