Generations

Works together

How the cisco Nexus 6000 Nexus 6004X 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.

Hyperconverged cluster

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

FAQ

What was the significance of the 6004X in 40GbE adoption?

It provided one of the earliest high-density 96-port 40GbE non-blocking spine fabrics for enterprise private clouds.

Can ports on the 6004X break out to 10GbE?

Yes, every 40G QSFP+ port supports 4x 10GbE breakout DAC cables or optical transceivers.
