• SAS expander port 8 = drive numbers 21 to 24.
• SAS expander port 9 = drive numbers 25 to 28.
Common configuration examples:
NVMe drives
When any stacked 2 SFF drive cage is connected to the SAS expander, the drive numbering skips the second number. For
example, when a rear 2 SFF drive cage is connected to SAS expander port 9, then the drive numbers are 25 and 27.
When the front 24 SFF bays are populated, any installed rear 2 SFF drives are always 25 and 27.
Universal media bay
If a 2 SFF drive cage is connected to SAS expander port 3, then the drive numbers are 1 and 3.
