We're getting ready to start our install of Clearpass and one of the server requirements for the CP-VA-5k is 1TB of space for each of the 4 servers we will be running. Is that really true? I really need to come up with 1TB for each server? That seems like a lot. 

I don't see anything about the network IO that these boxes will need. Is there an estimate of the max they will need? 

and now for CP-500, it is also 1Tb... it is crazy !

alagoutte, typically users skip the VM and get the hardware appliance for the 25K to avoid having to manage the dedicated  resources on a VM.

for 25K, yes... but for a CP-500 (and Guest)...

Nobody here is going to guarantee you that it will work with less than the recommended specs so you're on your own for that.

What can be said is that it works just fine when you deploy it with less disk space. Aruba just can't guarantee that it will remain enough. It will depend on your use and your cleanup settings.
