adding 400GBSSD to 200GBSSD raid5 pool on Unity300
a customer with a Unity300
FAST VP Pool:
Raid5 4+1 - 200GB SSD
Raid5 4+1 1.2TB SAS
1 hotspare 200GB SSD
1 hotspare 1.2TB SAS
Customer wanted to expand the SSD tier, but received 5x 400GB disks in stead of 200.
What happens if he adds them to the FastVP pool ?

a new private raidgroup gets created with the 400GB disks
It will work but not best practice - see the Unity BPP white paper
keep in mind that you will also need a 400GB spare
