LSF Standard and the LSF Suites are two distinct product offerings with different licensing entitlements. So yes, you only have access to the packages you have an entitlement for, and that is what you are entitled to deploy.
The Suites use ansible and rpm's for deployment. At present the rpm's are not relocatable, but you could select the NFS install option and symlink from old to new.
It's been a long running debate on whether "system software" should be installed locally, or installed on an NFS share....and there are very strong views held by both camps.
The Suites packaging is trying to address both.....hopefully!By default, it will install RPM's locally onto each node.
The 10.2.0.9 installer has an additional option to do a NFS install - so it will put everything into an NFS share; then you can just use lsf.conf/init.d/system.d to point at the share as you currently do.
Yes for the suite, service packs will be rpm's
