Works together
How the HPE P26264-B21 connects to servers, storage and the network: 3 ways, with the hardware 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.
