The CMS online Cloud

Another milestone has been achieved. We were able to setup the two bonded 10Gbit links through the “data networks” to serve the cloud with minimal changes on the existing infrastructure.

We configured the networks at the level of the router/switches/hypervisors, and we used OpenvSwitch to redirect the flow (and change the MAC Address of the gateway for this flow) to specific computers, where traffic goes, through the high bandwidth network we have.┬áThis means that without a modification on the side of the VMs, they will be using our high bandwidth network to talk to the “data providing” computers.
