I have HP P2000 + XenServer solution working. What I'm thinking about is how to create LUNs for 20 virtual machines. Separate LUN for every VM ? It gives me ability to backup the specific virtual machine, however 20 vm = 20 shared storages in XenCenter and moreover I'm afraid of manageability of these LUNs or am I wrong ? Or I can have one bigger LUN for 20 VMs. What is the better option?

I also think you need to ask yourself a few questions which will help you decide how many LUNs you want to create and how many VMs to deploy to each:
For example, if I have a heavily used database server that has a long data retention policy I will create a LUN for just the database data and perhaps put the operating system VM in a bucket LUN that holds other non-intrusive/not heavily used VMs.
Make sense?
