No it's not cluster aware, however it does know about shared disks so if 
you tell
it that it's running on shared disks, and tell it one system is a master 
and the others
are readonly slaves it will work and do pretty much what you would expect.
Search for 'readonly' in the manual for the settings you need.

The gotcha's are:
         1) If bandwidth to the shared disks is limited performance will be 
limited by that.
         2) Your reliability is not doubled as it is with two system 
sitting next to each other
         with their own disks as most failures are likely to affect both 
systems equally.
         3) I presume the nt clustering will to some extent fail over 
automatically, this feature
         is not supported in any automatic sense, but could be achieved 
manually probably.
