Gopal,
We have a very close relationship with VOS and I have always found the Veritas side of VOS extremely competent and technically very sound. We are not currently running RAC (and there is a long story behind it) but if we run into any issues with LLT in the future, I have good faith that Veritas will resolve the issue for us.

	Amir,
	 
	With LLT, when you have an issue with performance/node evictions

you will be asked to reproduce the problem without LLT (i.e UDP) and you may not able to file bugs/enhancements with LLT. Contact me offline if you need more details on this .          

        RacDBAs... Do you guys have any details for wider audience?

	Hello,
	I have worked with LLT for over two years with DBE/AC 3.5 for 9i

RAC and found no issues what-so-ever with it (LLT). It is a very reliable protocol, proprietary though, but reliable. The LMX driver does the multiplexing and de-multiplexing for LLT, so if you are using multiple interconnects, your traffic will be load-balanced without you doing/configuring anything special. I have not really seen any clear statement from Oracle for de-supporting LLT in the future even though they have been emphasizing on using UDP, which is very typical of Oracle.
