Question How many customer sites per server?

[Paul123]

Server operating system version

Debian 11

Plesk version and microupdate number

18.0.58

I was wondering how many customers can typically be hosted on one server.

Currently, I have around 750 customers on a WordPress Multisite installation that I would like to migrate to a Plesk server, with each having their own WordPress installation.

Would this setup fit on a server with the following specs:

CPU - Ryzen 5 3600
RAM - 64GB ECC
Disk - 2 x 1.92 TB in RAID1 (that's enough)

Each customer only has a few visitors a day.

Email is currently on a separate mailserver, but I could consider migrating that as well. Do you guys have any real-world experiences or best practices to share?

Will probably work. Maybe a bit more RAM could be a good idea, but this depends on what the websites are doing.
