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.
