Abstract

An apparatus and a method operating on data at a server node of a data grid system with distributed cache. Data is copied to a network cloud of storage services remotely coupled to a server node with an asynchronous input output interface. The asynchronous input output interface is configured to asynchronously communicate with the network cloud of storage services. Confirmation that the data has been copied on the network cloud of storage services is received at the server node.

Claims

1. A computer-implemented method comprising:

operating, by a server in a data grid system, on data in the data grid system, the server comprising a processing device and an asynchronous input output interface, wherein the data grid system is compatible with a distributed cache;

copying, by the asynchronous input output interface, the data to a network cloud of storage services remotely coupled to the server, the asynchronous input output interface to asynchronously communicate with the network cloud of storage services; and

receiving, by the server in the data grid system, confirmation that the data has been copied on the network cloud of storage services by the asynchronous input output interface;

wherein the data grid system comprises a network of servers forming a cluster of caches, each cache replicated to a limited number of caches in the cluster of caches, each server associated with one or more caches.

2. The computer-implemented method of claim 1 wherein the asynchronous input output interface is to enable the server to perform at least one other operation at the server pending copying the data to the network cloud of storage services.

3. The computer-implemented method of claim 1 wherein the data grid system comprises a concurrent distributed data structure.

4. The computer-implemented method of claim 3 further comprising:

replicating the data to at least one other server in the data grid system.

5. The computer-implemented method of claim 1 further comprising:

receiving a request to operate on the data from a client; and

returning a result of the operation on the data to the client.

6. The computer-implemented method of claim 1 wherein the data grid system operates on a single server or a plurality of servers.

7. A non-transitory computer-readable storage medium, having instructions stored therein, which when executed, cause a computer system to perform a method comprising:

operating, by a server in a data grid system, on data in a data grid system, the server comprising a processing device and an asynchronous input output interface, wherein the data grid system is compatible with a distributed cache;

copying, by the asynchronous input output interface, the data to a network cloud of storage services remotely coupled to the server, the asynchronous input output interface to asynchronously communicate with the network cloud of storage services; and

receiving, by the server in the data grid system, confirmation that the data has been copied on the network cloud of storage services by the asynchronous input output interface;

wherein the data grid system comprises a network of servers forming a cluster of caches, each cache replicated to a limited number of caches in the cluster of caches, each server associated with one or more caches.

8. The non-transitory computer-readable storage medium of claim 7 wherein the asynchronous input output interface is to enable the server to perform at least one other operation at the server pending copying the data to the network cloud of storage services.

9. The non-transitory computer-readable storage medium of claim 7 wherein the data grid system comprises a concurrent distributed data structure.

10. The non-transitory computer-readable storage medium of claim 9 wherein the method further comprises:

replicating the data to at least one other server in the data grid system.

11. The non-transitory computer-readable storage medium of claim 7 wherein the method further comprises:

receiving a request to operate on the data from a client; and

returning a result of the operation on the data to the client.

12. The non-transitory computer-readable storage medium of claim 7 wherein the data grid system operates on a single server or a plurality of servers.

13. A computer system comprising:

a memory;

a processor coupled to the memory, the processor to operate on data in a data grid system, wherein the data grid system comprises a server and is compatible with a distributed cache; and

an asynchronous input output interface coupled to the processor, the asynchronous input output interface to copy the data to a network cloud of storage services remotely coupled to the server, the asynchronous input output interface to asynchronously communicate with the network cloud of storage services, and to receive confirmation that the data has been copied on the network cloud of storage services by the asynchronous input output interface;

wherein the data grid system comprises a network of servers forming a cluster of caches, each cache replicated to a limited number of caches in the cluster of caches, each server associated with one or more caches.

14. The computer system of claim 13 wherein the asynchronous input output interface is to enable the server to perform at least one other operation at the server pending copying the data to the network cloud of storage services.

15. The computer system of claim 13 wherein the data grid system comprises a concurrent distributed data structure.

16. The computer system of claim 15 wherein the data is replicated to at least one other server in the data grid system.

17. The computer system of claim 13 wherein the asynchronous input output interface is to receive a request to operate on the data from a client, and to return a result of the operation on the data to the client.
