SolutionI'd suggest to create 3 VDISKS. You get better performance, because of 3 separate IO channels. Even 400GB is rather big disk and I'd suggest to make sw stripeset. But it depends on type of storage, on XP it's more meaningful than on EVA, and on application. If it's an archive, then single 400GB VDISK is suitable.

Re: Vdisk Size Good to have few or more
You should also create 3 VG with each one filesystem in it.
It is easier to handle in the future if you should add extra disk space

Re: Vdisk Size Good to have few or more
If you loose one vdisk with all data, you need to restore all 900 GB. So create a vdisk for every data type to be stored, so backups and restore can be managed in a more efficient way.
