    Abstract: A storage system includes a plurality of solid-state storage devices and a storage controller operatively coupled to the plurality of solid-state storage devices, the storage controller including a processing device, the processing device to receive, from a first solid-state storage device of the plurality of solid-state storage devices, an indication that data stored at the first solid-state storage device is affected by read disturb. In response to receiving the indication, the processing device is further to identify a second solid-state storage device of the plurality of solid-state storage devices for the relocation of the data and transmit, to the first solid-state storage device, a command comprising information associated with the relocation of the data from the first solid-state storage device to the second solid-state storage device, wherein the command causes the first solid-state storage device to relocate the data to the second solid-state storage device.

    Abstract: A method of using boot-time metadata in a storage system is provided. The method includes writing a fragmentation stride to a solid-state storage device of the storage system, the fragmentation stride defining a granularity on which fragmentation of erase blocks of the solid-state storage device occurs. The method includes allocating portions of erase blocks for at least one process in the storage system, in accordance with the fragmentation stride and writing boot up metadata at offsets that are based on the fragmentation stride, in the solid-state storage device.

    Abstract: A method of automatic load rebalancing includes determining that a new storage device was added to a storage array comprising a plurality of storage devices, wherein the new storage device is distinct from the plurality of storage devices. The method further includes, in response to the determining, identifying a first shard on a first storage device of the plurality of storage devices, wherein the first storage device has a fullness metric that is equal to or exceeds a fullness threshold. The method further includes moving, by a processing device of a storage array controller of the storage array, the first shard from the first storage device to the new storage device.

    Abstract: A processor-based method for secret sharing in a computing system is provided. The method includes encrypting shares of a new secret, using a previous secret and distributing unencrypted shares of the new secret and the encrypted shares of the new secret, to members of the computing system. The method includes decrypting at least a subset of the encrypted shares of the new secret, using the previous secret and regenerating the new secret from at least a subset of a combination of the unencrypted shares of the new secret and the decrypted shares of the new secret.

    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.

    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.
