Scenario: A multinational enterprise operating 10/40/100GbE data center fabrics must replace five legacy firewalls to support growing east-west traffic and encrypted workloads. Implementation: Deploy the SRX5400X-B3 chassis with enhanced midplane, SRX5K-RE-1800X4, SRX5K-SCB3, 2x HC PEM, HC fan tray, SRX5K-SPC-4-15-320 and dual SRX5K-MPC3-100G10G line cards on Junos 15.1X49-D10. Outcome: Delivers up to 200 Gb/s firewall throughput, reduces device count by 60%, cuts power/cooling costs by 40%, and ensures sub-millisecond latency for mission-critical applications.
Scenario: A Tier-1 service provider must support 100 GbE peering, advanced DDoS mitigation and encrypted carrier VPNs at the network edge. Implementation: Leverage the SRX5400X-B3 platform—enhanced midplane, SRX5K-RE-1800X4, SRX5K-SCB3, 2x HC PEM, HC fan tray, SRX5K-SPC-4-15-320 and SRX5K-MPC3-100G10G modules—running Junos 15.1X49-D10. Outcome: Provides up to 120 Gb/s of encrypted traffic, mitigates volumetric attacks up to 500 Gb/s, boosts service availability to 99.999%, and simplifies multi-site orchestration.
Scenario: A cloud hosting provider requires per-tenant segmentation and high-speed east-west inspection across hundreds of tenants. Implementation: Deploy SRX5400X-B3 chassis with enhanced midplane, SRX5K-RE-1800X4, SRX5K-SCB3, 2x HC PEM, HC fan tray, SRX5K-SPC-4-15-320 and SRX5K-MPC3-100G10G modules under Junos 15.1X49-D10. Outcome: Scales to 100 Gb/s inspection per tenant, hosts 200+ virtual firewalls, enforces granular policies, strengthens compliance posture and reduces lateral breach risk by 70%.
