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
