Abstract: A system and method for efficiently storing data in a storage system. A data storage subsystem includes multiple data storage locations on multiple storage devices in addition to at least one mapping table. A data storage controller determines whether data to store in the storage subsystem has one or more patterns of data intermingled with non-pattern data within an allocated block. Rather than store the one or more pattern on the storage devices, the controller stores information in a header on the storage devices. The information includes at least an offset for the first instance of a pattern, a pattern length, and an identification of the pattern. The data may be reconstructed for a corresponding read request from the information stored in the header.

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.

Abstract: Systems, methods, and computer readable storage mediums for generating an alert on a failure of a storage subsystem to phone home to the cloud in a replication environment. A dataset is replicated from a first storage subsystem to a second storage subsystem. The first and second storage subsystems also phone home log data to the cloud on a periodic basis. In response to detecting a failure of the first storage subsystem to phone home, the cloud generates and sends an alert to the second storage subsystem. In response to receiving this alert, the second storage subsystem starts disaster recovery operations for the dataset.

Abstract: Systems, methods, and computer readable storage mediums for replicating data to the cloud. A first dataset is replicated from a first storage subsystem to the cloud, with only the changes made to the first dataset since a previous replication event being replicated to the cloud. Additionally, the data may be deduplicated and compressed before being replicated from the first storage subsystem to the cloud. In some cases, the first dataset may be replicated to the cloud in a stream format which is not directly usable and then, at a later point in time, loaded onto a second storage subsystem from the cloud.
