For OpenAFS the hard coded server limit for UBIK services is 20 and the maximum number of vlservers that can be specified in a CellServDB is 8. The maximum number of servers that any particular cell can successfully operate might be as low as 3 depending on how busy the servers are, how frequently write transactions occur, and the network path characteristics. A minimum of 3 non-clone servers are required to permit write transactions to succeed when one of the servers is shutdown or becomes unreachable. For AuriStorFS the maximum UBIK server limit and maximum number of vlservers that can be specified in a cell configuration is 80. There are no performance restrictions that limit their use.
