This section includes the following information:
• Drive Population Guidelines, page 3-12
• Drive Replacement Procedure, page 3-12
Drive Population Guidelines
The server has two different drive backplane options:
• The Small Form Factor version can hold up to eight 2.5-inch drives.
• The Large Form Factor version can hold up to four 3.5-inch drives.
The drive-bay numbering is shown in Figure 3-5 and Figure 3-6.
Figure 3-5 Drive Numbering, Small Form Factor
Figure 3-6 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. 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.
Drive Replacement Procedure
To replace or install a hot-pluggable hard drive, follow these steps:
Tip You do not have to shut down or power off the server to replace hard drives or solid state drives (SSDs)
because they are hot-pluggable.
Step 1 Remove the drive that you are replacing or remove a blank drive tray from the bay:
a. Press the release button on the face of the drive tray. See Figure 3-7.
b. Grasp and open the ejector lever and then pull the drive tray out of the slot.
