N9K-C9332C Description
Cisco Nexus N9K-C9332C (Nexus 9332C) is a compact 1RU fixed 100G spine switch delivering 32 QSFP28 40/100-GbE ports plus two 1/10-GbE SFP+ utility ports for high-density leaf-spine fabrics. With 6.4 Tbps switching capacity and 4.4 bpps forwarding, it provides predictable, non-blocking performance. The platform simplifies operations with no port breakout support, offers wire-rate MACsec on the last eight QSFP28 ports to secure core links, and runs either Cisco NX-OS or Cisco ACI to fit automation-driven data center designs.

Key Features
32 × QSFP28 40/100G in 1RU enables dense, power-efficient spines for VXLAN EVPN or ACI fabrics with minimal rack footprint.
Wire-rate MACsec on the last eight QSFP28 ports secures leaf-to-spine or inter-POD links without throughput penalties.
6.4 Tbps, 4.4 bpps and 40 MB shared buffers keep queues shallow under fan-in bursts common to east-west traffic.
No breakout, hot-swappable PSUs/fans, and dual OOB management shorten deployment time and streamline field service.
Run NX-OS or ACI; integrate model-driven telemetry and open APIs to standardize Day-0 to Day-N workflows.
Typical 296 W (AC) helps reduce TCO across multi-chassis spines while maintaining headroom for feature growth.
Application Scenarios
Acts as a 100G spine aggregating large fleets of 25/100G leafs with predictable latency and simple scaling.
Secures inter-POD and border connections with MACsec while supporting multi-tenant segmentation at the core.
Handles bursty trading flows, HPC checkpoints, and render traffic; hardware telemetry accelerates troubleshooting.

My team’s risk-averse procurement approved Layer23. That should tell you everything.
Good product, good price, good service. Wish the lead time was a bit shorter, but product quality made up for it.
Vendor lock-in usually concerns me. With Layer23 I’m happy to be locked in.
You delivered the goods. I respect that.
We expect the best, and you provided it. Thank you.
