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 ("Drive numbering" on page 15).
• All drives grouped into the same drive array must meet the following criteria:
o They must be either all SAS or all SATA.
o They must be either all hard drives or all solid state drives.
o Drives should be the same capacity to provide the greatest storage space efficiency when drives
are grouped together into the same drive array.
