Abstract: A system, apparatus, and product for allowing access to a partially replicated dataset, including: detecting, by a target storage system, that a dataset will be replicated from a source storage system to the target storage system; exposing, by the target storage system, the dataset for user operations prior to receiving the entire dataset; receiving, by the target storage system, a request to read a portion of the dataset that has not been received by the target storage system; and retrieving, by the target storage system, the portion of the dataset.

Abstract: A method may include detecting, by a computing device based on a problem signature, that a system has experienced a problem that is associated with the problem signature, wherein the problem signature comprises a specification of a pattern of events indicative of the particular problem experienced by at least one other system; determining that the particular problem violates an operational policy of the system; and deploying one or more corrective measures that modify the system to resolve the problem.

Abstract: Restoring a storage system from a replication target, including: receiving, by a first storage system from a computing device, data to be stored on the first storage system; reducing, by the first storage system, the data using one or more data reduction techniques; sending, from the first storage system to the second storage system, the reduced data, wherein the reduced data is encrypted; and retrieving, by the first storage system from the second storage system, the reduced data, wherein the reduced data is encrypted.

Abstract: Supporting multiple replication schemes across distinct network layers, including: replicating, over a first type of network messaging layer, data between a first storage system and a second storage system; selecting a different messaging layer for data replication; and replicating, over a second type of network messaging layer, data between the first storage system and the second storage system.

Abstract: Prioritizing garbage collection based on the extent to which data is deduplicated, including: determining, for one or more data elements, a number of deduplicated references to each data element; storing, for each of the data elements, the data element in an area of the storage device that contains other data elements with a similar number of deduplicated references; and adjusting a garbage collection schedule for the storage device, wherein garbage collection operations are performed more frequently on areas of the storage device that contain data elements with a relatively low number of deduplicated references.

Abstract: A system and method for performing replication using mediums. A snapshot ‘S’ is selected for replication, and the anchor medium ‘M’ of S is identified. The replica storage array ‘R’ to which M is being replicated determines a list of medium extents which are available. R sends this list to an original storage array ‘O’ and O generates a list of medium extents which need to be sent to R. Only those medium extents corresponding to M which R does not already have will be sent from O to R. Also, R can obtain medium extents from other source storage arrays during the replication process.
