The 1U version of the DL380 Gen9, same processor generation and management stack in half the rack space. Eight 2.5 inch bays typical. Good choice when rack units matter more than drive capacity, and a common pick for compute nodes in a Proxmox cluster.
Across 96 listings tracked in the last three days, the median total cost in USD including shipping is $319, and the lowest is $130. RackSniper flags a listing once it falls at or below 70 percent of the trailing 30 day median, which for this product means roughly $223 or less. Condition and configuration vary widely on used enterprise hardware, so treat the median as a reference point rather than a target.
