How best to allocate storage when creating a VMware DB server

I am relatively new to Linux but have been working with AIX for over 10 years. We are getting ready to convert our current oracle database servers from the AIX platform to RHEL7 servers on VMWare. I would appreciate any advice on how best to allocate storage to these machines. I plan on using LVM to maintain the disks/filesystems but am unsure on how to initially assign the SAN storage to ensure the best performance possible.

In our current AIX environment we have separate disks/volume groups for the different types of data being stored. i.e. database files in a different volume group than O/S data, etc. On the SAN side the disks are on different storage devices as well so we can avoid any type of bottlenecks.

When creating a VM would I take this same approach?

Any advice on this would be appreciated.
