Sun Cluster 3.x is completely different to Sun Cluster 2.x. There are more
differences between the two versions than there are similarities.

The heartbeat stuff, as well as the need to have a terminal server is all
gone with Sun Cluster 3.x

"proprietary integration" ? Cluster on the high-end machines works in
exactly the same way as it does on the lower-end machines. There's nothing
special in the standard hardware or Solaris which acts differently.
There is one specific product which can have an impact on cluster configs,
being the WildCat interconnect boards, but that's an extra which is
just for better performance - it's neither required, built in, or used
in a standard HA cluster config.

Ditto Sun Cluster.
Obviously I'm a bit biased towards SC, and I've never actually run VCS
in anger, but I suspect either will do the job you're after without
Sun Cluster has the advantages of single-vendor support (same vendor
for OS, hardware and cluster) as well as tighter integration with the
OS. VCS has the advantages of slightly more flexibility (although
this is both an advantage and a disadvantage), cross-platform
administration (but ask yourself if that's really an advantage - it
depends on the environment).
Personally I'd recommend SC3, but like I said, I'm a little biased -
especially as I've installed 9x 2-node SC3 clusters in the past 2 weeks :)
