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?
If you want to make most of the space
You should be seperate 12 disk
you should be assign 10 disk controller A
you sohuld be assign 2 controller B
you can create aggr0 with 9 disk ---1 disk is spare--total 10
aggr0 with 9 disk-------7 data----2 parity--RaidDP
you can create aggr0 with 2 disk
aggr0-1 data-1 parity disk-- no spares Raid4---But not recomended (on root volume )
if you want right config
Assign 8 disk to controller A and create raiddp aggr with 7 disk and its also inculede ( 5data-2 parity ) and 1 spare total 8 disk
assign 4 disk controller B create raiddp aggr
aggr0- 3 disk (1data-2 parity)- 1 spare
