I think you need to define your terms better. Most of us don't
know what you are refering to on VMS.
In order to load balance, multiple systems have to be offering the
same service at the same time. What application are you wanting
to load balance?
Having a cluster file system, goes a long way to making it easier to
offer the same service at the same time, and we will have a very
powerful aliasing facility as part of our release with cluster
file system.
I suggest you RTFM, to understand what the products can do now, and
read some of the presentations that discuss what is coming
(start in http://www-unix.zk3.dec.com/www/symp/symp.html )
The main benfit of cluster alias in the current release is
transparent access for clients to cluster services, regardless
of what node they run on. Most cluster services don't run on all
nodes at the same time. If the can/do, you can use DNS round robin
pointing to cluster services, and even use some load balancing if you
choose to use something like lbnamed
