The disclosure relates improving the efficiency of networked storage systems in time and space.
Background: Referring now to the figures, both
A projected data store 181 is a virtualization of said data store 111 in that it emulates behavior without having the same physical structure. This is modernized by utilizing cloud services. But it could simply be two private data centers communicatively coupled.
A database 191 is anything that can provide at least {key,value} semantics. For the purpose of the present patent application it may be logically constructed of any one of conventional database technologies on any physical non-transitory media operated by a cloud service provider.
The invention is a system (Virtual Remote Holodeck) which includes a file operation request interceptor, a controller, and an accessor. These couple a 1st data store, a database situated away from the 1st data store, and a projected data store which is a virtualization of said 1st data store.
In the method of the invention, when a program makes a file request, for example a file read, an interceptor analyzes the request with respect to meta data of a projected data store and calls a controller to satisfy it as follows. In the case of a read it first looks in the database to see if it can be completed in whole or in part with the information already stored there. For any part that cannot be satisfied within the cloud service, the controller makes a request of the accessor for the missing parts. The accessor will get what is needed from the legacy data store on premises and send it to back to the controller. The controller will store this new information into the database for future use. It then assembles everything needed for the originating request and send it back to the interceptor to complete the operation.
A remote accessor apparatus captures a state of an existing data store and exports the state to a hosted projected data store. When a file operation interceptor apparatus receives a request, it determines whether it requires a transmission from the existing data store or it can be fulfilled locally. An operation controller combines local and transmitted data to fulfill the requested file operation and stores the difference locally. On-demand, read/write requests are intercepted and fulfilled by a combination of locally provisioned file content operations and remote access requests to the agent apparatus in whole or in part. Upon first request, file contents are transferred to meet application need but are then retained for other users and other uses.
Upon request, a new state for the existing data store is provided by combining archived data with local file operations. In a further improvement, the system returns only changed items to the 1st data store upon request, whereby unnecessary data communication is minimized.
The foregoing and other objects, aspects, features, and advantages of the disclosure will become more apparent and better understood by referring to the following description taken in conjunction with the accompanying drawings, in which:
As is known, cloud-based services for data and compute scale attractively and dynamically respond to varying requirements. However, wholesale transfer of large datasets related to enterprise level projects are inefficient and uneconomical. And even piecemeal uploading and downloading of file systems is frustrated by undocumented dependencies and limited bandwidth.
One aspect of the invention shown in
In systems 100 and 101, said Operation Controller 140 is further coupled to a Database 191 and to a File Operation Interceptor 170. The File Operation Interceptor is further enabled to read the stored projected data store 181 which tracks the state of the contents of the Legacy Data Store 111. The File Operation Interceptor receives file operation requests and fulfills them.
Another aspect of the invention shown in
At a remote accessor apparatus, the method 200 comprises: determining a state for contents of the existing data store 210; opening a communication connection to an operation controller 214; transmitting state for storage in a projected data store 216, and fulfilling file operations requested by the operation controller to read and write contents into the data store 290.
At a file operation interceptor, the method 200 comprises: receiving a file operation request from a processor 270; determining from state stored in the projected data store a location for data within the data store 272; transmitting said file operation request with location to an operation controller 274; receiving a response from the operation controller 276; and returning the response to the requesting processor 278.
At an operation controller, the method 200 comprises: receiving state of a legacy data store from an accessor and storing it non-transitory computer-readable media 240; receiving a file operation request from an interceptor 242; determining when data content is local to an accessor 244; determining when data content is stored locally in a database 246; combining and transmitting data content in fulfillment of the file operation request 248.
Aspects of the invention can be appreciated as methods, apparatuses, and systems combining such methods and apparatuses.

Upon first request, file contents are transferred to meet application need but are then retained for other users and other uses. Upon request, a new state for the existing data store is provided by combining archived data with local file operations.
