About the Dell PowerSwitch Z9664F-ON
The Dell EMC PowerSwitch Z9664F-ON is Dell's flagship spine-layer switch, offering 64 ports of 400GbE QSFP-DD in a compact 2U form factor, delivering 51.2Tbps of total switching capacity. Built on Broadcom's Tomahawk 4 ASIC, it is designed as the spine or super-spine layer of large enterprise and service provider spine-leaf fabrics, interconnecting dozens of 25GbE or 100GbE leaf switches in a non-blocking architecture that supports both traditional IP/BGP routing and modern VXLAN/EVPN overlays.
The Z9664F-ON's 400GbE ports can be broken out to 4x 100GbE or 8x 50GbE per port using appropriate breakout cables, providing extraordinary flexibility to serve as a spine switch in existing 100GbE fabrics while future-proofing for 400GbE leaf-to-spine migration. It runs SmartFabric OS10 with the full automation and programmability feature set, consistent with all other PowerSwitch Z-series products.
The switch is purpose-built for AI/ML GPU cluster networking, where it serves as the spine interconnect between InfiniBand-to-Ethernet gateways and 100GbE leaf switches feeding GPU servers. It is also commonly deployed as the data center interconnect (DCI) spine in multi-data-center enterprise environments, carrying VXLAN tunnels between geographically distributed leaf-spine fabrics over 400GbE dark fiber or DWDM wavelengths.
Ideal for
- Spine layer in large enterprise spine-leaf data center fabric
- AI/ML GPU cluster 400GbE spine interconnect
- Data center interconnect (DCI) between multiple sites
- Super-spine in three-tier (leaf/spine/super-spine) fabrics
- Service provider colocation core switching
- High-frequency trading fabric core for ultra-low latency east-west traffic
