  35. Using Maximum Values for More than One Configuration Options with Clusters:
    If any one of the configuration options in a cluster is used at its maximum limit value, the ESXihost and vCenter Server with default configuration should be able to withstand the values.If more than one configuration options (such as number of virtual machines, number of LUNs, and number ofVDS ports) are used at their maximum limit, some of the processes running on the host might run out ofmemory. This might cause the host to keep disconnecting from the vCenter Server. In such a case, you need toincrease the memory pool for these host processes so that the host can withstand the workload you areplanning. You need to increase your memory pool size in correlation to the number of configuration optionsyou are using at the maximum value.
