Re: Storage choice for Oracle database on VMware

Hello Dimitre,
what is the problem with direct I/O? You should never run an Oracle database through page cache anyway :)

I would go with tweaked XFS (e.g. "nobarrier" as this information is usually not passed through correctly with VMDKs on VMFS, etc.) if it is just one single instance in this VM.
