• You can mix drives of different types and different capacities in one system, but not in one RAID array.
The following order is recommended when installing the drives:
– Drive type priority: SAS SSD, SATA SSD, SAS HDD, SATA HDD
– Drive capacity priority: the lowest capacity first
• The drives in a single RAID array must be the same type, same size, and with the same capacity.
Before installing a hot-swap drive:
1. If there is a drive filler installed, remove it and keep it in a safe place.

2. Touch the static-protective package that contains the new drive to any unpainted surface on the outside
of the server. Then, take the new drive out of the package.
