  • A10 Thunder 6430 ACOSEfficiency: Consolidated, Scalable Cloud Services in Compact 1U Hardware Appliances
  • Scalability: 150 Gbps Throughput, Large-scale Virtualization
  • Reliability: Maximum Uptime with Carrier Class Hardware

A10 Thunder 6430 and 6430S (with dedicated SSL hardware) are 64-bit 1U Application Delivery Controllers (ADCs) that provide Unified Application Service Gateway functionality by consolidating premium solution modules for intelligent Cloud Services in the most efficient form factor. Built on A10's scalable and flexible Advanced Core Operating System (ACOS) architecture, A10 Thunder Series platforms consolidate stand-alone solutions such as ADCs, Server Load Balancers, Carrier Grade NAT (CGN/CGNAT), IPv6 Migration, DNS Application Firewall, Web Application Firewall (WAF), SSL Intercept, Distributed Denial of Service (DDoS) protection, Application Access Management (AAM), and more, without license fees.

A10 Thunder 6430 models set a new industry efficiency standard delivering 5.3 million Layer 4 connections per second (CPS) and 150 Gbps of application throughput in 1U appliances. NITROX III SSL acceleration hardware delivers exceptional 2048-bit key performance with 130,000 SSL CPS (6430S). In addition, DDoS SYN Flood protection of 212 million SYN Cookies per second and concurrent session support of 256 million sessions bring overall performance to exceed any ADC vendor, per rack unit.

High-capacity and high-performance multi-tenancy with up to 1024 Application Delivery Partitions (ADPs) deliver large-scale virtualization and consolidation to enable more applications and services on a single platform, reducing deployment time and cost.
