I am setting up a Business Continuity environment. To achieve SAN indipendence I would like to set up VM with two virtual disk: one will be hosted on a SAN, the other on a second SAN.
Disks will be mirrored inside the VM OS by a third party volume manager agent.
I've recently come accross this statement on the SAN configuration guide:
"You cannot use virtual machine logical volume manager software to mirror virtual disks. Dynamic disks in a Microsoft Windows virtual machine are an exception but require special configuration ."
Does this prevent me from doing this setup? Will I be out of support??
This is only supported if you use the dynamic disks option but it doe snot tell you what the special config is so I would suggest raising a support request with VMWARE.
Here is another thread with users trying this so maybe one of them have had more luck:
One of my colleagues pointed out a thing I must take into account:
Swap files for VM are stored on the SAN so probably it is not possible to survive a SAN crash even if I mirror the virtual disk with a software raid inside the VM.
Sbonk... I have to re-think my infrastructure
