    摘要: Ensuring the fair utilization of system resources using workload based, time-independent scheduling, including: determining whether an amount of available system resources in the storage system has reached a predetermined reservation threshold; and responsive to determining that the amount of available system resources in the storage system has reached the predetermined reservation threshold: determining whether one or more entities in the storage system have utilized system resources in excess of their fair share by a predetermined threshold during one or more time-independent periods; and responsive to determining that one or more entities in the storage system have utilized system resources in excess of their fair share by the predetermined threshold during the time-independent period, limiting the one or more entities from issuing additional I/O requests to the storage system.

    摘要: 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.

    摘要: Protecting an encryption key for data stored in a storage system that includes a plurality of storage devices, including: reading, from at least a majority of the storage devices, a portion of an apartment key; reconstructing the apartment key using the portions of the apartment key read by the majority of the storage devices; unlocking the main portion of each of the storage devices utilizing the apartment key; reading, from the main portion of one of the storage devices, a portion of a third-party resource access key; requesting, from the third-party resource utilizing the third-party resource access key, an encryption key; receiving, from the third-party resource, the encryption key; and decrypting the data stored on the storage devices utilizing the encryption key.
