Secure Boot and digitally signed firmware further ensure the integrity of the switch operating environment.

Zoning and Access Control

Intelligent zoning mechanisms such as Smart Zoning and hardware-enforced zoning enable precise control over device communication. Zoning not only improves performance but also limits potential attack surfaces by restricting device visibility.

Secure Fabric Services

The MDS 9396S supports Cisco TrustSec for storage networks, enabling secure device identity and policy enforcement. Integration with AAA (Authentication, Authorization, and Accounting) services ensures that only authorized personnel can configure or access the switch.

Energy Efficiency and Data Center Optimization

The port-side intake airflow design of the DS-C9396S-48IK9 enhances thermal efficiency by aligning with front-to-back cooling strategies in modern data centers. The switch also features power-optimized components and energy-efficient transceivers that reduce operational costs without compromising performance.

Compact Form Factor for Rack Efficiency

The 2U rack-mount design saves valuable rack space, allowing more equipment per rack unit. This compact footprint is ideal for space-constrained environments where high-density deployment is crucial.

Reduced Power Consumption

By leveraging low-power ASICs and intelligent power management, the MDS 9396S minimizes energy consumption while maintaining top-tier performance. This contributes to lower total cost of ownership and supports green IT initiatives.
