Got great responses from several people, more than I can list.. thank you! The wisdom I took away was: Patching and downtime was mentioned in almost every reply - rightly so - Spend time planning for it. Have as much RAM as you can afford. Plan for having the server up for a long time since getting downtime will be a nightmare with lots of zones. It is certainly possible and several are hosting 30+ zones on M-series. If zones are OracleDB, RAM will be eaten up very quickly and you'll get a smaller consolidation ratio. ZFS will eat up RAM but doing zones without it is not as easy as with ZFS. -I personally love ZFS. Sometimes adding LUNS can be tricky and may require downtime for global zone. Use projects for resource control. Seems like a good mix of sparse and full root zones out there. Clustering it will just add to the maintenance and add a lot more management. Thanks again for all the excellent info. Jeff ________________________________ This message may contain confidential information.
