Abstract: A technique is configured to provide various data protection schemes, such as replication and erasure coding, for data blocks of volumes served by storage nodes of a cluster configured to perform deduplication of the data blocks. Additionally, the technique is configured to ensure that each deduplicated data block complies with data redundancy guarantees of the data protection schemes, while improving storage space of the storage nodes. In order to satisfy the data integrity guarantees while improving available storage space, the storage nodes perform periodic garbage collection for data blocks to optimize storage in accordance with currently applicable data protection schemes

Abstract: A technique provides efficient management of policies for objects of a distributed storage architecture configured to service storage requests issued by one or more clients of a storage cluster. The objects may include volumes for storing data served by storage nodes of the cluster and the policies may include quality of service (QoS) policies. The technique enables dynamic grouping of the volumes as management domains and applying attributes, such as performance settings of the QoS policies, to the management domains. A group of volumes may be organized as a management domain and a QoS policy may be applied to the domain. If membership of the management domain is modified, the QoS policy is automatically applied to the added volume or stripped from the removed volume. If a performance setting of the policy is modified, the modification is atomically applied and propagated to each volume of the management domain.
