Re: [Xen-users] system suggestion

[Mario Minati <mario@xxxxxxxxx>]

Hi Andrew,

as allways it depends on your needs what is best for you.

If you are planning to run multiple VMMs (maybe 3 or 7 :-) on that 
machine I would suggest to take the 4x box, because you have more cpu 
power and each machine has its own cpu, on the other hand if your VMMs 
are going to be idle most of the time that it might be better to take 
the 2x one, because you have more peak cpu power. But anyhow 256MB is a 
bit less to run many VMMs on that machine with dom0 and 3 domU every 
gets 64MB, with 7 domU there will be only 32MB for each machine. And 
don't forget to think about energy consumtion, a 4 cpu machine like that 
can use *quite a bit* of electrical power, so if running 24/7 that will 
cost a lot, so it might be cheaper to by a newer machine. As said 
before, it depends on the use.
Regards,
Mario Minati
