15. Is Exadata a more available infrastructure than the HPE competitive configuration?
A properly designed Oracle RAC cluster on HPE gear provides the same availability as an
Exadata appliance
16. Can we leverage HP's new persistent memory to offload, redo, undo?
Certainly there is potential here and it could really improve performance for update
intensive workloads. I suspect that Oracle will throw a lot of FUD at it
17. Can we approach Debra directly in order to get support to handle exadata competition
in one of our existing account
The best way to formally engage Debra and our team is by opening a request in SFDC
18. Does the whitepaper for SDX contain the tuning recommendations for NUMA
configuration?
Yes it does, The Best Practice whitepaper documents testing done using NUMA tuning
within Oracle
