Works together

How the cisco Nexus 9000 Nexus 9504 connects to servers, storage and the network: 3 ways, with the parts and products on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

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.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.

FAQ

What is unique about the backplane design of the Nexus 9500 series?

It uses a direct-orthogonal fabric where line cards connect directly to rear fabric modules via high-speed pins, eliminating a traditional midplane bottleneck.

Does the Nexus 9504 support Cisco ACI?

Yes, with ACI-compatible line cards and supervisors, it serves as an ACI modular spine chassis.
