Works together

How the Dell PowerSwitch Z9664F-ON connects to servers, storage and the network: 4 ways, with the parts and products on each path.

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

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.

File storage (NFS and SMB): how it fits together

Hyperconverged cluster

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

Hyperconverged cluster: how it fits together

GPU cluster fabric

InfiniBand adapters and switches must match the generation: HDR is 200Gb, NDR is 400Gb. VPI adapters such as ConnectX-6 and ConnectX-7 can run either InfiniBand or Ethernet.

Buying a used PowerSwitch Z9664F-ON: what to check

Examine quad 2400W power supply units and specialized high-amperage power cords, test 64 QSFP-DD optical cages, check high-volume fan tray operation, and verify NOS licensing.

FAQ

What switching silicon powers the Z9664F-ON?

It is powered by 51.2 Tbps next-generation switching silicon capable of processing billions of packets per second.
