Abstract

A clustered system arranged for supporting a clustered file system. The clustered system comprises at least two nodes and is characterised in that these at least two nodes are arranged for exchanging data traffic of the clustered file system between each other via an IP protocol over a lossless Ethernet network.

Claims

1. A clustered system arranged for supporting a clustered file system, said clustered system comprising at least two nodes, wherein said at least two nodes are arranged for exchanging data traffic of said clustered file system between each other via an IP protocol over a lossless Ethernet network.

2. The clustered system as in claim 1, wherein said lossless Ethernet network is a Data Center Ethernet based network.

3. The clustered system as in claim 1, wherein said lossless Ethernet network is arranged for applying a Priority Flow Control mechanism to map different data traffic flows on a plurality of lossless IP over Ethernet traffic classes, providing said different data traffic flows an independent flow control mechanism.

4. The clustered system as in claim 1, wherein at least one of said nodes is a storage node arranged for storing at least a part of said clustered file system.

5. The clustered system as in claim 4, wherein said storage node comprises local storage means.

6. The clustered system as in claim 4, wherein said storage node is arranged for being connected to external storage means.

7. The clustered system as in claim 1, wherein at least one of said nodes is arranged for exchanging said data traffic with an external device.

8. The clustered system as in claim 4, further comprising a node arranged for exchanging said data traffic with an external device, said node further arranged for running on a different operating system than said storage node.

9. The clustered system as in claim 7, wherein said at least one node is arranged for exchanging said data traffic with an external device via a lossless Ethernet connection.

10. The clustered system as in claim 9, wherein said lossless Ethernet connection is a part of said lossless Ethernet network.

11. The clustered system as in claim 7, wherein said external device is a high resolution editing client.

12. The clustered system as in claim 1, wherein at least one of said nodes comprises processing means for media applications.

13. An assembly of at least two clustered systems as in claim 1, whereby said at least two clustered systems are arranged for exchanging data traffic of at least one of the clustered file systems via an IP protocol over a dedicated lossless Ethernet network.

14. The assembly as in claim 13, wherein said dedicated lossless Ethernet network is a DataCenter Ethernet based network.

15. The assembly as in claim 13, wherein said dedicated network is at least part of the lossless Ethernet network of at least one of said at least two clustered systems.
