I have seen a few discussions about LSI Logic SAS Controller and paravirtual iscsi controller.
We have several VMs with LSI Logic SAS Controller and they are running without an issue, I am not sure whether it is necessary to change or not. I was asked to add a few disks to our Exchange server which is running with LSI Logic SAS Controller, I am thinking of adding a paravirtual iscsi controller (iscsi 2, 0)for new disks.
Experts out there, is it recommended to keep both LSI Logic SAS Controller(iscsi 1,0) and paravirtual iscsi controller (iscsi,2,0) on one server?
or Should I stay with the LSI controller or change all to paravirtual do not run with both?
