In a typical clustered configuration, you have the storage connected
to multiple servers. Each server would then export a given LUN to a guest
domain on that server. You would then configure the guest domains on different
servers into a cluster. So, no, it doesn't limit your cluster size.

If you are talking about multiple guest domains WITHIN a server, then
to get access to data on those LUNs you would use other techniques such as
the Cluster Filesystem (pxfs). It doesn't limit the size of the cluster
per-se.

The maximum number of cluster nodes with Solaris Cluster remains
unchanged with this announcement. For SPARC, i believe it is currently 16,
but there were plans to qualify 32 nodes, if not already so.
