I’m wondering what is the maximum amount of sites/subscriptions that a plesk install can allow? Is it dependent on diskspace?
The version we have installed is psa-11.0.9-rhel6.build110120608.16.x86_64



  1. Think, it mostly depend on OS/file system settings and settings of such services like apache, nginx, mysql and postfix. I have seen several articles in parallels knowledge base which are describing tweaks for increasing maximum amount of domains. For example:

    Obliviously there is should be a limit caused by internal software design. I know that there are plesks with ~1000 of domains and ~5000 of mailboxes. By the way, I know that there is Parallels Plesk Automation, it’s a product for middle hosters and it’s allows divide hosting services by different servers, which also allow to increase amounts of domains.

    May be it’s prefer to ask on, may be there are guys which are faced with big stand-alone plesk servers?

  2. There is a limit on the number of domains you can have, depending on your license. On one of my cloud servers, the limit is 30 because that’s what my license allows.
