Abstract

Here we have a multi-ported disk with each port of the storage device or the disk connected to a different storage cluster of n number of virtual machine nodes on the same physical device. Here periodically we take snapshot of the storage cluster along with the snapshot of the disk or for each disk access involving writes we mirror the data on the existing disk by forwarding the periodic snapshot of the storage cluster of n number of virtual machine nodes along with the snapshot of the disk or every disk write to m-1 number of other storage clusters of n number of virtual machines connected to the disk or the storage device via other ports.

Description

Multi-ported Disk for Storage Cluster
In this invention we have a multi-ported disk with each port of the storage device or the disk connected to a different storage cluster of n number of virtual machine nodes on the same physical device. Here periodically we take snapshot of the storage cluster along with the snapshot of the disk or for each disk access involving writes we mirror the data on the existing disk by forwarding the periodic snapshot of the storage cluster of n number of virtual machine nodes along with the snapshot of the disk or every disk write to m-1 number of other storage clusters of n number of virtual machines connected to the disk or the storage device via other ports. This way we do simultaneous data mirroring of the disk or storage device by a factor of m-1 where there are m-1 more storage clusters each of n number of virtual machine nodes connected to it.

Claims

Claims Following is the claim for this invention: -
1 . In this invention we have a multi-ported disk with each port of the storage device or the disk connected to a different storage cluster of n number of virtual machine nodes on the same physical device. Here periodically we take snapshot of the storage cluster along with the snapshot of the disk or for each disk access involving writes we mirror the data on the existing disk by forwarding the periodic snapshot of the storage cluster of n number of virtual machine nodes along with the snapshot of the disk or every disk write to m-1 number of other storage clusters of n number of virtual machines connected to the disk or the storage device via other ports. This way we do simultaneous data mirroring of the disk or storage device by a factor of m-1 where there are m-1 more storage clusters each of n number of virtual machine nodes connected to it. The above novel technique of providing data mirroring of factor of m-1 where there are m ports for a disk or storage device for a storage cluster of n number of virtual machine nodes is the claim for this invention.
