I had lunch yesterday with some people who happened to be pretty
familiar with this, and what's dubbed the "hyperscale" paradigm. The
idea is that, instead of some dense servers and running VMs on them,
you go for a massive number of very low-power servers. These Atoms
seem to use something in the ballpark of 10W, but there's also a lot
of interest in ARM chips where you can get much lower usage. And
apparently, 45 nodes in 4.3U is nothing. Look at HP's Redstone[2]
for example, which fit 288 ARM chips into a 4U chassis.
FYI HP Moonshot will support other chip vendors by end of 13, as they
promise (AMD, ARM...)
I've heard some really interesting anecdotes about the density that can
be achieved with ARM chips. It would be interesting to see if things get
even more dense going forward.
I think it's too soon to be able to do a lot, but I think this is
something worth thinking about. Can we effectively bring what we do
in the cloud to "hyperscale" physical nodes?
There is already Foreman which handles bare-metal efficiently. Maybe it
worths to integrate some more effort into the Foreman.
I think that could be a really interesting thing to do... Either with us
integrating with Foreman directly, or trying to get a Foreman driver for
Deltacloud, so that Deltacloud clients can think of it as a "bare metal
cloud."
The Baremetal extension that Kevin Fox mentioned above is also really
interesting -- making bare-metal servers appear behind the OpenStack API.
Between the two of those, it sounds like there is a lot we could do
going forward.
