Did you see the diagram to which I posted a link ? (I didn't show power provisioning for the switches.) I don't think we need dual power supplies for the main servers. If one of the power feeds goes down we can wait to see if it's fixed quickly, and if not fire up the backups of all the VMs on the other server. We're not aiming for 5 nines uptime here - or even 4. IME redundant systems add complexity. I definitely don't think we need battery backup for the switches. If we're running off datacentre power, I would expect to experience more problems due to UPS failure than due to datacentre power failure. So please no in-rack UPS. Thanks, Ian. _______________________________________________ Wg-test-framework mailing list Wg-test-framework@xxxxxxxxxxxxxxxxxxxx http://lists.xenproject.org/cgi-bin/mailman/listinfo/wg-test-framework
