  • Hi AJ768,

    it depends particularly on your network latency. As soon as the lacking logs are transferred to the passive node and then applied to its database, the passive node starts mounting the cluster ressources.

    In a scenario with a latency of 50 ms or less (comp. LAN-like), you can calculate a downtime of less than 3 minutes. This statement is NOT universally valid but a realistic value to orientate yourself. The actual downtime depends on your specific environment  and should be tested e.g. by conducting a guided handoff.

  • Agree with the above, normally well with 5 minutes, so you can set your RTO to 5 mins which Exch 2007 can easily meet. (CCR).
