F5 BIG-IP i5800 vs. VPR-LTM C2400-AC: Which Application Delivery Controller Reigns Supreme?
When architecting modern application infrastructures, F5’s BIG-IP Local Traffic Manager (LTM) stands as a cornerstone. But selecting between the i5800 (physical appliance) and VPR-LTM C2400-AC (virtual edition) demands a nuanced comparison. Here’s a granular breakdown to inform your decision.
Metric | F5 BIG-IP i5800 | F5 BIG-IP VPR-LTM C2400-AC |
---|---|---|
Max Throughput | 2.5 Gbps | Scalable up to 10 Gbps (VM limits) |
Concurrent Connections | 200,000 | Unlimited (hypervisor-dependent) |
SSL Transactions/sec | 20,000 | 100,000+ (via vCPU scaling) |
Latency | ~1 ms (optimized for WAN) | ~500 μs (hypervisor-dependent) |
RAM | 8 GB | 4-32 GB (configurable in VM) |
Storage | 480 GB SSD | N/A (runs on hypervisor storage) |
Why it matters: The i5800 excels for edge deployments with fixed bandwidth needs, while the VPR-C2400-AC scales dynamically for cloud-native apps.
Feature | i5800 | VPR-LTM C2400-AC |
---|---|---|
Security | SSL Offload, DDoS Mitigation | Advanced WAF, Bot Defense |
Traffic Management | Layer 7 Routing, GTM Integration | GSLB, Automated Traffic Steering |
Analytics | Real-Time Metrics | AI-Driven Predictive Analytics |
DevOps Integration | iControl REST API | Full CI/CD Pipeline Support |
Compliance | PCI-DSS, HIPAA | FedRAMP, GDPR |
Key differentiator: The VPR-C2400-AC’s container-native support accelerates microservices deployments.
i5800: 1 RU rack-mount, 2 expansion slots, passive cooling.
VPR-C2400-AC: 100% software-defined, deployable on x86 servers or public clouds.
Why choose VPR? Zero hardware constraints for hybrid environments (on-premises + AWS/Azure).
i5800: GUI-driven with limited automation; ideal for static environments.
VPR-C2400-AC: Deep CLI scripting, Ansible/Terraform integration, and F5 Automation Toolchain for CI/CD.
Real-world win: Enterprises adopt the VPR-C2400-AC for its zero-downtime upgrades via blue-green deployments.
i5800: ~30k-
50k (CAPEX-heavy upfront).
VPR-C2400-AC: 15k-
30k/year (OPEX model with licensing flexibility).
ROI insight: The VPR-C2400-AC pays for itself in 18-24 months through scalability and reduced hardware maintenance.
Neither model uses batteries, but the VPR-C2400-AC’s hypervisor-native efficiency slashes data center power costs by 40% vs. physical appliances.
Compatibility | i5800 | VPR-LTM C2400-AC |
---|---|---|
Cloud Platforms | AWS, Azure | AWS, Azure, GCP, VMware Cloud |
Virtualization | VMware, Hyper-V | VMware, Hyper-V, KVM, Bare Metal |
Security Partners | Palo Alto, Check Point | Palo Alto, Check Point, Zscaler |
Edge case: The VPR-C2400-AC natively integrates with Kubernetes Ingress Controllers for containerized apps.
Both run TMOS, F5’s legendary OS, but the VPR-C2400-AC adds:
iApps LX Templates for rapid app deployment.
NGINX App Protect for web application firewalling.
SD-WAN Overlay for hybrid architectures.
Buy the i5800 if: You prioritize simplicity for branch offices or small data centers with stable workloads.
Choose the VPR-C2400-AC if: You’re future-proofing for cloud-native apps, multi-cloud sprawl, or dynamic scaling needs.
One last question: Does your environment demand adaptive security and frictionless scalability? If yes, the VPR-C2400-AC’s pay-as-you-grow model delivers unmatched agility.
