How much did your 20gig of RAM cost you? We don't run 24/7, only when we need to do our experiments. So the power bill is much lower than what a lot of people are worried about. This setup is definitely used on-demand :-)

Also, my setup is a private cloud (in the NIST definition). There are two tenants: myself, and my fiancee. We use VM technology to share the same set of physical resources. Our VMs are managed via Vagrant. VM technology does not imply cloud

I don't believe redundancy, what I think you mean---fault tolerance---is implicit in the definition of cloud computing. The most general form of the term 'cloud' in my mind is elastic access to computational resources. There

Cloud research. Working with modified hypervisor (QEMU), and modified cloud software (OpenStack in my research).

That makes sense. Unless you need, like me, 24-32 GB++ of RAM. Dual HDDs, and a whole lot of cores to run 3-4 VMs at a time. Then the laptop is so resource-poor that it is rendered useless for the workloads I described in the article. This

We are using this server sporadically, essentially wake-on-lan. Especially with the BMC console, we can remotely power it on, off, reset, etc.

And the whole point of the article is cheapness. As in, some people buy old clunker cars and fix them up as a hobby and also sometimes for cheapness. Sure, they pollute more, get less MPG, etc. etc. But they can be dirt cheap, and fun to re

by theonewolf 12y ago
Precisely. We leave it in a more unused space, and the BMC is useful in remotely powering up and checking on it :-)

So the SATA/SAS ports are low enough that the hard drives fit fine in there and connect nicely. They're at a very slight angle. Are you worried about vibration? Or something else? I am a little bit.

Thanks for the tip!

by theonewolf 12y ago
Precisely, you get it. This RAM was _insanely_ cheap :-)

It's pretty fun :-) Also, if you're the real RWMJ, hello :-) I work on introspecting virtual disks with QEMU/KVM (someday hoping to patch QEMU to support my research). We've interacted a few times before.

How much are they with 8 real cores and 24 - 32 GB RAM? And two hard drives?

Sounds awesome :-)

I don't think it's special at all. I work with these things in my cloud research and thought it'd be cute to play around with one at home. Partly because of the challenge at getting an old clunker back into a working state. A

Mine runs at 400W, less at idle. We don't run it 24/7, only when we have some research jobs to run :-)

by theonewolf 12y ago
With my 400W and around 10 cents per kilowatt hour in my area I'm seeing for 750 hours a cost of $30.00 estimated. Now, I do not have this running 24/7. Only when I or she wants to run a research job. So we're talking 8-10 ho

Disk contention? I'm expecting to cache my VM disks in RAM completely while I do my experiments.
80.
by theonewolf 12y ago
I'm assuming now that most of my VMs will be completely cached in my 24 GB RAM.
81.
by theonewolf 12y ago
That's already more expensive than what I paid for the 1U server :-) And I packed in 24 GB RAM for less than $190 (I think $188). Only the HDDs bring the price up, and a couple other accessories, to $300.

First, what I meant, was in its past life it was in a cloud probably. Secondly, I do cloud research. I run a modified KVM/QEMU hypervisor. I run a cloud with features you can not find anywhere else in the world today. So, it is, indeed

by theonewolf 12y ago
It's not just CV, but I get your point.

by theonewolf 12y ago
Yeah, the RAM alone is a costly thing actually. I was lucky to find it so cheap :-)

The CS24-CS isn't so bad. Sounds like a hair drier on low, as others have reported. It's only super loud if you load it (I calculated Pi to 5 billion digits). It would spin up fans, be loud for 30 seconds, and spin down for a few

Au contraire. See the cloudlets concept: http://elijah.cs.cmu.edu/

Fixed. Sorry, I was hosting them myself and keeping them hi-res for the magazine. ACM is fixing something at their end to host them, and at the smaller size.

This guy uses 400W, less at idle. If I could find a cheap desktop with 24-32 GB RAM (again, also cheap, like $60 cheap), than that would be an option.

It's not horrible, sounds like a blow drier on low setting when idling.

I run a customized hypervisor for cloud research. I do things no cloud in the world can currently do. My use case is not a NAS :-)
