Hi David
Not sure to be honest... We failed over yesterday twice (I think I was causing
that particular issue). I have not tried pulling the plug (so to speak on the
VMware NIC), generally I have powered off a Node. Although, I have requested a
'test' button from Emilio via the Forum to force a flip of the Active Host.
In practice what happens is the standby node come alive on the Virtual
interface very quickly jus a few seconds, the default is 5, so I guess that
sounds right.
Any Citrix clients immediately drop their connections/applications (as the
can't see the Citrix farm any more) on port 443 - normal service comes back on
in under one minute. I have my Citrix sessions set to 60 seconds, so generally
people just auto-reconnect and carry on from where they left off. I also use
PNAgent to populate the user desktops with Citrix icons - the other day this
took at least a couple of minutes to respond to pings.
My web base CRM drops users too, then just need to close IE and log back on.
Speed is not an issue for my SMTP feed. I have asked for more details on the
FarmGuardian, as I would definitely use this to improve my detection, and
subsequent recovery times.
I have an Isolated network set up in VMware, so I can do a little more test
over the next few days and let you know.

Nick,
How fast do your clusters fail over? If you disconnect one of the nics
in vmware?
I'll try turning enable promiscuous mode back off
