N9K-C93108TC-FX Description
Cisco Nexus N9K-C93108TC-FX (Nexus 93108TC-FX) is a 1RU fixed leaf/ToR switch that brings 48 ports of 100M/1/10GBASE-T and six 40/100G QSFP28 uplinks to brownfield or greenfield data centers. It delivers 2.16 Tbps switching and over 1.2 Bpps forwarding, with 40 MB shared buffers for bursty east-west traffic. The platform supports VXLAN EVPN under NX-OS or policy-driven automation with Cisco ACI, offers MACsec on ≥10G ports, and provides dual OOB management (RJ-45 + SFP), hot-swappable N+1 fans/PSUs, and selectable airflow for consistent uptime and serviceability.

Key Features
Copper-friendly 10G leaf/ToR
Reuses CAT6/CAT6A runs for 100M/1/10G access while adding simple 40/100G spine uplinks—ideal for staged upgrades without recabling.
Line-rate security for regulated workloads
MACsec on ≥10G ports protects east-west and uplink traffic for multi-tenant, healthcare, and finance environments with minimal operational overhead.
Burst-tolerant fabrics for mixed apps
2.16 Tbps, 1.2+ Bpps, and 40 MB shared buffers smooth fan-in spikes from virtualization, backup windows, and storage traffic.
Day-0 to Day-N automation
POAP zero-touch bring-up, model-driven telemetry, and open APIs (NETCONF/REST/OpenConfig) fit cleanly with Ansible/Terraform pipelines.
Flexible fabric architectures
Operate as a VXLAN EVPN leaf under NX-OS or as an ACI leaf for intent-based segmentation—supporting both brownfield migrations and greenfield builds.
High availability & serviceability
vPC and ECMP for fast convergence, ISSU/SMU to shrink maintenance windows, plus hot-swap N+1 fans/PSUs and front/back airflow options.
Applications Scenarios
Enterprise & campus data centers
Top-of-rack 10G copper access with 40/100G uplinks for virtualization clusters, Windows/Linux estates, and appliance-heavy racks.
Hosting & MSP edge pods
Cost-efficient copper aggregation with per-port encryption and automation—perfect for multi-tenant racks, branch aggregation, and POPs.
Media, storage & backup domains
Shared buffers and telemetry help maintain low jitter during high-bitrate editing, NAS/iSCSI bursts, and nightly backup peaks.
