Observe these drive population guidelines for optimal performance:
•
When populating drives, add drives in the lowest numbered bays first.
•
Keep an empty drive blanking tray in any unused bays to ensure optimal airflow and cooling.
•
You can mix hard drives and solid state drives 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.

Do not configure 4K sector format and 512-byte sector format drives as part of the same RAID

Linux: RHEL 6.5, 6.6, 6.7, 7.0, 7.2; SLES 11 SP3, and SLES 12. ESXi/Vmware is not supported.
