Last Friday I wrote an article about the HP Moonshot (a modern day blade-like system) and why I like it for VDI.
In one of the follow up conversations from that article, Gabe said to me, "Man, did you see that Citrix is doing XenApp bare metal on the Moonshot too?"
While I did notice a XenApp option listed on HP's website when I was researching the article last week, I didn't look into it or think much of it. But today Gabe pointed me to a blog post from Citrix's Tony Sanchez about XenApp on Moonshot, and I've got to say—it's pretty cool.
First, the Moonshot cartridges that they're using are Intel Xeon E3 CPUs with Iris Pro GPUs (rather than the AMD systems on a chip I mentioned last week). Second, when XenApp is used with Moonshot, they're running it on the bare metal—so there's no hypervisor to get in the way of performance or to worry about for compatibility with the GPU and graphics remoting. (That said, I had to laugh when I read Tony's mention of how great it was to have bare metal since you don't have to worry about overcommit and stuff. I mean wasn't that the whole point of virtualization just a few years ago? :)
Anyway this Moonshot thing running XenApp can get 40 to 50 users per cartridge. (Each cartridge is a quad-core Xeon, 32 GB RAM, 100 GB SSD.) The Moonshot chassis holds 45 cartridges in 4.3Us, which works out to 1800-2200ish users per chassis, or roughly 20,000 users per rack.
Yeah, twenty thousand users per rack!
Tony has all sorts of LoginVSI graphs in the post, but the one that really caught my attention was this:
This graph is showing the chassis power consumption (in watts) versus the number of active sessions. If you look closely, you'll see that's pretty darn near 1 watt per user!
This is insane. Did you ever imagine that we'd see the day when we could fit 20,000 medium density users in a single rack with power consumption of only 1 watt per user? (Okay, BriForum attendees who went to Chetan's session should three years ago should have been ready for this. But the rest of this, man, this is crazy.)
So what do you think? Do huge density numbers and low power consumption matter to you? Is this crazily awesome or am I just too far out of it?
