• When using SAS/SATA drives, the eight drives must be all SAS/SATA; no mixing with NVMe drives
is allowed.
• 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 SAS/SATA hard drives and SAS/SATA SSDs in the cage. 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 SAS/SATA hard drives or all SAS/SATA SSDs.
