    Abstract: A method and system for a provisioning advisor are described which estimates the input/output operation performance of a workload on a storage system. A regression module in a provisioning advisor estimates a maximum IOPS on the storage system for buckets, or combinations of values, for various characteristics of the workloads running on the system by modeling a relationship between the workload characteristics and performance metrics gathered from the storage system. A performance module can use the estimated maximum IOPS for each bucket to update a set of working tables for the provisioning advisor, which can then be used to predict the input/output performance of a new workload to be provisioned on the storage system.

    Abstract: To leverage the attributes of object storage for applications/systems created to interface with a network files system, an object storage backed file system can accept the defined file system commands from the applications/systems and transform the file system commands into requests that target object storage. The file system is “backed” by object storage because attributes and content of file system entities are stored in objects. For instance, content data and metadata of a file are stored in objects in object storage. This object storage backed file system can be considered a bridge between a client perceived hierarchical file system namespace and a flat namespace of an object storage.

    Abstract: A system and method for planning and configuring the components of a modular computing system is provided. In some embodiments, the method for planning an implementation of a modular computing system comprises presenting a user interface at a display device, the user interface including a plurality of user-selectable objects, each of the user-selectable objects representing a component of the modular computing system. A user selection is received via a user input device. The user selection is from among the user-selectable objects and specifies one of an enclosure, an existing component, and a future component of the modular computing system. A representation of the specified one of an enclosure, an existing component, and a future component is displayed at a display device. The user selection is verified with respect to an implementation guideline. An indicator of whether the user selection meets the implementation guideline is displayed at the display device.

    Abstract: During a storage redundancy giveback from a first node to a second node following a storage redundancy takeover from the second node by the first node, the second node is initialized in part by receiving a node identification indicator from the second node. The node identification indicator is included in a node advertisement message sent by the second node during a giveback wait phase of the storage redundancy giveback. The node identification indicator includes an intra-cluster node connectivity identifier that is used by the first node to determine whether the second node is an intra-cluster takeover partner. In response to determining that the second node is an intra-cluster takeover partner, the first node completes the giveback of storage resources to the second node.

    Abstract: A method, non-transitory computer readable medium, and computing device that determines when a software failure associated with a virtual storage controller has occurred. At least a portion of a transaction log corresponding to the virtual storage controller is stored in a stable storage device, when the determining indicates that the software failure associated with the virtual storage controller has occurred. A determination is made when the virtual storage controller has rebooted. The at least a portion of the transaction log is retrieved from the stable storage device, when the determining indicates that the virtual storage controller has rebooted. Thereby, state can be preserved and transactions pending, but not yet committed to storage server devices, can be replayed and proceed with minimal or no impact on the client devices originating the transactions.

    Abstract: Presented herein are mass data storage systems, file system protocols, non-transitory machine readable devices, and methods for storing data blocks in data file systems. Methods for compressing snapshot data in a data file system are disclosed which include: loading a snapshot file with one or more data blocks, the snapshot representing a state of the data file system at a point in time; determining if at least one of the snapshot data blocks is less than a predetermined byte value; responsive to a snapshot data block having a size that is less than the predetermined byte value, identifying a packed block configured to store data chunks from plural distinct snapshots and having available sufficient storage space to store the snapshot data block; and adding to the packed block the snapshot data block and lost-write context information corresponding to the snapshot data block.
