FAS2220 HA Version an 12 Disks. How Many Data Disks?



we plan to buy a FAS2220 in HA Version, but we dont know how many Disk in the System are Data Disks.

We plan to buy the Bundle with 12 x 900 GB Disks an set it up as a Active/passive configuration. The Documentation sais: In this configuration, the passive node has only a root volume.

How many Disk does he need for "only a root volume".?

And how many Data Disk are then available for the active node?
