4.7  2U 2.5” Front Mount Drive Bay Cable Guide  
The front drive bay of the 2U system can support up to three 2.5” x 8-drive bay modules providing support for the following system configurations: 8 
drives (R2208), 16 drives (R2208 + 8 Drive Accessory Kit), or 24 drives (R2224). Each of the three drive bay modules is identified by number as shown 
below. All eight drives of the standard 8 x 2.5” combo backplane can support SAS, SATA, and NVMe drive types. The backside (Cable connector side) 
of the standard combo backplane will include two 4-port 8643 Mini-SAS HD data connectors (Ports 0 – 3 & Ports 4 – 7) for SAS/SATA support, and 
eight PCIe OCuLink connectors for NVMe support (one connector for each PCIe NVMe SFF drive). Each OCuLink connector is labeled with a Drive ID (0 
– 7) which corresponds to a matching drive interface connector on the front side (drive interface side) of the backplane.  
Note: The dual port SAS backplane option includes four 4-port 8643 mini-SAS HD connectors and does not have support for PCIe NVMe drives.
