X5WN8 - Dell PowerSwitch Z9100-ON 32-Port 100GbE Switch

Dell EMC PowerSwitch Z9100-ON 32x 100GbE QSFP28 + 2x SFP+ Layer 3 data center switch, 6.4Tbps switching capacity, OS9/OS10 support.

The Dell X5WN8 is the manufacturer part number for the Dell EMC PowerSwitch Z9100-ON, a compact 1U fixed-configuration Ethernet switch purpose-built for high-performance data center and computing environments. It offers a flexible port configuration supporting 32 ports of 100GbE, or alternative configurations of 64x50GbE, 32x40GbE, 128x25GbE, or 128x10GbE, plus two additional SFP+ ports for 10GbE/1GbE/100MbE connectivity. Built on a non-blocking switching architecture, it delivers line-rate Layer 2 and Layer 3 forwarding with low latency, making it suitable for use as a leaf or spine switch in Active Fabric and leaf-spine data center topologies. It ships with dual hot-swappable AC power supplies and runs Dell EMC Networking OS9 by default, with OS10 Enterprise compatibility for software-defined networking environments.
