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: A system and method for maintaining the safety of volume operations. A storage controller receives a request to delete a first volume. In response to this request, the storage controller can delete a link between the first volume and its anchor medium. The storage controller can also delay the deletion of the first volume's anchor medium. Later on, if the user wishes to restore the first volume, the storage controller can reconnect the first volume to its previous anchor medium, effectively restoring the first volume to its former state and undoing the deletion operation.

Abstract: A system and method for performing search optimization operations. In order to optimize lookups for received data requests, a storage controller attempts to collapse the medium graph, thus reducing the number of mediums in which the storage controller must look to find a given block. One technique for collapsing the medium graph involves promoting individual mappings from a lower-level medium to a higher-level medium. Another technique for collapsing the medium graph involves pushing medium range pointers higher up in the medium mapping table to reduce the number of mediums that must be searched.

Abstract: A system and method for exposing volumes with underlying read-write mediums to user operations. When a medium is in the process of being migrated to a storage array, a volume which relies on the medium can be exposed to user operations (e.g., snapshots, read and write operations) once the portions of the medium which underlie the volume have been migrated. The volume can be exposed to user operations while one or more other portions of the medium are unfilled and while the medium is in an intermediate read-write state.

Abstract: Accesses of blocks of multiple zoned storage devices are monitored to detect one or more characteristics of the accesses of the blocks. A preventative action is performed in response to the detecting, wherein the preventative action includes sending an indication from the storage system upon determining that one or more of the accesses of the blocks are indicative of a malicious action based on the one or more characteristics.

Abstract: A method of storage system operation, and related computer-readable media and storage system are disclosed. One or more processors or storage system controllers monitor accesses of blocks of storage memory of the storage system. The monitoring is to detect one or more characteristics of the accesses of the blocks. From the characteristic(s), it is determined the one or more accesses of the blocks are indicative of a malicious action. In response to such determining, the storage system performs a reaction action.

Abstract: A system and method for performing copy offload operations. When a copy offload operation from a first volume (pointing to a first medium) to a second volume (pointing to a second medium) is requested, the copy offload operation is performed without accessing the data being copied. A third medium is created, and the first medium is recorded as the underlying medium of the third medium. The first volume is re-pointed to the third medium. Also, a fourth medium is created, the second volume is re-pointed to the fourth medium, and the second medium is recorded as the underlying medium of the targeted range of the fourth medium. All other ranges of the fourth medium have the second medium as their underlying medium.
