Dell PowerSwitch S5224F-ON
The Dell PowerSwitch S5224F-ON is a compact 1U open networking switch providing twenty-four 25GbE SFP28 server ports and four 100GbE QSFP28 uplinks for medium-sized data center racks, high-speed storage clusters, and software-defined networking. Powered by the Broadcom Trident 3-X4 silicon, it delivers 2.0 Tbps of line-rate switching capacity with low latency. Supporting ONIE, users can deploy Dell SmartFabric OS10 or open NOS environments such as SONiC. On the refurbished market, it is popular for cost-effective 25GbE transitions in smaller server pods. Buyers should confirm matching fan and power supply airflow orientations.

Works together
How the Dell PowerSwitch S5224F-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.
