Abstract: Exemplary embodiments provide various techniques for managing groups of authenticated entities. In one exemplary computer-implemented method, an entity accesses a group roster that includes a first group identifier identifying a first group, a first group digital certificate associated with the first group, and a first entity identifier identifying the entity being a member of the first group. The entity also receives a request to update the group roster. Here, the request includes a second group identifier identifying a second group and a second group digital certificate associated with the second group. In response to the request, the entity replaces the first group identifier in the group roster with the second group identifier. Additionally, in response to the request, the entity replaces the first group digital certificate with the second group digital certificate. The replacements change a membership of the entity from the first group to the second group.

Abstract: Data storage and management systems can be interconnected as clustered systems to distribute data and operational loading. Further, independent clustered storage systems can be associated to form peered clusters. As provided herein, methods and systems for creating and managing intercluster relationships between independent clustered storage systems, allowing the respective independent clustered storage systems to exchange data and distribute management operations between each other while mitigating administrator involvement. Cluster introduction information is provided on a network interface of one or more nodes in a cluster, and intercluster relationships are created between peer clusters. A relationship can be created by initiating contact with a peer using a logical interface, and respective peers retrieving the introduction information provided on the network interface. Respective peers have a role/profile associated with the provided introduction information, which is mapped to the peers, allowing pre-defined access to respective peers.

Abstract: Exemplary embodiments provide various techniques for the creation and access of quota trees in a file system. In one example, a method of identifying metadata referenced by a quota tree is provided. A quota tree metafile is accessed, and this quota tree metafile includes references to locations of inode grouped data structures associated with quota trees. Here, each quota tree is allocated an inode grouped data structure. A reference to a location of an inode grouped data structure that is allocated to the quota tree is identified from the quota tree metafile. The inode grouped data structure is accessed based on the reference, and this inode grouped data structure defines a set of inode identifiers associated with the quota tree. An inode grouped data structure that stores the metadata is then located using the set of inode identifiers as index

Abstract: A storage system provides highly flexible data layouts that can be tailored to various different applications and use cases. The system defines several types of data containers, including “regions”, “logical extents” and “slabs”. Each region includes one or more logical extents. Allocated to each logical extent is at least part of one or more slabs allocated to the region that includes the extent. Each slab is a set of blocks of storage from one or more physical storage devices. The slabs can be defined from a heterogeneous pool of physical storage. The system also maintains multiple “volumes” above the region layer. Each volume includes one or more logical extents from one or more regions. A foreign LUN can be assimilated into the system by defining slabs as separate portions of the foreign LUN. Layouts of the extents within the regions are not visible to any of the volumes.

Abstract: One or more techniques and/or systems are provided for hosting a virtual machine from a snapshot. In particular, a snapshot of a virtual machine hosted on a primary computing device may be created. The virtual machine may be hosted on a secondary computing device using the snapshot, for example, when a failure of the virtual machine on the primary computing device occurs. If a virtual machine type (format) of the snapshot is not supported by the secondary computing device, then the virtual machine within the snapshot may be converted to a virtual machine type supported by the secondary computing device. In this way, the virtual machine may be operable and/or accessible on the secondary computing device despite the failure. Hosting the virtual machine on the secondary computing device provides, among other things, fault tolerance for the virtual machine and/or applications comprised therein.

Abstract: Some aspects of the disclosure relate to a data storage system that includes multiple memory device storage devices. If a memory device of a memory device array fails within a first data storage device, some portions of the lost or corrupted data from the failed memory device are recovered by reading them from a second data storage device. Other portions of the lost or corrupted data from the failed memory device are recovered from parity information in the first data storage device.

Abstract: A plurality of storage devices is organized into a physical volume called an aggregate, and the aggregate is organized into a global storage space, and a data block is resident on one of the storage devices of the plurality of storage devices. A plurality of virtual volumes is organized within the aggregate and the data block is allocated to a virtual volume. A physical volume block number (pvbn) is selected for the data block from a pvbn space of the aggregate, and virtual volume block number (vvbn) for the data block is selected from a vvbn space of the selected vvol. Both the selected pvbn and the selected vvbn are inserted in a parent block as block pointers to point to the allocated data block on the storage device.
