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.

Scalable index store

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.

Distributed metadata management

A computer-executable method, computer program product, and system of managing I/O requests in a distributed data storage system, wherein the distributed data storage system includes a first node and one or more data storage array, the computer-executable method, computer program product, and system comprising receiving an I/O request at the first node enabled to utilize a storage engine to process the I/O request, wherein the storage engine is comprised of two or more layers, analyzing the I/O request using a first layer of the two or more layers to determine whether the I/O request relates to a portion of metadata managed by the first layer of the two or more layers, and processing the I/O request based on the determination.

Distributed data storage management

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.

Scalable distributed storage system infrastructure

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.

File system layer

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.

Native file access

HVAC apparatus is configured to include a control system with a controller which may be connected directly to a personality module for transferring information stored in the controller related to historic operating conditions of the apparatus to the module, or information may be transferred to the controller from the module to configure the controller for operation of the apparatus at selected operating conditions of temperature, pressure and blower motor speed, for example. The personality module includes a memory circuit and a connector for releasably connecting the module to the control system of the apparatus for transferring information between the module and the controller.
