A while back I wrote down all the HA advanced options. With ESX 3.5 Update 2 VMware added a couple extra advanced options, this is the complete list:

• 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] = 0‐9. 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.

The new ones:

• 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.
