Systems, methods, and machine-readable media are disclosed for collecting, maintaining, and retrieving use and limit data for connected resources, as well as determining an optimal location for creating a new volume (or volumes) on a storage platform and placing the volume at the determined location. A resource tracker collects resource use and/or limits data and stores it in a database. A volume placement service receives a volume deployment specification having constraints for creating a new volume. The volume placement service retrieves the data from the database. The volume placement service identifies an optimal location for the volume based at least in part on given constraints from the specification and the resource usage data. The system places the requested volume at the determined location.

Volume placement based on resource usage

Decoupling volume deployment requirements and code implementation

A method for centralized storage and management of resource data associated with storage servers includes operating multiple storage servers, each configured to provide a set of clients with access to data stored in a set of mass storage devices, and using a directory server, which is coupled to the storage servers via a network. The directory server stores and provides access to configuration information for configuring the plurality of storage servers.

Centralized storage of storage system resource data using a directory server

Caching of data requests in session-based environment. An embodiment of a method includes a client preparing a data request for a storage server in a session-based environment. The prepared data request is transmitted from the client to the storage server. The data request is stored in a cache memory for the client via a protocol for the session-based environment.

Caching of data requests in session-based environment

Non-disruptive server replacement for session-based clients. An embodiment of a method includes establishing a first session between a first storage server and a client, the first storage server comprising a data component coupled to a data storage, a network component, and a session data structure in the network component for the first session. Transferring an operation of the first storage server to a second storage server during the first session with the client, wherein the second storage server is a replacement storage server for the first storage server.

Non-disruptive server replacement for session-based clients

Non-disruptive server replacement for session-based clients. An embodiment of a method includes establishment of a session between a storage server and a client, with the storage server including a session data structure for the session, and transferring an operation of the storage server to a replacement storage server. Transferring the operation of the storage server includes generating an image the session data structure and placing the image in the replacement storage server, transferring operation of the session data structure in the storage server to the image of the session data structure in the replacement storage server, and transferring a network address of the storage server to the replacement storage server.

Non-disruptive server replacement for server-based clients

A method for storage of user mapping data associated with users of data stored by storage servers includes operating multiple storage servers, each configured to provide a set of clients with access to data stored in a set of mass storage devices, and using one or more directory servers, which may be coupled to the storage servers via a network. The directory server stores and provides access to user account information associated with a second operating system based on user account information associated with a first operating system, when the user account information associated with the second operating system is needed to access data stored in accordance with the second operating system.
