Hello Pasi,

Thank you for your email.
Let me explain the setup more clear, sorry for the confusion.

I have 2 Dell R410 and a shared FC storage,
I have created a Centos 64 bit VM on this pool and attached a disk.
The disk comes from shared cloud storage and it was created while installing the VM.

I'm sorry but I did not understand this part
"passing thru HBA VF to the VM ? and using the VF driver in the VM ?"

Thanks for help.

Regards,
Rushi

So the subject mentions SR-IOV so does that mean you're
passing thru HBA VF to the VM ? and using the VF driver in the VM ?

Also: How does the storage perform without any virtualization,
ie. from Linux on baremetal.
