rackmount question
hi all, ok, i'm trying to decide what exactly to put into my 1U rackmount case and thought i'd ask for some advice as i just can't make a decision. firstly, for reference purposes, this box is going to be to running several vmware virtual machines, so whatever i end up with needs to be able to cope with that. my main problem is trying to decide what processor to use. of course, this is partially down to what heatsink/fan i get. so far i've found two that should be suitable, the AKASA AK-350 1U Copper Cooler and the ALPHA PAL153U 1U cooler. now the Akasa apparently supports up to AthlonXP 2000+, Celeron 1.3GHz or P3 1.4GHz, but i've not been able to find any reviews to see how good it really is. I can't find any data on the processors supported by the Alpha, but i have found a review for it (http://www.anandtech.com/showdoc.html?i=1571p=6). In this review, however they tested by simulating the typical power usage of a 1GHz AMD Athlon MP (Palomino). since i can find AthlonXP's of 1700+ and 1800+ just either side of the cost of a Celeron 1.3GHz, i think it comes down to one of those chips. I imagine the AthlonXP's would be better than the Celeron, but would like confirmation on that from someone else. And if i do go for one of the Athlon's, is it really going to be cooled enough? I don't particularly want to lose a chip on this. So, anyone got any advice that could help me make a decision? Jody

To be honest if you don't need the CPU power (why would you?) I'd prefer
to get something that ran reliably. It's a major pain in the butt going

Re: rackmount question
Personally, unless you can find a really good heatsink *designed* for 1U high operation on AMD (this may involve searching http://www.overclockers.co.uk/ rather carefully) and a power supply which is meaty enough - I think you are looking at Intel Hardware.

We've tried several 1U boxes tha are supposed to run happily. On their own, they do, but some of them obviously like to radiate heat, as well as convect it. Stack 10 of them together, and watch them die within a few hours/day/weeks. So, if this is a just a one-off, and it's sitting in the middle of someone elses datacentre with all sorts of other kit, most hardware will be fine. If you can afford a bit of extra room around them, either put 2 machines in 3U for stacking, or make sure you've got a U of space sitting empty (also handy for storing a copy of the OS installer CD or whatever) Or possibly just go for a 2U case, they're normally much happier when filled with hot things, and much less fussy about that air gap. Or if you decide that you really could do with more disks, more PCI slots, more CPUs or anything else, give me a shout - we recently got some 4U machines, dual CPU, and 1.5 TB of disk (on 200GB HDs) and the case design was superb - didn't sound like a tornado taking off, yet managed to keep all that stuff unbelievably cool. the hatter

Oddly enough, that's almost exactly the reason I bought 16 of them.
Beware the 'not bad prices'.

As a general rule, I've found AMD chips need a great deal more cooling than Intel, which is why all my small-case boxes use Intel. Give serious consideration to two lower-speed processors rather than a single extra-grunty one. My last few colo boxes (general purpose servers) have been SMP, and I've found it well worth it. Roger

Unless you are putting this somewhere really expensive and well airconditioned (eg Telecity) then 1U boxes do not pay off in the (cost of box)V(cost of hosting) trade off. add in the less room for extra drives, more expensive PSU's, more heat etc and its a non-starter. Of course if you *are* putting it in Telecity, then you've probably got enough cash to just buy a Intel 1U boxen and a spare anyway. some places (eg mailbox) don't charge differently for a 1U or a 'desktop' sized machine anyway, so you aren't necessarily gaining anyting. -- Robin Szemeti

This hasn't been my experience - I paid about UKP200 more for a 1U case than I would have for a standard desktop, and Black Cat charge UKP15/U/month over the basic cost for anything over 1U. The air conditioning there is good, but not great; I haven't had any heat problems. Roger
