The best practice is to have only one storage pool in a VDC, unless you have more
l
than one storage use case at the site. In a site with a single storage pool, each DAE
in each rack must have the same number of disks.
Upgrade rules for systems with either four nodes/DAEs 8 TB or four nodes/DAEs 12
TB (upgrade will include mixed disk capacities in the rack):
The minimum number of disks in a DAE is 10.
l
Disk Upgrade Kits are available in 5 or 10 disk increments.
l
No mixing of disk capacities in a DAE.
l
Each four node/DAE must have the same disk capacity and number of disks in
l
increments of 5 (10, 15, 20, and so on, up to 60) with NO empty slots between
disks in DAE. Example: nodes 1-4, 30, 6TB disks in each DAE, nodes 5-7, 20 12TB
disks in each DAE.
All empty drive slots must be filled with a disk filler.
