this is the complete list of  VMware HA Advanced Options that you should use configuring a VMware Cluster :

• das.failuredetectiontime – Amount of milliseconds, timeout time for isolation response action(with a default of 15000 milliseconds).
• das.isolationaddress[x] – IP adres the ESX hosts uses for it’s heartbeat, where [x] = 1‐10. It will use the default gateway by default.
• das.usedefaultisolationaddress – Value can be true or false and needs to be set in case the default gateway, which is the default isolation address shouldn’t be used for this purpose.
• das.poweroffonisolation – Values are False or True, this is for setting the isolation response. Default a VM will be powered off.
• das.vmMemoryMinMB – Higher values will reserve more space for failovers.
• das.vmCpuMinMHz - Higher values will reserve more space for failovers.
• das.defaultfailoverhost - Value is a hostname, this host will be the primary failover host.
• das.failuredetectioninterval – Changes the heartbeat interval among HA hosts. By default, this occurs every second (1000 milliseconds).
• das.allowVmotionNetworks – Allows a NIC that is used for VMotion networks to be considered for VMware HA usage. This permits a host to have only one NIC configured for management and VMotion combined.
• das.allowNetwork[x] – Enables the use of port group names to control the networks used for VMware HA, where [x] = 0 – ?. You can set the value to be ʺService Console 2ʺ or ʺManagement Networkʺ to use (only) the networks associated with those port group names in the networking configuration.
• das.isolationShutdownTimeout – Shutdown time out for the isolation response “Shutdown VM”, default is 300 seconds. In other words, if a VM isn’t shutdown clean when isolation response occured it’s being powered off after 300 seconds.
• das.bypassNetCompatCheck – Disable the “compatible network” check for HA that was introduced with Update 2. Default value is “false”, setting it to “true” disables the check.
• das.ignoreRedundantNetWarning – Remove the error icon/message from your vCenter when you don’t have a redundant Service Console. Default valie is “false”, setting it to “true” will disable the warning.
• das.maxvmrestartcount – The maximum amount of retries to start a VM, where <x> 1..(reasonable number), 0 for no restarts, -1 for indefinite. The default is 5.

Virtual Machine Monitoring HA advanced options

• das.failureInterval = The polling interval for failures. Default value is 30.
• das.maxFailureWindows = Minimum amount of seconds between failure. Default value is 3600 seconds, if VM fails within 3600 seconds VM HA doesn’t restart the machine.
• das.maxFailures = Maximum amount of VM failures, if the amount is reached VM HA doesn’t restart the machine automatically. Default value is 3.
• das.minUptime = The minimum uptime in seconds before VM HA starts polling. The default value is 120 seconds.

Hope this help
