16-bay 2.5" drive cage for PowerEdge R720 and R820
This cage adds sixteen 2.5-inch drive bays to compatible Dell PowerEdge R720 and R820 servers. It uses part number 0N2R9K and connects through the server's existing backplane infrastructure. The unit suits administrators expanding local storage capacity in these rackmount platforms.
Sustained operation in multi-drive arrays
The cage holds up to sixteen drives simultaneously, so airflow and backplane throughput become the limiting factors during continuous I/O. Dell's original thermal design for the R720 and R820 accounts for fully populated cages, keeping drive temperatures within specification under steady workloads. No active cooling is integrated into the cage itself.
Direct replacement install with alignment checks
Installation follows the standard chassis slide-in procedure for the R720 and R820; the cage seats into the mid-plane connectors without cabling. Misaligned connector pins or debris in the slot are the most common causes of drive detection failures after fitting. Verifying full seating before powering on avoids repeated reseats.

Questions about this item
How much heat or noise does the 16-bay cage add when the PowerEdge R720 runs continuously?
The cage itself has no fans or active components; thermal load and noise come from the drives you install and the server's own cooling system.
What must already be present in the chassis for this 8 x 2.5" cage to connect and power 16 drives?
A compatible Dell PowerEdge R720 or R820 with the correct backplane connectors and drive-bay mounting points for part 0N2R9K.
Will this 16-bay cage work alongside the original drive cages already fitted in an R720 or R820?
It replaces or occupies the same bay area as the factory cage, so you cannot run both the original and this expansion cage simultaneously.
