LUNS for CIFS server

Hi

I am about to create first CIFS server and already created Storage Pool with about 2 TB of space. Now it is the time to create some LUNS for this CIFS server (it will be only one server).

I will create thin LUNS with deduplication and my question would be is it better to create few bigger LUNS for example 4 LUNS of 500 GB or for example 10 LUNS of 200 GB of space.

Not sure whether this will make any difference in terms of performance but would like to find out what would be the best practice
