To chime in on this: I don't believe you would need to purchase
multiple copies of CF for virtualized servers, only one per *physical*
server, with up to 2 max CPU's.
Since the license for CF is for 1-2 CPU's, running it on an unlimited
number of VM's residing on a single physical server (dual C

Jochem,
The PDF example is great. I'm not against CF Enterprise whatsoever, it's the

Depends on the purpose. Let me counter by complementing you
Contrary to some of the other opinions in this thread, I think that getting
windows in multiple VMs is a better way to go than getting CF on multiple
JVMs, and I have a fair amount of experience to back that up.

That limit is per-instance. Each instan
I have been through several set ups recently, the latest is 2 physical
servers with a cisco pix load balancer with no sticky sessions. we
then run 2 jrun instances for the production app on each box. Provides
great stability.
One limitation on the number of jrun instances on windows is the

Good catch, I would have missed that.

you have obtained the appropriate license for each physical server (and
all their processors) you can add as many CF instances as you want.
Each of them belonging to one big cluster or several smaller clusters.
