Abstract: A method, system, and computer program product for providing, via a provisioning engine, a scalable set of indexed key-value pairs enabled to store objects in a data storage environment; wherein the data representing the objects is enabled to be spread across arrays in the data storage environment; wherein additional arrays are enabled to be added to the data storage environment and included in the indexed key-value pairs; wherein the data stored across the arrays may be balanced.

Abstract: A computer implemented method, system, and computer program product for enabling strong consistency of unique objects between zones comprising enabling consistency of an unique data object between in zones by switching between consistency techniques to keep the unique data object consistent between the zones; wherein read and write access is enabled to the unique object in the zones.

Abstract: A computer-executable method, computer program product and system for managing metadata in a distributed data storage system, wherein the distributed data storage system includes a first node and one or more data storage arrays, the computer-executable method, computer program product and system comprising partitioning management of metadata created in the distributed data storage system into one or more portions of metadata, wherein the first node manages a first portion of the one or more portions of metadata, and storing the metadata using the first node.

Abstract: A computer-executable method, computer program product, and system for managing backups in a distributed data storage system including a first zone, a second zone, and a third zone, the computer-executable method, computer program product, and system comprising processing, at the third zone, a first portion of data of the first zone and a second portion of data of the second zone to create a combined portion of data, and removing the first portion and second portion from the third zone.

Abstract: Embodiments serve to balance overall performance of a finite-sized caching system having a first cache of a first cache size and a second cache of a second cache size. A tail portion and a head portion of each of the caches are defined wherein incoming data elements are initially stored in a respective head portion and wherein evicted data elements are evicted from a respective tail portion. Performance metrics are defined wherein a performance metric includes a predicted miss cost that would be incurred when replacing an evicted data elements. A quantitative function is defined to include cache performance metrics and a cache reallocation amount. The cache performance metrics are evaluated periodically to determine a then-current cache reallocation amount. The caches can be balanced by increasing the first cache size by the cache reallocation amount and decreasing the second cache size by the cache reallocation amount.

Abstract: A computer-executable method, computer program product, and system for managing metadata within a distributed data storage system, including a compute node in communication with a data storage array, the computer-executable method, computer program product, and system comprising receiving a data I/O from an application executing within the distributed data storage system, and creating a first storage system within the compute node, wherein the first storage system is enabled to manage metadata related to the data I/O, and processing the data I/O using the first storage system.

Abstract: A computer implemented method, computer program product, and system for providing, via a storage provisioning engine, a scalable objects store enabled to store objects across multiple heterogeneous file arrays; wherein file arrays are enabled to be actively added to the object store without pausing the file arrays; and wherein data representing the objects enabled to be balanced across the heterogeneous file arrays based.

Abstract: A computer implemented method, system, and computer program product for enabling consistency between zones comprising creating a lease agreement between a first zone and at least a second zone; wherein the lease indicates that the first zone is the owner of an object; wherein the lease agreement dictates that a notification is to be sent before a cached object in the first zone is updated if the lease is still valid; wherein the lease indicates the first zone is to send a heartbeat to the second zone within the predetermined period of time if the object has not been changed and the lease is still valid; and setting up heartbeats from the first zone to at least a second zone within a predetermined amount of time; wherein the heartbeat indicates that the lease is still valid and the object has not been changed.

Abstract: In one aspect, a method includes using a file system layer configured to interact with a plurality of volumes and enabling an application to interact with any of the plurality of volumes using a single file system format provided by the file system layer. At least two of the plurality of volumes have different file system formats.

Abstract: In one aspect, a method includes enabling a REST interface to have access to a volume, receiving a request to allow a native file access to the volume and allowing an application to use a native file interface to have access to the volume while preventing the modifications to the volume through the REST interface if the request is received.
