  • Failure data collection system apparatus and method
    Patent number: 8812443
    Abstract: An apparatus for collecting dump data collection receives an on demand data (ODD) dump request, pauses one or more scan loops, transfers dump data to an ODD dump buffer space, unpauses the scan loops, and offloads dump data from the ODD dump buffer space to the storage device. The apparatus may also prioritize dump data for transfer to the ODD dump buffer space, load balance dump data for transfer to the ODD dump buffer space, and schedule offloading of the dump data from the ODD dump buffer space to non-volatile storage.

  • Intelligent extent initialization in storage environment
    Patent number: 8595458
    Abstract: A method, apparatus, and computer program product for initializing a plurality of extents in a computing storage environment is provided. A plurality of states for each of the plurality of extents is defined to include either an initialized state or a modified state. The plurality of extents is initialized at an advance time, designating the plurality of extents as having the initialized state. Upon a first occurrence of a destage operation of a first extent of the plurality of extents, the first extent is designated as having the modified state.
