Works together
How the Dell PowerSwitch N3048EP-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.
