Hey folks,
I have a set up of 5 nodes on one box and 5 nodes on another box, now my question is, how do you calculate that you need 5, theres no documentation for set up etc but im want to know why 5, why not 3, why not 2?? I suppose im looking for is the factors you have to take into consideration when deciding how many nodes you have and on how many machines etc

I know its quite an open ended question i.e will depend on hardware, no of users etc etc but just looking for the criteria that you use to calculate this

I have seen on the wiki last week a formula for calculating this but cant find the damn page anymore.

cheers for any help,
LL
