Works together

How the Dell PowerProtect DD Data Domain DD6800 connects to servers, storage and the network: 2 ways, with the parts and products on each path.

Fibre Channel SAN iSCSI and NVMe/TCP over Ethernet

Fibre Channel SAN

Serverwith an FC HBAFC switchtwo fabrics, A and BStorage arrayFC host ports

Match the speed: 16Gb and 32Gb FC HBAs, switches and array ports work together, and each generation also runs one or two speeds below its own (a 32Gb port runs at 16Gb and 8Gb).

Fibre Channel SAN: how it fits together

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.
