Additional Features
Recommended Hardware
NGINX Plus was designed and optimized for use on generic server hardware. For an edge server capable of serving 3 to 6 Gbps of live traffic and 20,000 to 50,000 requests per second, we commonly recommend the following:
  • 2 modern x86_64 CPUs with 4 to 8 cores per CPU
  • 16 to 32 GB RAM
  • 6 x 250-GB SSD drives (if required for cache and storage)
  • 10-GbE Intel networking card
