Advice on allocating SAN storage to a virtual database server on VMware

I am relatively new to Linux and 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.

NAME
pmdavmware - VMware performance metrics domain agent (PMDA) DESCRIPTION
pmdavmware is a Performance Metrics Domain Agent (PMDA) which exports metric values from a (possibly remote) VMware virtualisation host. This implementation uses the VMare Perl API (refer to the online docs at http://www.vmware.com/support/developer/viperltoolkit). VIPerl is a prerequisite for this PMDA, it needs to be installed and configured before attempting to use this agent. It is highly recommended that you test your VIPerl installation using the demo programs that are shipped with VIPerl, before attempting to use this PMDA. INSTALLATION
In order to access performance data using the VIPerl API, it is necessary to be able to login to the metrics source. Hence, a valid VMware server name, user name and pass word are needed by the PMDA. These can be passed in on the command line (via the pmcd.conf file) or via a vmware.conf file in the PMDA directory. # cd $PCP_PMDAS_DIR/vmware # [ edit vmware.conf ] This file should contain three lines, such as: $server = 'vm.server.net'; $username = 'XXXX'; $password = 'YYYY'; Once this is setup, you can access the names and values for the vmware performance metrics by doing the following as root: # cd $PCP_PMDAS_DIR/vmware # ./Install If you want to undo the installation, do the following as root: # cd $PCP_PMDAS_DIR/vmware # ./Remove pmdavmware is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is installed or removed. FILES
$PCP_PMDAS_DIR/vmware/vmware.conf configuration file for the pmdavmware agent $PCP_PMDAS_DIR/vmware/Install installation script for the pmdavmware agent $PCP_PMDAS_DIR/vmware/Remove undo installation script for the pmdavmware agent $PCP_LOG_DIR/pmcd/vmware.log default log file for error messages from pmdavmware SEE ALSO
