What is the chipset od the NICs? Mellanox? Intel E810? Broadcom 2100g? Pensando? Do You use any kind offloads? I'm looking for something for my home lab 😉 btw 100g already for 2m users? That's crazy...
This is a load balancer. The NIC is of course doing a lot of the hard work and that's all ASICs. But then just a lot of CPU threads (~1 per Gbit/s) on a modern PCI bus.
Pretty amazing how powerful the most recent generations of hardware are!
Fortunately, it's a very simple HTTP load balancer for just a couple of in-house services. So observability is much easier than a generic router with a complicated mix of customers/services behind it, like at an ISP.
