Steve,
You've narrowed it down quite nicely in your requirements. You mentioned
"either Oracle9i or 10g", and that is the key ambiguity, so to speak.
On 10g RAC, you have the choice of the following clustering options:
* Sun Cluster (Solaris 10 using SVM - a clustered volume mgr - and
QFS - a clustered file system)
* Veritas Storage Foundation for RAC (SFRAC) v4.x (clustered
volume mgr, clustered file filesystem)
* Oracle 10g RAC Cluster-Ready Services
On 9i RAC, you have the following clustering options:
* Sun Cluster (Solaris 8/9 using Veritas clustered volume mgr, no
CFS option at all)
* Veritas Storage Foundation for RAC (SFRAC) v4.1 (clustered
volume mgr, clustered file filesystem)
The Veritas solution is the only option common to both 9i and 10g, providing
a CFS (clustered file system) in both environments. Note also that using
Sun Cluster for Solaris 8 or 9 still requires Veritas clustered volume
manager, so when you're on 9i RAC, you've got no choice but to invite
Veritas to the party, even if using Sun Cluster.
Sun just introduced a clustered volume manager of its own (Solaris volume
mgr or SVM) and a clustered file system (QFS) with Solaris 10, whilst SFRAC
(formerly DBE/AC) has been out and about for several years, and is on its
third major release (i.e. 3.5, 4.0, 4.1). Similarly to Sun's SVM and QFS,
this is the "dot-oh" release of Oracle's clustering option.
Hope this helps...
