Clustering within VMware6.5

I am undecided on whether doing Windows clustering (WSFC) used to be MSCS inside VMWare or not.  I need a way to monitor my application and windows services particularly.  I am not aware of a way that VMWare can monitor windows services and restarted them.  If I do windows clustering inside VMware, I am concerned about the complexity and losing some of the VMware HA features.  Any thoughts or advice on the subject is greatly appreciated.

Thank you for the link.  Do you know if this has been implement successfully and any concerns or issues with doing it?  If High Availability required, are there any other options beside Microsoft clustering watching the application level?  Thanks again

Hi Andrew,

The basic current requirements are to provide High Availability to the application level and windows services which I understand not really supported by the HA tools from VMware.  The old days of straight MSCS provided these needs and I am looking to see what can be done without making the design complex or loosing any of the VMware HA features if MS clustering is used within the VM.  Thanks

Please define :- High Availability ? 1 days downtime, 10 minutes, 2 minutes or 30 seconds?

All VMware HA does, is restart a VM on another host, if that host should fail due an uncontrolled shutdown, e.g. host crash.

This can take 1-2 minutes for the service/VM to start.

Microsoft Failover Clustering can still be used with VMware. This protects your application.

You could use VMware FT, but this keeps a VM replicated with the Primary VM, should the Primary VM fail, the Secondary VM takes over. - zero downtime.

BUT, it the OS crashes or Service crashes, this will not help you. (as this is replicated to the Secondary)
