  • In the past PowerFolder Server used a cluster policy that is defined in the external load balancer e.g. Nginx or Apache. PFS v15.0.100 contains a default cluster policy in that it is defined that the new users / folders are automatically registered to the server that contains the minimum number of folders so that the storage and the server capacity can be used and managed in smart way and the resources remained balanced.
