Product Review

The Cisco N9K-X9636Q-R offers a high-performance solution with 36 40 GbE QSFP ports and a throughput capability of 1.4 Tbps, making it suitable for environments demanding high bandwidth and efficient data handling. However, to achieve its maximum bandwidth, the necessity for four fabric modules, with an additional one or two for N+1 or N+2 redundancy, may present a scalability concern for some network infrastructures. Additionally, its compatibility with both N9K-SUP-B and N9K-SUP-B+ supervisor modules, alongside a substantial packet buffer of 12 GB and support for up to 750,000 IPv4 routes, underscores its capacity to handle extensive data flows and maintain high levels of network performance.


The Cisco N9K-X9636Q-R is a high-performance line card designed for the Cisco Nexus 9500 platform, offering advanced features for scalable, high-density, and high-speed data center networks. This line card provides 36 ports of 40 GbE QSFP, catering to the demands of extensive data throughput and connectivity. It is engineered to support a performance level of up to 1.4 Tbps, ensuring efficient data handling and transmission across the network. To achieve maximum bandwidth and ensure system reliability, the line card requires the installation of four fabric modules. For enhanced redundancy and network resilience, configurations of five (N+1) or six (N+2) fabric modules are recommended. This flexibility allows network administrators to tailor the system's redundancy level to meet specific network requirements and maintain uninterrupted service. The Cisco N9K-X9636Q-R is powered by an 8-core 2.4 GHz x64 processor, accompanied by 16 GB of DDR3 memory. This combination provides the computational power and memory capacity required for managing complex network operations and handling large volumes of data. The line card also features a substantial packet buffer size of 12 GB, facilitating smooth data flow and reducing packet loss during peak traffic periods. Networking capabilities include support for up to 750,000 IPv4 routes, 750,000 MAC address entries, and 250,000 multicast routes. This extensive capacity makes the line card suitable for large-scale networks with high demand for IP routing and multicast data distribution. Additionally, it can accommodate up to 4096 VLANs, allowing for extensive network segmentation and improved security.
  • Links in a port channel and ECMP routes support up to 256, enabling load balancing and redundancy across multiple links.
  • Support for up to 1000 port channels enhances network flexibility and scalability.
  • Active Cisco SPAN sessions can number up to 32, aiding in network monitoring and troubleshooting.
Weighing 11.48 lbs, the N9K-X9636Q-R is designed for easy integration into existing rack setups. Its typical power consumption is 329 W, with a maximum of 456 W, indicating its efficiency in energy use relative to its performance output. The line card boasts an impressive MTBH (Mean Time Between Failures) of 273,370 hours, highlighting its reliability and longevity in demanding data center environments. Compliance with RoHS-6 standards ensures that the line card meets global environmental and safety regulations. It also adheres to a wide array of EMC immunity and emissions standards, including EN55024, CISPR24, EN300386, and 47CFR Part 15 (CFR 47) Class A, among others.
