Hard drive options
The server provides non-hot plug capability through an embedded SATA controller. To obtain SAS or
SATA hot-plug capability, install an optional controller and hot-plug cable option kit.
Hard drive guidelines
When adding hard drives to the server, observe the following general guidelines:
• The system automatically sets all drive numbers.
• If only one hard drive is used, install it in the bay with the lowest drive number.
• Drives must be the same capacity to provide the greatest storage space efficiency when drives are
grouped together into the same drive array.
Optional storage controllers provide support for hot-plug capability and drive LEDs. Controller options
are:
• The embedded controller supports non-hot-plug SATA hard drives. Drive LEDs are not supported.
• Optional SATA controllers support hot-plug SATA hard drives and drive LEDs.
• Optional SAS controllers support hot-plug SAS or SATA hard drives and drive LEDs.
NOTE: ACU does not support mixing SAS and SATA drives in the same logical volume.
Removing a hard drive blank
Remove the component as indicated.
CAUTION: To prevent improper cooling and thermal damage, do not operate the server unless all bays
are populated with either a component or a blank.
Removing hard drives
To remove the component:
1. Back up all data on the hard drive.
2. Power down the server (on page 16).
3. Remove the hard drive.
