Exchange 2010 Memory usage

Hi there,
My exchange 2010 is consuming memory like crazy.  On install I had offered 8GB RAM to this Virtual machine, made about 5 databases, increased to 12, saw in the task manager that it has consumed 10.5 and stays at 10.5, then increased to 14, looked in task manager performance it has consumed to 13GB.  Seeing all this behaviour of exchange 2010 I am now on 20GB of RAM and if I look into the tast maanger performance it is through out consumed 17.9.  
This behaviour is making me think if some configuration change needs to be made on exchange 2010 to let me know how much it needs?
Need help plz

Exchange needs lots of memory and will consume whatever is available generally.
Are ALL Roles installed on the one server?
If so then 20GB is not a bad starting point for memory.

Have you used the prepare for Exchange calculator to determine what you actually NEED in terms of hardware?

Exchange will take (nearly) all memory available in standard configuration. This is by design and it will give memory back if needed by the system.

I can just can give you a link explaining Exchange 2007 Memory Management - for 2010 the essentials should be the same:

No Action required, Server or Exchange is working as per the design. Make sure to set the page file size Actual + 10 MB. Which means 20GB + 10 MB.

20 GB is enough. How is disk I/O? Goto EMC>Toolbox and run the performance tool....gather the information and check it.
