    Abstract: Preparing data for deduplication including: generating, by a storage system for a compressed data block, a padded compressed data block by padding the compressed data block to conform to a fixed block size, wherein the fixed block size is greater than a size of the compressed data block; storing, in the storage system, the padded compressed data block beginning at a block boundary of a storage device in the storage system; and performing block-based deduplication on the storage system, wherein the block-based deduplication determines whether the padded compressed data block matches one or more other padded compressed data blocks stored in the storage system.

    Abstract: Intelligent responses to errors in a storage system, including: after a first attempt to read data from a first set of resources in a storage system results in an error, determining whether to issue a second attempt to read data from the first set of resources in a storage system; responsive to determining not to issue the second attempt to read data from the first set of resources in a storage system, retrieving the data from a second set of resources in the storage system; and responsive to determining to issue the second attempt to read data from the first set of resources in a storage system, issuing a second read attempt to read the data, wherein the error correction effort level associated with the second attempt is increased relative to the error correction effort level associated with the first attempt.

    Abstract: Synchronizing snapshots between storage systems, including: receiving, from a source storage system, an identification of a snapshot to be replicated to a destination storage system, wherein the source storage system and the destination storage system are of different types; identifying, from hint information stored on the destination storage system, a most recent version of the snapshot that is stored on the destination storage system; issuing, to the source storage system, a request for an identification of the differences between the snapshot to be replicated to the destination storage system and the most recent version of the snapshot that is stored on the destination storage system; receiving, from the source storage system, the identification of the differences; and issuing a request to transfer, from the source storage system to the destination storage system, data associated with the differences.

    Abstract: A storage system switching between mediation models within a storage system, where the switching between mediation models includes: determining, among one or more of the plurality of storage systems, a change in availability of a mediator service, wherein one or more of the plurality of storage systems are configured to request mediation from the mediator service in response to a fault; and communicating, among the plurality of storage systems and responsive to determining the change in availability of the mediator service, a fault response model to be used as an alternate to the mediator service among one or more of the plurality of storage systems.
