Is there any benifit in creating a second scisi controller in a guest VM for say log files in a SQL server or Page file or any other reason.

For example a VM for SQL the disks are OS, Data AND Log on seperate scsi controllers in VM

Would there be a difference in throughput or would this just be a waste

As the controllers are going to hit the same datastore, it's unlikely you will see increased performance. Adding more devices creates more overhead on the Host controlling the VM.

What don't you create different disks, for logs, pagefile, and select different datastores on your SAN, if you are using one, or different datastores.

Selecting different types of controllers however, does increase performance, e.g. Buslogic versus LSI.

As mentioned by "hanccocka"...unless you're placing the info on separate datastores, it's really pointless. You don't save anything, as far as performance goes. It's always best practice to have sys vol, data, and logs separated though on different volumes.
