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: Described herein is a system and method for a scalable crash-consistent snapshot operation. Write requests may be received from an application and a snapshot creation request may further be received. Write requests received before the snapshot creation request may be associated with pre-snapshot tags and write requests received after the snapshot creation request may be associated with post-snapshot tags. Furthermore, in response to the snapshot creation request, logical interfaces may begin to be switched from a pre-snapshot configuration to a post-snapshot configuration. The snapshot may then be created based on the pre-snapshot write requests and the post-snapshot write requests may be suspended until the logical interfaces have switched configuration.

Abstract: Technology is disclosed for managing data in a distributed file system (“the technology”). The technology can gather metadata information associated with the data stored within the distributed file system, create a secondary namespace within a local file system of a local host using the gathered metadata information and store the gathered metadata information as files within the secondary namespace. Further, when a request to create a PPI of the distributed file system is received, the technology can create a PPI of the secondary namespace using a PPI creation feature of the local file system.

Abstract: Embodiments described herein provide an object store that efficiently manages and services objects for use by clients of a distributed data processing system. Illustratively, the object store may be embodied as a quasi-shared storage system that interacts with nodes of the distributed data processing system to service the objects as blocks of data stored on a plurality of storage devices, such as disks, of the storage system. To that end, an architecture of the object store may include an on-disk layout, e.g., of the storage system, and an incore layout, e.g., of the nodes, that cooperate to illustratively convert the blocks to objects for access by the clients.

Abstract: A network storage server system includes a distributed object store and a metadata subsystem. The metadata subsystem stores metadata relating to the stored data objects and allows data objects to be located and retrieved easily via user-specified search queries. It manages and allows searches on at least three categories of metadata via the same user interface and technique. These categories include user-specified metadata, inferred metadata and system-defined metadata. Search queries for the metadata can include multi-predicate queries.

Abstract: A system and method for helping customers install a modular computing system is provided. In some embodiments, the method comprises determining, using a computing system, whether all components of a modular computing system have been received by a customer. Based on determining that not all the components of the modular computing system have been received by the customer, it is determined whether the modular computing system can be incrementally deployed. A customer instruction for incrementally deploying the modular computing system is provided at a display device. A communication link is established with a component of the modular computing system. Communications directed over the communication link are used to determine whether a customer correctly performed the provided customer instruction. In one such embodiment, the determining of whether the modular computing system can be incrementally deployed includes determining whether a minimum resource requirement is met.

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.
