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.

Optimizing I/O operations for compressed data

A method of scheduling input/output operations for a storage system including determining a deadline for a storage operation, wherein the deadline is dependent on an expected latency of the storage operation; adding the storage operation to a queue of storage operations; and reordering the queue dependent upon the deadline of the storage operation and one or more deadlines of one or more storage operations in the queue of storage operations.

Queueing storage operations

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.

Sizing a virtual storage system

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.

Optimizing data reduction for data in encrypted volumes

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.

Time-independent scheduling of storage operations

Performing disaster recovery in a cloud-based storage system, including: creating, by a storage system a snapshot of a dataset; uploading, from the storage system to a cloud computing environment, the snapshot; storing, by the cloud computing environment, the snapshot; detecting, by the cloud computing environment, that the dataset is not available on the storage system; and creating, by the cloud computing environment using the snapshot that is stored within the cloud computing environment, a cloud-based storage system that includes the dataset.

Creating cloud-based storage systems using stored datasets

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.

Encryption in a storage array

Preserving identities and policies across replication, including: receiving, at a first storage array, a first data frame comprising data associated a dataset stored at the first storage array and an identifier of a quality of service level associated with the first data frame; generating, at the first storage array, a second data frame comprising a portion of the dataset and the identifier of the quality of service level associated with the first data frame; and transmitting the second data frame to a second storage array.

Preserving identities and policies across replication

A method of modifying encryption of a storage system includes: receiving an instruction to rekey data on a storage system, wherein the instruction identifies first encryption information and second encryption information; determining that the instruction is authorized; decrypting, by a processing device of a storage system controller, the data using a current key included in the first encryption information to generate decrypted data; and encrypting, by the processing device of the storage system controller, the decrypted data using the second encryption information to generate encrypted data.

Modifying encryption in a storage system

Cloning storage systems in a cloud computing environment, including: receiving a request to create a cloud-based storage system; retrieving, from cloud-based object storage, one or more objects to include in the cloud-based storage system; and creating the cloud-based storage system, including storing, in block storage of the cloud-based storage system, data contained in the one or more objects retrieved from the cloud-based object storage.

System resource management using time-independent scheduling

Workload planning with quality-of-service ('QoS') integration, including: determining, for each of a plurality of entities, one or more QoS thresholds associated with the entity; determining, for each of the plurality of entities, one or more resource utilization levels associated with the entity; and determining, in dependence upon the one or more QoS thresholds associated with the plurality of entities, the one or more resource utilization levels associated with the plurality of entities, and one or more overprovisioning factors associated with the storage system, a risk factor that identifies the likelihood that one or more system resources will be overconsumed by the plurality of entities.
