Hot-plug SAS and SATA hard drive options
When adding hard drives to the server, observe the following general guidelines:
• The system automatically sets all device numbers.
• If only one hard drive is used, install it in the bay with the lowest device number ("SAS and SATA
device numbers" on page 15).
• Hard drives must be SFF types.
• Drives should be the same capacity to provide the greatest storage space efficiency when drives are
grouped together into the same drive array.
