Open Stack

Hi Simon and Hitesh,

I've started a spec on cloud PM some times ago, that you may be interesting
in reading:
https://blueprints.launchpad.net/ubuntu/+spec/servercloud-p-cloud-power-management

It's incomplete, but most ideas are there.
The base ideas are that:
- you can't just consider power efficiency, without power availability and
cost,
- PUE must also be considered for the whole infrastructure. So it's not
just about optimizing 1 server load, but also which server (WRT for example
UPS efficiency, or its power status, Ie online/on battery),
- using the deployed power protection system maximize visibility and
features, by using the data from the power devices,
- the NUT (networkupstools.org) can provide both this protection and
visibility, by supporting all types of power devices out there (UPS, PDU,
server power supplies, and soon smart meters).

FYI, NUT is also bundled in all Linux, available for all systems, and
embedded in tons of NAS and appliances found in DC...

>From my first discussions with Jay, it seemed that local integration of NUT
in Nova + a new scheduler (that has the global visibility) is the way to go.

I also came to the conclusion that it was worth creating a power QOS API,
that could be supported by any cloud OS, and implemented by internal or 3rd
party solution.

Cheers,
Arnaud
