Citrix NetScaler MPX-21500 400 Gbit/s Rack-Mount

Keep critical applications responsive when traffic spikes and service levels matter most. Citrix NetScaler MPX-21500 is built for application acceleration, high availability, and network control in enterprise environments where latency, throughput, and uptime directly affect business operations. This rack-mountable appliance combines 400 Gbit/s throughput with 8 SFP+ slots, 2 RJ-45 ports, and Gigabit Ethernet connectivity to support demanding delivery paths across modern infrastructure. Manageable operation gives administrators the visibility and control needed to maintain performance without adding unnecessary complexity. For teams standardizing on physical appliances, the MPX-21500 offers the scale and interface mix required for high-volume application delivery while fitting cleanly into a 2U rack footprint. It is a practical choice when lower-capacity devices create bottlenecks, or when virtual-only approaches do not meet performance and control requirements. The result is a platform designed to sustain application access, reduce delivery friction, and support enterprise traffic patterns with confidence.
