Six 2.5-inch SATA drives, four 2.5-inch NVMe drives and rear SAS/SATA drive assembly
Notes:
• When the SAS/SATA backplanes are connected to PCIe connectors on the system board, only SATA
drives are supported. No SAS drives are supported.
• The cable routing illustration is based on the scenario that the rear hot-swap drive cage is installed.
Depending on the model, the rear hot-swap drive cage might not be available on your server.
