Dell PowerSwitch S4112F-ON
The Dell PowerSwitch S4112F-ON is a compact half-width 1U open networking switch engineered for space-constrained edge locations, hyperconverged cluster interconnects, and dedicated storage fabrics. Providing twelve 10GbE SFP+ access ports and three 100GbE QSFP28 uplink ports, two S4112F switches can be mounted side-by-side in a single 1U rack slot to establish full network redundancy. Driven by Dell SmartFabric OS10 or open ONIE environments, it delivers wire-speed Layer 2/3 performance for small-to-medium clusters. Buyers should verify whether dual-mount 1U rack brackets are included.

Works together
How the Dell PowerSwitch S4112F-ON connects to servers, storage and the network: 3 ways, with the parts and products on each path.
iSCSI and NVMe/TCP over Ethernet
Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

Buying a used S4112F-ON: what to check
Confirm whether the single or dual-unit 1U mounting bracket is provided. Verify functionality of all 12 SFP+ and 3 QSFP28 ports, and inspect power supplies for quiet fan operation.
FAQ
Can two S4112F-ON switches mount in a single 1U space?
Yes, using the Dell dual-switch 1U tray bracket, two half-width S4112F switches mount side-by-side for redundant top-of-rack networking.
What are the 100GbE ports used for?
The three 100GbE QSFP28 ports provide high-bandwidth uplinks to spine switches or can connect cluster nodes via breakout cables.
