N9K-C9364C Description
N9K-C9364C is a Cisco Nexus 9364C 2RU fixed-port data center switch for Nexus 9000 spine fabrics with 64 fixed 40/100G QSFP28 ports and 2 fixed 1/10G SFP+ ports.
The main procurement difference from N9K-C9332C is density: N9K-C9364C doubles the QSFP28 port count, uses a 2RU chassis, and provides 12.84 Tbps bandwidth, while N9K-C9332C is the smaller 32-port 1RU model. Cisco also states that breakout cables are not supported on this 9364C platform, so the port plan should stay aligned to native 40G or 100G QSFP28 links and documented adapter use.
For quote preparation, verify Cisco ACI Spine or NX-OS mode, supported optics from Cisco transceiver tables, 1200W AC or 930W DC power selection, port-side intake or exhaust airflow, and rack-mount accessories before the hardware and optics are ordered together.

Product Performance
Key Features
N9K-C9364C is built around 64 fixed 40/100G QSFP28 ports, so it fits data center fabrics that need high 100G spine density without moving to a modular chassis.
The 2RU form factor matters when comparing this SKU with N9K-C9332C, because the 9364C trades more rack height for double the QSFP28 port count and higher switching bandwidth.
Cisco documents the switch for Cisco ACI Spine or NX-OS mode, so the purchase should match the intended fabric operating model and software plan.
Cisco states that breakout cables are not supported on this model, which makes the optics and cable plan different from newer platforms that support more flexible breakout designs.
The last 16 QSFP28 ports are marked as MACsec-capable in Cisco documentation, which should be considered when mapping encrypted leaf-to-spine or secure fabric links.
The platform has Cisco-listed port-side intake and port-side exhaust options for power and cooling, and the selected power supply type should match the rack power design.
Application Scenarios
Deploy N9K-C9364C when the fabric requires a Cisco Nexus ACI Spine switch with 64 fixed 40/100G QSFP28 ports. It is a stronger fit than N9K-C9332C when the spine layer needs more high-speed ports in fewer switch nodes.
Use this SKU for NX-OS environments that need fixed QSFP28 aggregation across servers, leaf switches, or service blocks. The 2 x 1/10G SFP+ ports can support auxiliary Ethernet connectivity while the primary data plane remains QSFP28-based.
Select this model when the cabling design is based on native 40G or 100G QSFP28 links rather than breakout cables. The order should confirm supported optics, QSA adapter needs, airflow direction, and power source type before installation planning.

- In a N9K-C9364C vs N9K-C9332C comparison, the primary difference is port density: N9K-C9364C provides 64 QSFP28 ports in 2RU, while N9K-C9332C provides 32 QSFP28 ports in 1RU.
- The N9K-C9364C difference from N9K-C9332C also includes switching bandwidth and memory, with 12.84 Tbps and 32 GB on N9K-C9364C versus 6.4 Tbps and 16 GB on N9K-C9332C.
- For buyers deciding which model to choose, N9K-C9364C is the comparison point when the design needs maximum 40/100G QSFP28 count in this fixed-spine pair.
Selection Guide
1. Select N9K-C9364C for 64-port QSFP28 spine density
Choose N9K-C9364C when the bill of materials requires 64 fixed 40/100G QSFP28 ports in a Cisco Nexus fixed spine switch.
2. Move to N9K-C9332C for a smaller 1RU spine
Use N9K-C9332C only when 32 QSFP28 ports are enough and the rack plan prioritizes a 1RU switch over the higher port count of N9K-C9364C.
3. Avoid designs that depend on breakout cables
Keep N9K-C9364C out of port plans that require breakout cables, because Cisco documents breakout cables as unsupported on this model.
4. Confirm optics, power, and airflow as one BOM review
Verify Cisco-supported optics, QSA adapter requirements, 1200W AC or 930W DC power selection, airflow direction, and rack accessories before finalizing the quote.
