Abstract

A grid application and storage system to enhance data access. The grid application and storage system comprises a plurality of grid application storage nodes with at least one storage system, said grid application storage nodes being remote to each other and connected via inter-connections; at least one application process distributed across said grid application storage nodes; and at least one grid node control process also distributed across said grid application storage nodes, said grid node control process managing grid application storage node operations. A plurality of client systems are connected to said grid application and storage system via a network for deploying said application process and accessing application data stored on said grid application storage nodes.

Claims

1. A method for storing application data in a grid application and storage system, said grid application and storage system comprising

a plurality of grid application storage nodes with at least one storage system, said grid application storage nodes being remote to each other and connected via inter-connections;

at least one application process distributed across said grid application storage nodes; and

at least one grid node control process also distributed across said grid application storage nodes, said grid node control process managing grid application storage node operations;

wherein a plurality of client systems are connected to said grid application and storage system via a network for deploying said application process and accessing application data stored on said grid application storage nodes;

said method being characterized

by determining the location of at least one client system defined for accessing the application data to be stored,

by determining the location of at least a subset of the grid application storage nodes of said grid application and storage system, and

by storing said application data on at least one selected grid application storage node of said subset, wherein the selection is based on the relation between the location of said client system and the locations of the grid application storage nodes of said subset.

2. The method according to claim 1, wherein the location of the accessing client system represents a user'"'"'s current location and is determined automatically on the base of the TCPIP address, the MAC address or the name of said client system.

3. The method according to claim 1, wherein the location of the accessing client system represents a user'"'"'s future location and is determined on the base of user travel information provided said via said network.

4. The method according to claim 1, wherein the criteria for selecting grid application storage nodes for storing given application data comprise:

a maximum distance between the accessing client system and a grid application storage node to be selected.

5. The method according to claim 4, wherein the criteria for selecting grid application storage nodes for storing given application data further comprise:

the number of grid application storage nodes to be selected with write/read-authority for the application data to be stored and

the number of grid application storage nodes with only read-authority for the application data to be stored.

8. The method according to claim 1, wherein application data stored on a given grid application storage node is transferred to at least one distant grid application storage node automatically, wherein the selection of said distant grid application storage node is based on the relation between its location and the location of at least one client system defined for accessing said application data.

9. The method according to claim 8, wherein said selected distant grid application storage node is provided with write/read authority for the application data to be transferred.

10. The method according to claim 8, wherein the user location is monitored when accessing given application data and wherein the transfer of said application data is initiated automatically whenever a change of the user location is determined.

11. The method according to claim 8, wherein the transfer of application data is triggered by user travel information provided via said network.

12. An infrastructure for storing application data in a grid application and storage system, said grid application and storage system comprising

a plurality of grid application storage nodes with at least one storage system, said grid application storage nodes being remote to each other and connected via inter-connections;

at least one application process distributed across said grid application storage nodes; and

at least one grid node control process also distributed across said grid application storage nodes, said grid node control process managing grid application storage node operations;

wherein a plurality of client systems are connected to said grid application and storage system via a network for deploying said application process and accessing application data stored on said grid application storage nodes;

said infrastructure being characterized

by means for determining the location of at least one client system defined for accessing the application data to be stored, said means comprising a user'"'"'s electronic calendar and travel system connected to network,

by means for determining the location of at least a subset of the grid application storage nodes of said grid application and storage system, and

by means for storing said application data on at least one selected grid application storage node of said subset, wherein the selection is based on the relation between the location of said client system and the locations of the grid application storage nodes of said subset.
