Folks,
I'm using vSphere Enterprise Plus 4.1.
I've read up on the RDM's v VMFS debate. However, the arguments for VMFS seem to assume you are planning to run the operating system from the volume. In this case VMFS wins.
I have a VMFS volume set aside for a couple of my operating systems already. But one of the VM's will be a file server. I'm planning to add 7 x 500GB LUN's to this VM. I don't plan to make snapshots of these volumes.
It seems there is very little to skew the argument one way or another in favour of either storage type. In the absence of any compelling reasons, I'm slightly siding with RDM's. It will give me more flexibility to 'swing' the storage if I ever need to upgrade and I won't get the red exclamation marks appearing in vCenter like I would by filling up my VMFS volume with a virtual disk file.
Can I ask for some advice on what would be a 'best practice' for adding volumes which will just be used to store data?
Regards,
Michael
