Drive Population Guidelines
The server has two different drive backplane options:
• The Small Form Factor drives version can hold up to eight 2.5-inch hard drives or solid state drives.
• The Large Form Factor drives version can hold up to four 3.5-inch hard drives.
The drive-bay numbering is shown in Figure 3-6.
Figure 3-6 Drive Numbering, Small Form Factor
Figure 3-7 Drive Numbering, Large Form Factor
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 air flow.
• 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.
