7.3.7 Replacing a 2.5-inch HDD/SSD module
I PCIe SSDs SFF are mounted in the same frames as the 2.5-inch
HDD/SSD modules. Therefore, this section is also valid and applicable if
PCIe SSDs SFF are used.
V CAUTION!
●
Only remove an HDD/SSD module during operation if the drive is not
currently being accessed. Observe the indicators for the
corresponding HDD/SSD modules, see section "Indicators on the
hot-plug HDD/SSD module" on page 400.
●
An HDD/SSD module can be replaced while the system is in
operation.
RAID configuration with a RAID controller:

RAID configuration without a RAID controller:
Please follow the instruction of each software e.g. VSAN, Storage
Spaces, and Storage Spaces Direct, provided separately to use the
software RAID function of OS or Hypervisor.
