Each HDD/SSD module can accommodate an SAS/SATA HDD or SSD with a

backplane wirelessly. This allows HDD/SSD modules to be plugged in or pulled
out easily.
Six SATA HDDs/SSDs can be controlled by the onboard SATA controller. To
control SAS HDDs/SSDs, an additional SAS / RAID controller must be installed.
Hybrid configurations of SAS HDDs, SATA HDDs, SAS SSDs and SATA SSDs
within the same logical drive (RAID array) are not supported.
If the server node has the corresponding RAID configuration, HDD/SSD
modules can also be replaced during operation.
