The Cisco Nexus N6K-C6001-64P is a high-performance data center switch from Cisco Systems designed to deliver ultra-low latency, high port density, and scalable networking for modern enterprise and cloud environments. Built in a compact 1RU form factor, this switch provides 48 fixed 1/10 Gigabit Ethernet SFP+ ports along with 4 high-speed 40 Gigabit Ethernet QSFP+ uplinks, enabling flexible connectivity for servers, storage, and aggregation layers.
Engineered for line-rate Layer 2 and Layer 3 switching, the Nexus N6K-C6001-64P offers a 1.28 Tbps switching capacity and 960 Mpps forwarding rate, ensuring reliable performance for high-bandwidth workloads. With sub-microsecond latency, it is well suited for latency-sensitive applications such as high-frequency trading (HFT), big data analytics, and large-scale virtualized data centers.
This switch runs on Cisco NX-OS, delivering a comprehensive feature set that includes VXLAN overlay networking, Cisco FabricPath, and Fibre Channel over Ethernet (FCoE) support. These capabilities enable organizations to build scalable unified fabrics that consolidate LAN and SAN traffic while maintaining high efficiency and flexibility.
The 40GbE QSFP+ uplink ports can also be configured for 4×10GbE breakout, providing additional server connectivity and deployment flexibility. With redundant hot-swappable power supplies and fan trays, the Nexus 6001 ensures continuous operation and high availability for mission-critical data center infrastructures.
Designed for modern spine-leaf architectures and cloud networks, the Cisco Nexus N6K-C6001-64P provides a powerful foundation for organizations looking to deploy high-performance, scalable, and energy-efficient data center switching solutions.

FAQs:
Q1. Can the 40G QSFP+ ports be used for 10G connectivity?
Yes. By using a QSFP+ to 4x SFP+ breakout cable, each of the four 40G ports can be split into four 10G ports, increasing the total 10G port count to 64.
Q2. Does this switch support Cisco ACI?
No. The Nexus 6001 is a standalone NX-OS switch. For Cisco ACI (Application Centric Infrastructure) environments, you would typically look at the Nexus 9000 Series.
Q3. What is the benefit of the FCoE support on this model?
FCoE allows you to use the 10G SFP+ ports to carry storage traffic to a Fibre Channel SAN, reducing the number of Network Interface Cards (NICs) and cables required in your servers.
Q4. Is the airflow direction fixed?
No. The switch supports both port-side intake and port-side exhaust.However, you must ensure that the power supplies and fan trays installed match the desired airflow direction (indicated by color-coded handles).
Q5. Does it support stacking like the Catalyst series?
The Nexus 6001 does not use physical stacking cables. Instead, it uses Virtual Port Channel (vPC) technology to allow two switches to appear as a single logical entity to downstream devices for redundancy and load balancing.
