The following figure shows the internal drive configurations.
Figure 8. Internal drive configurations
In addition, the RD550 server models can be upgraded with 2x SD card internal slots, or 2x M.2 SSD
internal slots, or both. The SD card slots are connected to the Intel Platform Controller Hub (PCH) via USB;
therefore, they do not require a RAID controller. The M.2 SSD slots require a supported RAID controller (for
details, see Controllers for internal storage).
Note: M.2 SSD slots and 2x 2.5-inch rear drive bays are mutually exclusive, that is, either M.2 SSD slots or
2x 2.5-inch rear drive bays can be selected in the configuration, but not both.
The following table shows the internal storage options available for the RD550 server.
