F5-BIG-LTM-R5800 Local Traffic Manager

F5-BIG-LTM-R5800: High-end LTM Solution for Large Enterprise Data Centers

The F5-BIG-LTM-R5800 is a high-performance model in the R5000 series, specifically designed to handle the most critical and performance-intensive application loads. Compared to the F5-BIG-LTM-R5600, it unlocks stronger hardware potential through software licensing, with the core advantage being an approximately 35% increase in overall performance and providing 50% more business processing cores (18 vs. 12 vCPU). This enables it to process more complex traffic with lower latency, making it ideal for industries such as large financial institutions, cloud services, and high-traffic online platforms.

Feature Highlights

80K TPS SSL Processing Capacity
Features powerful hardware SSL acceleration, capable of handling up to 80,000 SSL handshakes per second. This top-level performance allows it to serve as a core SSL offload engine for large enterprises or service providers, delivering smooth and secure processing of massive encrypted traffic to ensure the best user experience.

Flagship 18-core Business Processing
Up to 18 vCPU cores are dedicated to business processing (tenancy). More dedicated cores mean stronger processing power and lower latency when executing computationally intensive complex iRules traffic policies or handling large-scale concurrent requests, ensuring instant response for fine-grained strategy enforcement.

Enhanced Multi-tenant Virtualization
Supports up to 18 vCMP tenants, enabling higher density IT resource consolidation. This allows integration of more application delivery services on a single device or providing independent virtual ADC resources for different departments.

128GB Large Onboard Memory
Equipped with 128GB RAM, the R5800 stably supports up to 85 million concurrent connections and reserves ample space for running memory-intensive complex policies, effectively protecting your technology investment.

95Gbps Application Throughput
Delivers 95Gbps of app-level throughput—enough to drive the core of any mega data center or multi-cluster setup. Paired with native 100G/40G ports, it keeps your application-delivery heart pumping without bottlenecks.

LTM-R5800 vs LTM-R5600

• 35 % more raw muscle (SSL + throughput)
• 18 vs 12 business cores → 50 % extra CPU for heavy lifting

What are the benefits of 18 vCPU service cores?
• Spin up more or beefier virtual ADCs (vCMP) on the same box
• Run the gnarliest iRules without adding latency

Is LTM-R5800 suitable as a data center security gateway?
Yes.

• 80 K SSL TPS + 80 M SYN cookies = inspect and absorb massive encrypted floods
• Add AWF license for full-stack threat inspection and DDoS shielding
