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

		HDD1	HDD2	HDD3	331695
HDD4	HDD5	HDD6	HDD7	HDD8

Figure 3-7 Drive Numbering, Large Form Factor

HDD1 HDD2 HDD3 HDD4

331696

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.
