I can see the benefit to not having swap in a server scenario, but to offer a counterpoint- it seems like IT likes to under allocate servers by something like 25%, so if you have a server with 256GB of RAM, by design it should never use more than 192GB. That’s a lot of RAM going to waste for the off-chance usage jumps above 75-80%.

I think I would rather have the server’s SSD be an Optane drive (or some other high-endurance flash memory) with a swap partition, and use some other means of monitoring and being alerted to high memory usage.

Except that there's nothing you can do if it starts swapping suddenly and you basically lose a server once it atarts swapping due to how slow it is

I’m not sure what this scenario is but it sounds like you’d be F’d with or without swap
