摘要： A method of encryption management with host-side data reduction includes identifying data to be written to a storage array and compressing the data to generate compressed data. The method further includes encrypting the compressed data to generate an encrypted data packet. The method further includes adding, by a processing device of a host, a padding bit pattern to the encrypted data packet to generate a data block for storage. The method further includes sending the data block to the storage array.

摘要： A method includes receiving, by a storage drive and from a storage controller, a modified first reservation command including a first logical unit identifier. The first reservation command includes a first host identifier to identify a first host controller was previously received by the storage controller from the first host controller. The first reservation command was modified by the storage controller to replace the first host identifier with the first logical unit identifier. The method also includes responsive to receiving the modified first reservation command, identifying, by the storage drive, a first logical unit of storage based on the first logical unit identifier of the modified reservation command. The method includes granting, by the storage drive, a reservation for access to the storage drive on behalf of the first host controller by associating the reservation for the first logical unit with a second logical unit of storage.

摘要： A method of distributed file deletion, performed by a storage system, is provided. The method includes receiving, at the storage system, a request to delete a directory and contents of the directory and adding the directory to a first set, listed in a memory in the storage system. The method includes operating on the first set, by examining each directory in the first set to identify subdirectories, adding each identified subdirectory to the first set as a directory, and adding each examined directory to a second set listed in the memory. The method includes deleting in a distributed manner across the storage system without concern for order, contents of directories, and the directories, listed in the second set.
