Switches... 24 or 48 ports?
As above, if you were speccing switches which would you go for? Basically we're getting the HP 2610 series, originally thought 48s as we have now with another brand but was advised to get 24s instead.
What it kinda comes down to I guess would be...
- noise... 24 ports are silent but 48s have a fan, will soon see how much noisier
- cable management... easier with 24 ports
- switch throughput, per 1GB link into it?
Any other ideas as I'm still a bit torn which to go for...

I suppose 48 port also gives you a single point of failure
2 x 24 ports require 2 plugs!

48 ports were possible. Rack space is at a premium round here.

we've got a few 48s where rackspace is tight. Otherwise we have the 24s!
If you've got the space you may aswell go with the smaller. As already been said, you've spreading the eggs over a few baskets is always good :P

We're having some redevelopment work occuring during the summer (well.. building work is starting next week), and will be having an entire floor newly wired, so I have been pricing and speccing up what switches we'll want.
I do tend to find recommendations for 24port switches only, which I guess for the reasons of noise and minimizing inconvenience if one breaks (you only lose 24 ports instead of 48), and of course to load balance the switches. We will just go for 48port switches all round as there is still inconvenience whether you lose 24ports or 48, and surely the more switches you have, the more heat it will generate (defeating the aim of noise reduction as you'll need more cooling)?
Factor in the cost too, whereby a 48port switch is generally a tad more expensive than 2x 24port (although I noticed this being the other way around with HP switches), and given HP is whom we are going for, the cheaper cost of 1x48 also made the decision easier. Rack space wont be a problem for us as we'll be buying a new rack which will naturally provide ample capacity for current and distant future expansion.
I'm not aware of any technical reasons why one should favour a 24port over a 48 (load balancing probably wont make any real noticeable difference here), but I guess you need to see what switches you will go for, and decide upon the price, space you have got and capacity required.

After last night I've decided... 24s all the way!
Had a loopback issue with the current crappy cabling, diagnosing the fault was a bloody nightmare! First had to check the stack (Allied Telesyn switches blehh) then try to narrow down the ports.
Could barely get near the connections as the cables are in such a mess, after uplugging about 96 cables (yeah I know the 50% rule but didn't apply very well when you can't see what's being unplugged :P ) finally found the duff one
Can't wait until it's just a few fibers, much easier to diagnose that way!
