Cisco Nexus N3K-C3464C 64x100G DC Spine Switch Layer3

Brand:

Cisco Nexus N3K-C3464C is a 64x100G QSFP28 high-density data center switch designed for modern spine-leaf architectures. It enables ultra-low latency, scalable cloud connectivity, and VXLAN-based virtualization, supporting enterprise, HPC, and AI-driven workloads in large-scale environments.

OVERVIEW

  • The Cisco Nexus N3K-C3464C is an ultra-high-density 100 Gigabit Ethernet data center switch built for cloud-scale, enterprise, and service provider environments. Featuring 64 × 100G QSFP28 ports in a compact form factor, this switch delivers massive throughput, ultra-low latency, and high port scalability for modern spine-leaf architectures.
  • Designed for next-generation data centers in Singapore, the N3K-C3464C supports high-performance computing (HPC), AI/ML workloads, large-scale virtualization, and hyperscale cloud deployments. With Cisco NX-OS software, it offers advanced Layer 2 and Layer 3 features, automation capabilities, strong security controls, and operational efficiency.
  • Its high-density 100G design reduces rack space requirements while maximizing bandwidth, making it ideal for spine, aggregation, or data center interconnect (DCI) roles.
