2008 server revision/labs

Anymore than four and it crys a little bit but I've been able to deal with it.. The main thing letting it down seems to be the RAM, but my poor little lappy can't take anymore than 4GB! :(
 
Yep, RAM is definitely the biggest factor in running a virtual lab I've found. I have 4GB and can run 4 VMs with 512Mb each on my Win 7 system without any issues, but 5+ starts to slow things down.
 
Interesting, I have a suspicion that disk is also at play here, 5 machines and 4GB is 666 meg per machine (inc host) which isn't TOO bad, but 6 machines all on one disk, especially on a lappy.

I guess having more mem allows the disk to be used less.
 
I have a lab setup within virtualbox, 2 servers, 1 v-router and 1 xp client :D

works really well actually, although its stretching my 2.5gb ram!
 
As mentioned previously, there's not really much to ESXi and although it's good to put on your CV, its no where near the complexity of ESX
Actually the two products, apart from ESX having a service console, are identical in almost everyway.

So from a technical point of view, not having a built in GUI, is more complex to a lot of people ;)
 
Passed 70-640 W2K8 AD this morning with a score of 950. Only another 5 exams to go now!

Well done!



Any body have any idea of roughly how many VMs a HP ML115 will be able to run with 8GB of mem? None of the VMs will be production, and just used for labs stuff, if it could run 8 or more without running dog slow that would be ideal. (I'll look at getting a better disk than the one that comes with it!)

If your running ESXi, then v4 can technically do upto 20vcpu's per logical CPU, and v4u1 can do upto 25.
Basically, your gonna be limited by your RAM rarther than the CPU.
8x 1Gb RAM VMs should be ok, the system will just memory baloon for the VMs that need more/less at various times, keeping everything running nicely. :).

Yeah I knew RAM will be the main bottleneck, but I was more worried about disk capability. I'm a bit skeptical as to how fast it will run with 4+ OS's running from a disk, sure that means just getting two disks, but I'm worried about the disk sub-system as a whole, and I've not heard good things about the ML115's controller.
 
The OS's, when up and running, wont actually use all that much disk I/O. Unless your running a lot of file system intensive apps.

Its the initial boot that'll slow it down the most tbh.
 
A standalone ESXi box is a massive waste of time. Nobody is going to take you seriously if you claim you have VMWare experience because you've installed it on a desktop - as someone who has worked for years in the field and gained qualifications/valid exeprience, it's actually midly offensive.

Anyway, my laptop (C2D with 4gb RAM and a 7200rpm HDD) runs a few VMs in workstation just fine - enough for revision purposes anyway, it's not like you've got any load on them
 
I thought 70-640 had been phased out in favour of 83-640 in the UK? i.e. not just multiple choice questions but lab work too?

D'oh, sorry, you're right. It was 83-640 I took, although I'm actually in Australia. 70-640 is only available in non-english languages.

How did you find the new exam format and the lab exercises? I hear there have been a lot of reported bugs with the new exam.

No bugs at all, as far as I could tell. The labs were 2 full W2K8 virtuals running somewhere out on the web. Once connected, it's exactly the same as navigating around your own virtuals. I got 10 tasks per lab, and they included DNS, Schema, Sites and Services, GPOs, NTDSUtil, and general Users and Computers stuff. Speed wise they were pretty good, the only issue I found was with typing - typing too quick caused letters to input several times. Took me a few attempts doing cmd line stuff because of this!

The only thing that I would have liked would have been a score breakdown at the end like you used to get. As it is, I have no idea which questions/tasks I got wrong as I thought I knew all of them and was on for 1000.
