Drive Population Guidelines
The server has two different drive backplane options:
•
The small form factor (SFF) drives version can hold up to eight 2.5-inch hard drives or solid state
drives.
•
The large form factor (LFF) drives version can hold up to four 3.5-inch hard drives.
The drive-bay numbering is shown in
Figure 3-6
.

Drive Numbering, LFF Drives, Four-Drive Version
Observe these drive population guidelines for optimum performance:
•
When populating drives, add drives to the lowest-numbered bays first.
•
Keep an empty drive blanking tray in any unused bays to ensure proper airflow.
•
You can mix hard drives and SSDs in the same server (the LFF version of the server does not support
SSDs). However, you cannot configure a logical volume (virtual drive) that contains a mix of hard
drives and SSDs. That is, when you create a logical volume, it must contain all hard drives or all
SSDs.
