Abstract: Graph transformations are used by a data management system to correct violations of service-level objectives (SLOs) in a data center. In one aspect, a process is provided to manage a data center by receiving an indication of a violation of a service-level objective associated with the data center from a server in the data center. A graph representation and a transformations data container are retrieved by the data management system from data storage accessible to the data management system. The transformations data container includes one or more transformations. The transformation is processed to create a mutated graph from a data center representation from the graph representation. An option for managing the data center is determined as a result of evaluating the mutated graphs.

Abstract: A machine implemented method and system for allocating a storage volume from among a plurality of storage volumes for storing information in a storage system is provided. The storage system maintains a plurality of groups for segregating the plurality of storage volumes based on storage volume utilization at any given time. A storage volume, when available, is selected from a group that was previously used to select another storage volume. After an end of the group has been reached for allocating the other storage volume, and a threshold value for using the same group to allocate storage volumes has been reached, then another group is used to select the next storage volume.

Abstract: A process for block-level tracking of a sequential data stream that is sub-divided into multiple parts, and stored, by a file system, within non-sequential storage blocks. The process creates block-level metadata as the sequential data stream is written to the storage blocks, wherein the metadata stores pointers to the non-sequential storage blocks used to store the multiple parts of the sequential data stream. This metadata can subsequently be used by a block-level controller to more efficiently read the sequential data stream back to the file system using read-ahead processes.

Abstract translation: 用于块级追踪顺序数据流的过程，其被细分为多个部分，并由文件系统存储在非顺序存储块内。 当顺序数据流被写入存储块时，该过程创建块级元数据，其中元数据存储指向用于存储顺序数据流的多个部分的非顺序存储块的指针。 随后可以由块级控制器使用该元数据，以使用预读过程更有效地将顺序数据流读回到文件系统。

Abstract: A system and method caches and distributes meta-data for one or more data containers stored on a plurality of volumes configured as a striped volume set (SVS) and served by a plurality of nodes interconnected as a cluster. The SVS comprises one meta-data volume (MDV) configured to store a canonical copy of certain meta-data, including access control lists and directories, associated with all data containers stored on the SVS, and one or more data volumes (DV) configured to store, at least, data content of those containers. In addition, for each data container stored on the SVS, one volume is designated a container attribute volume (CAV) and, as such, is configured to store (“cache”) a canonical copy of certain, rapidly-changing attribute meta-data, including time stamps and container length, associated with that container.

Abstract: Methods and apparatuses for efficiently migrating deduplicated data are provided. In one example, a data management system includes a data storage volume, a memory including machine executable instructions, and a computer processor. The data storage volume includes data objects and free storage space. The computer processor executes the instructions to perform deduplication of the data objects and determine migration efficiency metrics for groups of the data objects. Determining the migration efficiency metrics includes determining, for each group, a relationship between the free storage space that will result if the group is migrated from the volume and the resources required to migrate the group from the volume.

Abstract: One or more techniques and/or systems are provided for generating a macroscopic cluster view of storage devices, as opposed to merely an isolated view from an individual node. For example, nodes within a node cluster may be queried for storage device reports comprising storage device information regarding storage devices with which the nodes are respectively connected (e.g., I/O performance statistics, path connections, storage device attributes, status, error history, etc.). The storage device reports may be aggregated together to define one or more storage device data structures (e.g., a storage device data structure comprising one or more tables that may be populated with storage device information). In this way, the cluster view may be generated based upon querying one or more storage device data structures (e.g., an error cluster view, a storage device cluster view, a node summary cluster view, etc.).

Abstract: A service level objective (SLO) subsystem that includes an SLO engine in a network storage system that allows new degrees of freedom to be added to the SLO subsystem, without requiring any modification of an associated SLO engine or the system's existing SLOs, and without requiring the SLO engine to have any a priori knowledge of the new degrees of freedom. In certain embodiments, the system has a modular design which includes the SLO engine and one or more SLO modules that interface with the SLO engine. Each SLO module corresponds to a different degree of freedom. Each SLO module evaluates SLO compliance and determines what specific action(s) within its corresponding degree of freedom should be taken to comply with an SLO.

Abstract: A storage architecture of a storage system environment has a storage connector interface configured to exchange data directly between flash storage devices on a server and a storage array of the environment so as to bypass main memory and a system bus of the server. According to one or more embodiments, the storage connnector interface includes control logic configured to implement the data exchange in accordance with one of a plurality of operational modes that deploy and synchronize the data on the flash storage devices and the storage array. Advantageously, the storage connector interface obviates latencies and bandwidth consumption associated with prior data exchanges over the main memory and bus, thereby enhancing storage architecture performance.
