Works together

How the cisco Nexus 9000 Nexus 9516 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.

iSCSI and NVMe/TCP over Ethernet: how it fits together

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.
