Abstract

Here when we are required to take distributed snapshot of a rack, the Distributed Snapshot Service will generate a snapshot token consisting of the rack identifier and a local timestamp. The generated snapshot token will be forwarded to the spine switch connecting all the different cloud components of the rack. The spine switch of the rack will forward the snapshot token to all different cloud components of the rack and the messages or events that have to be considered for the distributed snapshot will be tagged with the snapshot token by the spine switch. The cloud components of the rack will independently take their snapshots and tag it with the snapshot token and component identifier, and send it to the remote Distributed Snapshot Service.

Description

Distributed Snapshot of Rack
In this invention we provide distributed snapshot of different subsystems of the cloud like virtual switching nodes, virtual compute nodes and virtual storage nodes held by the rack. When we are required to take distributed snapshot of a rack, the Distributed Snapshot Service will generate a snapshot token consisting of the rack identifier and timestamp of the system where the Distributed
Snapshot Service is running. The generated snapshot token will be forwarded to the cloud component consisting of the entry point for the packets of the rack or the spine switch of the rack connecting all the different cloud components of the rack like virtual switching nodes, virtual compute nodes, virtual storage nodes, etc. The spine switch of the rack will forward the snapshot token to all different cloud components of the rack and the messages or events that have to be considered for the distributed snapshot will be tagged with the snapshot token by the spine switch and subsequently other components in the rack will tag the snapshot token as well for events or messages generated due to the above spine switch snapshot token tagged event or message. The cloud components of the rack will independently take their snapshots and tag it with the snapshot token and component identifier, and send it to the remote Distributed Snapshot Service.

Claims

Claims Following is the claim for this invention: -
1. In this invention we provide distributed snapshot of different subsystems of the cloud like virtual switching nodes, virtual compute nodes and virtual storage nodes held by the rack. When we are required to take distributed snapshot of a rack, the Distributed Snapshot Service will generate a snapshot token consisting of the rack identifier and timestamp of the system where the Distributed Snapshot Service is running. The generated snapshot token will be forwarded to the cloud component consisting of the entry point for the packets of the rack or the spine switch of the rack connecting all the different cloud components of the rack like virtual switching nodes, virtual compute nodes, virtual storage nodes, etc. The spine switch of the rack will forward the snapshot token to all different cloud components of the rack and the messages or events that have to be considered for the distributed snapshot will be tagged with the snapshot token by the spine switch and subsequently other components in the rack will tag the snapshot token as well for events or messages generated due to the above spine switch snapshot token tagged event or message. The cloud components of the rack will independently take their snapshots and tag it with the snapshot token and component identifier, and send it to the remote Distributed Snapshot Service. The above novel technique of taking Distributed Snapshot of the rack holding different cloud components is the claim for this invention.
