more RAM + faster disk -> slower box?!

I'm looking for a job... :-)

Now you've posted that to the list, I confidently predict it will die 
horrendously within 48 hours. Well, it will as soon as I break into the 
building. :-)

My main experience has been with hardware RAID, not vinum. RAID controllers 
are a bit like security guards and club bouncers - they don't like to be 
confused, and if you try and take the mickey, they'll bite back. I've had all 
sorts of problems in the past. Hopefully, come the Spring, I'll be building 
up my new server monster which will probably involve quite a large (10x160Gb 
ATA) vinum array. No doubt, I'll end up blowing up £5k's worth of drives and 
myself in the process. Around then, expect lots of worried posts on this list 
from me asking whether the CPUs are supposed to smoke, and why the 'really 
cheap RAM I bought from Bowlers smells funny'.

Oh, I'm scared! My MicorVAX could have them any day. My IPX sits in the 
corner of the living room in fear of it...
