This really seems to be a topic you want to discuss with your SAS onsite tech support/contractor. Before they can provide a viable solution, they need to know almost every aspects of your institution in this regard. Your budget (which is everything), your hardware resource configurations, dev/test/prod setups, your data source (SAS table, RDBMS, hadoop etc), your user populations, your data usage, the proportion of DI/ETL jobs, the usage of EM (could be overwhelming), how many scheduled jobs, ad-hoc jobs ect, and how they distributed in 24 hours, the expected data usage growth in a few years, IT/Security/Regulatory restrictions and many many others. In the institution (20k+ employees and 500+ SAS users, financial sector) I work for, it took several month and dozens of meetings before they can come up a plan.
