SUMMARY: virtualization effort on Solaris 10

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
