raid - vsphere 5 - what is the best way to partition local disks?

WE have a Dell R815 with 6x900GB SAS disks and a perc h700 controller.




We want to use it as a dedicated bare metal vsphere server (stand alone).



We have no idea what the best way to partition the beast.



Currently its one big RAID 5 array, with 3 virtual disks:
0=1.8TB
1=1.8TB
2=500GB



We could just run with this, and install vsphere 5 on disk 2, and I guess we can use both the other partitions for VMS (i.e. create 2 storage pools). However, 500GB is probably a waste for just installing vsphere. Also, we guess that to get best performance, we would want different VMS running on differnetn disks via differnt channels in the controller?




Does anyone have any suggestsions for the best disk/raid layout is?
