Abstract: Sizing a virtual storage system, including: determining a change to one or more resource demands; determining, based on the change to the one or more resource demands, one or more modifications to one or more virtual components included as part of a virtual storage system architecture of a virtual storage system within a cloud computing environment; and initiating, responsive to the change to the one or more resource demands, the one or more modifications to the one or more virtual components included as part of the virtual storage system architecture of the virtual storage system, including replacing one or more of the virtual components with a higher performance virtual component.

Abstract: A method of data reduction in a partially encrypted volume includes receiving data to be stored on a storage array, decrypting the data using a first encryption key to generate first decrypted data, and decrypting the data using a second encryption key to generate second decrypted data. The method further includes comparing, by a storage array controller, a first compressibility value of the first decrypted data to a second compressibility value of the second decrypted data. The method further includes storing the first decrypted data if the first compressibility value is greater than or equal to the second compressibility value. The method further includes storing the second decrypted data if the second compressibility value is greater than the first compressibility value.

Abstract: Ensuring the appropriate utilization of system resources using weighted workload based, time-independent scheduling, including: receiving an I/O request associated with an entity; determining whether an amount of system resources required to service the I/O request is greater than an amount of available system resources in a storage system; responsive to determining that the amount of system resources required to service the I/O request is greater than the amount of available system resources in the storage system: queueing the I/O request in an entity-specific queue for the entity; detecting that additional system resources in the storage system have become available; and issuing an I/O request from an entity-specific queue for an entity that has a highest priority, where a priority for each entity is determined based on the amount of I/O requests associated with the entity and a weighted proportion of resources designated for use by the entity.

Abstract: A method of volume compressed header identification includes reading, by a processing device of a host, compressible data on a sector of a storage volume of a storage array. The method further includes compressing the compressible data to generate compressed data for the sector. The method further includes adding, by the processing device of the host, metadata associated with the storage volume to the compressed data. The method further includes writing the compressed data, including the added metadata, to the sector of the storage volume of the storage array.

Abstract: A method includes compressing data to generate compressed data having a first block size corresponding to a block-size requirement of a client device. The method further includes encrypting the compressed data to generate an encrypted data packet. The method further includes adding, by a processing device, a padding bit pattern to the encrypted data packet to generate a data block for storage, the data block having a second block size determined by a buffer size of a storage array.
