Works together
How the Fujitsu PRIMERGY RX4770 M4 connects to servers, storage and the network: 4 ways, with the parts and products on each path.
Fibre Channel SAN
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).
Switches
Brocade G-Series G610 1U
Cisco MDS 9132T 1U
Dell Connectrix DS-6620B 1U rack
Dell PowerSwitch S4148U-ON 1U switch

Lenovo ThinkSystem TS4300 Tape Library 3U rack
Optics

57-1000333-01 Brocade 32G FC SFP+ SWL
57-1000487-01 Brocade 16G FC SFP+ SWL
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.

Direct-attached SAS
12Gb SAS uses Mini-SAS HD (SFF-8644) connectors; older 6Gb gear uses Mini-SAS (SFF-8088). Adapter cables exist, but the link runs at the slower speed.

File storage (NFS and SMB)
Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.
