Hi list,
I have couple questions related to Exadata but first a little bit of background story:
I am considering different solutions for database consolidation as well as
increasing high availability of single systems in one step.
At present our production systems (OLTP & DWH) are running more or less as
isolated 'islands'.
Since the Data-Center is getting bigger & bigger so our DC as well
operational bill too.
Many systems don't really need dedicated HW to run on, so two or more of
them can be consolidated to run on e.g. one 2-node HA cluster with
sufficient CPU and IO resources to satisfy total needs of all databases
running on such high available 'consolidated platform'.
Oracle VM is not an option.
Lets put licensing topic aside for now.
So, now back to original topic ;-)
One of the options I am considering is Oracle Exadata. I had a first (and short) workshop with people from Oracle which was more let's say high-level presentation of Exadata. The figures presenting 'power' of Exadata are impressive. That's one side of picture.
Topics which are still open for me are:
- Patching/Upgrade of Exadata Storage Servers, Firmware, InfiBand switches
as well as other HW components
- how oft this need to be done?
- patching/upgrade in rolling fashion possible or not?
- Real life operational experience with Exadata
- I would be very grateful for any insights and experiences from list members with Exadata experience i.e. faced bugs, problems & issues
- Oracle sales presented a Turkcell as one which used Exadata as consolidation platform ... if anyone on the list is working for them and would be kind enough to share experience I would be very grateful.
Many thanks in advance to anyone kind enough to tackle above topics.
cheers,
goran
