1.  Be aware that Oracle's official position is that they do not support Oracle in a virtualized environment beyond the operating system.  If there is a problem and you need Oracle's support, they may very well tell you to put it on a physical server before they will support you.
2.  Whether you use VMDK's, NFS, or LUNs is going to depend a lot on which OS Oracle is running on and how you plan to protect the data.  Also, which version of Oracle you are running.  For instance if you are running Oracle 10g in a Windows environment then NFS is out of the question.  If running 11g in the same environment, then one could use Direct NFS with Oracle.  In a Windows environment Snapdrive for Windows 6.3 has no issue with taking snapshots of LUNs or NFS volumes, prior versions could not deal with NFS so you had to use LUNs if you wanted to use Snapdrive for Windows to handle taking snapshots of your databases.

Hi

Im setting a new Oracle Database solution to replace a old Oracle RAC on EVA8400.

After reading Oracle Databases on VMware vSphere 4 - Essential Deployment Tips i got a few question still needs answered.

Our new storage is a FAS 3240 7-Mode

We have a SATA and SAS aggregate and 1TB Flash cache available.

SAS 1  Raid Group (16 disks)

SATA 4  Raid Group (56 disks)

 

 

 

Whats the recommendations for Datastores and VMDK's?

From i can gather i need to create a volume dedicated to Oracle and present(NFS) it as Datastore for Oracle only.

And create VMDK's like this:

 

VMDK-1 OS from another Datastore

 

Oracle Datastore

VMDK-2 Oracle Binaries
VMDK-3 Oracle data
VMDK-4 Oracle Redo
VMDK-5 Oracle Archivelogs

 

I have 5 databases so 5 VM's where i create a volume with Datastore for each?

 

Would like input from the list how others have done it.
