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?

We use this hardware for our remote offices and this is the configuration that we use to maximize space.
Node 1 - One aggregate of 9 disks (RAID-DP) with one spare. This will give you approximately 5TB of usable space on the aggregate (7 data disks, 2 parity disks). If space it really a concern you _could_ go RAID-4 here but I wouldn't recommend it for production data.
Node 2 - One aggregate of 2 disks (RAID-4) with no spares. You will get alerts about there being no spares available but you can stop those by setting 'options raid.min.spare_count' to '0'
