Multi-Tenant Exchange 2010 - Database distribution

We are starting to run a mutli-tenant exchange 2010 environment and currently running a CAS server and a separate HUB server. Both are virtulised servers using Citrix and running Windows server 2008 R2.

We have set the cas server up with separate drives for the databases and logs but for expansion planning, is there are recommended number of databases which should run on a drive before they are split over several drives? Each client is setup with their own database and would probably only have around 15 users, but are requesting quotas of 10 GB each.

Thanks Simon, that server has the client access as well as mailbox roles. Only the hub transport role was moved to a separate server.

For the monitoring, would it be better using the avg disk queue length counter or the current disk queue length counter? And which counters should be monitored for the I/O?
The two counters that you have listed are the main ones to watch.
If you look in the Toolbox in EMC you will see some preset perfmon counters.

Simon.
