    Abstract: Systems, methods, and machine-readable media for defining data formats, reflecting system states of managed systems, and managing aspects of those systems via a logically centralized proxy are disclosed. Resources may be represented within a resource provider definition, a package of data format and interaction methods used to instantiate a resource provider, which is a running instance of an executable from the resource provider definition. Users may submit new resource provider definitions, view a list of definitions, and delete definitions. A resource provider service may access the resource provider definition and instantiate a resource provider. The resource provider instance instantiated from the resource provider definition exposes an API, via the resource provider service, to manage data items defined for the resource(s) in the resource provider definition. When the resource is changed, information tracking the state may be updated to reflect the new state of the managed resource.

    Abstract: Techniques are provided for persistent memory file system reconciliation. As part of the persistent memory file system reconciliation, high level file system metadata associated with a persistent memory file system of persistent memory is reconciled. Client access to the persistent memory file system is inaccessible until reconciliation of the high level file system metadata has completed. A first scanner is executed to traverse pages of the persistent memory in order to fix local inconsistencies associated with the pages. A local inconsistency of a first set of metadata or data of a page is fixed using a second set of metadata or data of the page. The first scanner is executed asynchronously in parallel with processing client I/O directed to the persistent memory file system.

    Abstract: A client identifies a first data unit to be shared from a first file to a second file and sends an operation to copy that indicates the first data unit to be shared. The operation to copy the first data unit from the first file to the second file is received. In response to receiving the operation to copy the first data unit from the first file to the second file, it is determined whether the first data unit can be shared with the second file. In response to determining that the first data unit cannot be shared with the second file, the first data unit is copied to the second file. In response to determining that the first data unit can be shared with the second file, the first data unit is shared between the first file and the second file.

    Abstract: Techniques are provided for multi-tier write allocation. A storage system may store data within a multi-tier storage environment comprising a first storage tier (e.g., storage devices maintained by the storage system), a second storage tier (e.g., a remote object store provided by a third party storage provider), and/or other storage tiers. A determination is made that data (e.g., data of a write request received by the storage system) is to be stored within the second storage tier. The data is stored into a staging area of the first storage tier. A second storage tier location identifier, for referencing the data according to a format utilized by the second storage tier, is assigned to the data and provided to a file system hosting the data. The data is then destaged from the staging area into the second storage tier, such as within an object stored within the remote object store.

    Abstract: A technique provides efficient data protection, such as erasure coding, for data blocks of volumes served by storage nodes of a cluster. Data blocks associated with write requests of unpredictable client workload patterns may be compressed. A set of the compressed data blocks may be selected to form a write group and an erasure code may be applied to the group to algorithmically generate one or more encoded blocks in addition to the data blocks. Due to the unpredictability of the data workload patterns, the compressed data blocks may have varying sizes. A pool of the various-sized compressed data blocks may be established and maintained from which the data blocks of the write group are selected. Establishment and maintenance of the pool enables selection of compressed data blocks that are substantially close to the same size and, thus, that require minimal padding.

    Abstract: Systems, methods, and machine-readable media are disclosed for determining an optimal location for creating a new volume (or volumes) on a storage platform and placing the volume at the determined location. A resource tracker collects resource use and/or limits data and stores it in a database. A volume placement service receives a volume deployment specification having constraints for creating a new volume, particularly including instructions relating to relationships between volumes to be created. The volume placement service retrieves the data from the database. The volume placement service identifies an optimal location for the volume based at least in part on given constraints from the specification and the resource usage data. The system places the requested volume at the determined location.
