    Admission control in Vsphere 5.5

    btboMT Lurker

      I've read all about HA admission control on yellow-bricks and lots of other sites but still have trouble pinning a number on how many guests we can add to our clusters without violating HA.

      We are using Host failures cluster tolerates as the admission control policy which calculates failover based on slot size.

      As an example here's an image of a cluster with two hosts and no cpu or memory reservations.

      Available slots is 198 but I can't believe we could add that many vm's to this cluster. What is the best way to plan how many "average" guests we can add?

      198 at the obviously not feasible 32mhz and 2300mb?
