  • OPTIMIZED FLASH BASED CACHE MEMORY
    Publication number: 20120297127
    Abstract: Embodiments of the invention relate to throttling accesses to a flash memory device. The flash memory device is part of a storage system that includes the flash memory device and a second memory device. The throttling is performed by logic that is external to the flash memory device and includes calculating a throttling factor responsive to an estimated remaining lifespan of the flash memory device. It is determined whether the throttling factor exceeds a threshold. Data is written to the flash memory device in response to determining that the throttling factor does not exceed the threshold. Data is written to the second memory device in response to determining that the throttling factor exceeds the threshold.

  • SYNCHRONIZATION FOR INITIALIZATION OF A REMOTE MIRROR STORAGE FACILITY
    Publication number: 20120239622
    Abstract: A method includes computing, in a local storage system having a local volume with a plurality of local regions, respective local signatures over the local regions, and computing, in a remote storage system having a remote volume with remote regions in a one-to-one correspondence with the local regions, respective remote signatures over the remote regions. A given remote region is identified, the given remote region having a given remote signature and a corresponding local region with a given local signature that does not match the given remote signature. The data in the given remote region is then replaced with data from the corresponding local region.
