  • Reduced-Resource Block Thin Provisioning
    Publication number: 20100082715
    Abstract: A computer-executed method reduces a storage array's physical spindle requirements, leading to reduced power and resource costs, as compared to block thin provisioning. A computer-executed method for managing access of a plurality of applications to a storage array comprises monitoring storage space usage in a file system, and modifying size of logical units by selective increases and decreases based on the storage usage.

  • Storage replication system with data tracking
    Publication number: 20060182050
    Abstract: A storage replication method comprises replicating data from a source among a plurality of destinations and tracking data modifications in the destinations. Identification of the modifications is mutually communicated among multiple destination arrays. In a source failover event, a selected destination is established as a new source, reforming the replicated data in the remaining destinations into synchrony with the new source.
