This is entirely a rant, and only tangentially instructional. It is related to the virtualization malarkey I’m doing at the moment, but won’t actually help anyone set up a similar infrastructure. It might save someone a bit of brain-ache in the future, but mostly, I’m just annoyed.
To recap briefly: I want shiny new virtual servers in a high-availability cluster, and to do that, I have 2 beefy DL380 G7s and a single DL160 G6 to act as a physical DC and administer the VMs. There’s

I've checked all hardware, chosen the OS [Debian] and the MPI [OPEN-MPI], I've got a bit of documentation so I know what I'm doing [slightly].
But there's one thing I forgot to check...
CHECK THERE'S ENOUGH ROOM!!
Which there isn't... Blargh!
I'm still doing it though. A couple of powerstrips [and a reposition of the laptop trolley] should be sufficient.
As usual, any suggestions let me know.

This blog post comes courtesy of a thread elsewhere on Edugeek as well as ideas brought up from one of the schools I support.
I'll start small. A couple of weeks ago, one of my HT's attended training at a local academy. This academy rolled out iPads for all it's pupils. Naturally he liked the look of this but with a diminutive budget, asked what I could do along the same sort of lines but for half a class.
The logistics were easy enough, just under £6k buys 16 ipads, a dock/box/sync/charger
Cluster server is go.
At least premission has been given, and the powers that be think the LAN MMO idea is a good one. [Still trying to find one... here's hoping BETT can help.]
For those who are curious, for this experiment I will be using:
10 RM F-series as nodes [Which I can't find full specs for...]
Some sort of ex-admin Dell as the controller. We've got a couple sitting about.
Cisco Catalyst 2950 [24

This is the start of a lot of writing, because if I put it down in words, it'll make me believe that I'm in control and I know what I'm doing. I promise you, I'm not and I don't. Most of this will be disjointed sentences adapted from my hasty notes and vague memories, but some of it might prove useful, or at least entertaining. I'm writing it mostly because I enjoy writing and I need to practice more, and I'm cross-posting to my actual blog because I really should put some content there.

I will be at BETT 2012 and can't wait for it to come. Partly for "professional development," partly to see you Edugeekers again and partly to restock my desk with a bagful of freebie office supplies.
My freebie-fu was weak last year. With any luck it has since improved!

Neg rep because you dislike Reddit?
Or you're one of THOSE 4channers who think Reddit is the cancer of the internet?
If a picture is worth a thousand words, a reaction image if worth at least 500 emotions.
Just because something is from reddit/tumblr/4chan/wherever

I'm thinking of making one at work.
Think of it as CPD, if you like.
We have 10 old RM computers [F-series] just sitting there gathering dust.
We also have 4 switches sitting around, plus a lot of various cables.
Our head would probably let me do it... But, I can't think of a use for it...

I can't believe I just spent over half an hour changing my desktop wallpaper...
I had the wallpaper on a USB... It just wouldn't display properly.
Set it to "tiled", works fine.
"Center"... Still good.
The colour borks and it becomes worthless. This is what the wallpaper looks like, for those that are interested.
[NOTE - not the actual one that borked. This one borks
Ive had a lot of contact from people asking about installing System Centre Configuration Manager (SCCM) – having all sorts of issues with it. Normally – this install and config to the basics of doing a build and capture, through to the end game of it deploying your network clients for you!
Im not going to cover AD or DHCP – other than saying have 2 accounts setup ready to use, something like SCCMAdmin and SCCMClient. Make sure that you arent running SCCM on the same server as DHCP;
