The DP-9800-HS= stands out with Cisco’s custom ASICs, which optimize power efficiency and telemetry collection for AI-driven operations.
Addressing Critical User Concerns
Q: How does it integrate with existing Cisco ACI or SD-WAN fabrics?
The switch supports Cisco ACI integration as a spine/leaf node and aligns with SD-WAN overlays via VXLAN/EVPN. Its NX-OS APIs enable seamless policy orchestration.
Q: Can it replace older Nexus 9500 chassis switches?
Yes. The DP-9800-HS= offers comparable port density in a 1U form factor, reducing rack space and power costs. Migration tools like Cisco Network Assurance Engine (NAE) simplify transition workflows.
Q: What redundancy features are included?
Hot-swappable power supplies and fans, plus Hitless Upgrade (ISSU) for zero-downtime firmware updates.
Purchasing and Deployment Best Practices
For enterprises prioritizing scalability, itmall.sale offers the DP-9800-HS= with flexible licensing (perpetual/subscription) and pre-configuration services. Key considerations:
- Optical Compatibility: Use Cisco-certified QSFP28 transceivers (e.g., QSFP-100G-SR4-S) for optimal performance.
- Cooling Requirements: Ensure 25°C ambient temperature and front-to-back airflow for high-density deployments.
Why This Switch Redefines Data Center Economics
In a decade of deploying data center switches, few models match the DP-9800-HS=’s balance of density, efficiency, and automation. While competitors rely on merchant silicon, Cisco’s ASICs deliver tangible savings in power and latency—critical for AI and real-time analytics. For architects juggling CapEx and OpEx, this switch isn’t just a hardware upgrade; it’s a strategic lever to future-proof infrastructure against unpredictable traffic growth.
