Works together

How the Dell PowerSwitch Z9332F-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.

Hyperconverged cluster

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

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.

Check compatibility with Dell

Before you buy, confirm the exact configuration against the vendor's own lists: firmware levels, operating systems, adapters and optics that Dell has tested with the Dell PowerSwitch Z9332F-ON.

Equivalent models from other brands

Buying a used PowerSwitch Z9332F-ON: what to check

Confirm 400GbE QSFP-DD optical module recognition, test 2000W high-voltage power supplies on 208V+ circuits, inspect fan modules for thermal compliance, and verify OS10 licenses.

FAQ

What breakout configurations does the Z9332F-ON support?

Each 400GbE QSFP-DD port can break out into 4x 100GbE or 2x 200GbE links, yielding up to 128x 100GbE ports in 1U.

Does the Z9332F-ON support Enterprise SONiC?

Yes, Dell Enterprise SONiC distribution is fully validated on Z9332F-ON hardware.
