VMWare is joining the InteropNET team again this year and helping the NOC to be a bit greener, while increasing the overall reliability of the network services we’re providing. The overall concept is that we create virtual machines just like you would sysgen a normal machine, but instead of installing directly to the metal (i.e. installing onto a new physical server) this time you’re installing under the VMWare management system. These images can be started, stopped, paused or moved depending upon the business rules you’ve defined. We just happen to be running our virtual machines (VM’s) on a blade server, but you could just as easily run them on a mixed bag of legacy servers that you already have. In fact, I’ve been consulting with a couple credit unions on using VMware to leverage their existing infrastructure while still expanding the types of services they provide.
Heck, add in a Coyote Point load balancer and you can load balance, auto-stop/start VM’s and all kinds of stuff. Sure is sounding like a greener future.
This diagram shows how the VMWare virtual infrastructure provides a way to share resources, but the real story is just how green this really is. Ok here’s the story: take a good hard look at your web servers. I betcha they’re probably only running in the 7-20% utilization range. Now look around the back and they might be using anywhere from 700watts all the way up to monsters sucking down over a 1500watts. Now consider this, even the new energy star power supplies don’t reach maximum efficiency loafing along…they actually get more efficient as the load goes up.
Now what if we take those very same servers, toss on a virtualization layer, and now run say a half dozen web servers on it? Each project group (assuming each project group owns their own web server) still gets roots access to “their server” and can still patch it and add to it as they see fit. However, now with a half dozen servers running, the underlying server is now probably running into the 60-70% range….aaaahhhh…much more efficient and we’ve just turned off perhaps as many as five 700watt power supplies. VERY GREEN.
Green enough that Pacific Gas and Electric has an incentive program going to help folks jump into virtualizing their environment, AND save a whole heck of a lot of bucks.
While I didn’t manage to snag some video of the VMWare engineers while at hotstage, VMWare does have some mighty fine podscasts talking about the technology.
