Correct, however Red Hat also tested up to 60 for FreeIPA. Certainly I know there is a deployment in the world that has scaled up past 1000 servers. Generally once you get past say 8 servers, you need to think about your replication topology and how the data will flow. The largest sites I know tend to go to maximum 8 write-accepting servers, and then replicate to N hubs and replicas that are read only past that for the best performance and reliability. > > Regards, > > > Paul M.

It sounds to be a hardcoded limitation defined to avoid overloaded servers and network. Shouldn't it be depending on the MMR topology, i.e. rather on the total number of replication agreements within the whole scenario? Or does "20 masters" indeed mean that the limitation of the MMR topology is the number of 380 replication agreements as shown in the "fully connected mesh" scenario (https://access.redhat.com/documentation/en-us/red_hat_directory_server/10/html/deployment_guide/designing_the_replication_process-common_replication_scenarios) with 20 masters and 20x19 replication agreements? >> Is there someone who possibly has experience with scenarios of more than 20 master servers? >> Thanks, >> Eugen >> _______________________________________________ >> 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx >> To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx >> Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ >> List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines >> List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx > > _______________________________________________ > 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx > Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx — Sincerely, William Brown Senior Software Engineer, 389 Directory Server SUSE Labs, Australia _______________________________________________ 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx
