Abstract

There is disclosed a method for writing data in a data storage system comprising a plurality of data storage nodes, the method being employed in a server running an application which accesses data in the data storage system, and comprising: sending a multicast storage query to a plurality of said storage nodes; receiving a plurality of responses from a subset of said storage nodes, said responses including a storage node property; selecting at least two storage nodes in the subset for storing said data, based on said responses, wherein the selecting is based on a data property of the data to be stored and a storage node property.

Claims

1. A method for writing data in a data storage system including a plurality of storage nodes, from a server which accesses data in the data storage system, the method comprising:

sending a multicast storage query to the plurality of storage nodes;

receiving a plurality of responses from a subset of said plurality of storage nodes, each of said responses including a storage node property; and

selecting at least two storage nodes in the subset for storing said data based on said responses, wherein the selecting is based on a data property of the data to be stored and the storage node property of the at least two storage nodes in the subset.

2. The method according to claim 1, wherein said node property includes at least one of:

a type of disk, a response time, a redundancy configuration, a reliability, a node environment, a territory, or an energy consumption.

3. The method according to claim 1, wherein the server associates the received data property with at least one storage node property, and the selection of the at least two storage nodes in the subset is based on the association.

4. The method according to claim 1, wherein the data property corresponds to a type of user that created or edited the data.

5. The method according to claim 1, wherein the data property is a file type.

6. A method for writing data in a data storage system, the data storage system including a plurality of storage nodes, the method employed in a server that accesses data in the data storage system, the method comprising:

selecting a set of storage node properties based on a data property of the data to be stored;

sending a multicast storage query to the plurality of storage nodes, said storage query including an indication of the set of storage node properties;

receiving a plurality of responses from a subset of the plurality of storage nodes, wherein the subset storage nodes comply with requirements of the set of storage node properties; and

selecting at least two storage nodes in the subset for storing said data based on the responses.

7. The method according to claim 6, wherein said set of node properties include at least two of:

a type of disk, a response time, a redundancy configuration, a reliability, a node environment, a territory, or an energy consumption.

8. The method according to claim 6, wherein the data property corresponds to a type of user that created or edited the data.

9. The method according to claim 6, wherein the data property is a file type.

10. A device, the device included in a server, the device configured to access and write data to a data storage system, the data storage system including a plurality of storage nodes, the device configured to:

send a multicast storage query to a plurality of storage nodes;

receive a plurality of responses from a subset of said plurality of storage nodes, each of said responses including a storage node property; and

select at least two storage nodes in the subset for storing said data based on said responses, wherein the selecting is based on a data property of the data to be stored and the storage node property of the at least two storage nodes in the subset.

11. The device according to claim 10, wherein said node property includes at least one of:

a type of disk, a response time, a redundancy configuration, a reliability, a node environment, a territory, or an energy consumption.

12. The device according to claim 10, wherein the device is further configured to associate the received data property with at least one storage node property, and select the at least two storage nodes in the subset is based on the association.

13. The device according to claim 10, wherein the data property corresponds to a type of user that created or edited the data.

14. The device according to claim 10, wherein the data property is a file type.
