I have done a 7 pass erase on a half rack V2 which took about 8 hours.
1 hour for the flash disks and 7 for the cell disks. I am unsure why resource
usage is a concern when you are decommissioning the kit.(you obviously do not
have any apps running on the kit)
Please note that any grid disks which are inactive/offline will not be scrubbed

We got to returned our leased old exadata boxes and need to destroy all data

Oracle says they don't want us to erase more than 2 disks at the same time.
Their recommendation would take us forever to get out of the box.
Has anyone got any experience with this? Especially wiping disks in parallel.
The guy from Oracle says it consumes a LOT of CPU.
I think it should be IO bound. Why does he say that?
