The top ten reasons LPARS are great tools.
1. It's easy to create development environments. I can create an LPAR, set it on the dev network, and give the devs the root password. It's now their problem.
2. I can test maintenance levels, software upgrades, and scripts in my own admin sandbox against the same hardware that's running on production
3. Micropartioning allows me to allocate only the resources I need, and not affect the performance of the production system.
4. I can reboot my dev LPARS as often as I need to without affecting production
5. I save on rack space, cooling and power.
6. I save on maintenance costs
7. I save on network ports
8. VIO gives me great throughput between LPARS.
9. WLM lets me shift resources between LPARS automagically
10. Did I mention LPARS are really cool?
