Drive Installation Guidelines; Installing A Non-Hot-Plug Drive - HP hpe proliant dl20 gen9 User Manual

Drive installation guidelines

When adding drives to the server, observe the following general guidelines:
•
The system automatically sets all device numbers.
•
Populate drive bays, based on the drive numbering sequence. Start from the drive bay with the
lowest device number
•
All drives grouped into the same drive array must meet the following criteria:
They must be either all SAS or all SATA.
o
They must be either all hard drives or all solid state drives.
o
For the most efficient use of drive space, the drives must have approximately the same capacity.
o
Each configuration utility treats every physical drive in an array as if it has the same capacity as
the smallest drive in the array. Any excess capacity of a particular drive cannot be used in the
array and so is unavailable for data storage.
