Re: Slow Disk Performance on Native SAN for Hyper-V

Hi. Thanks for the reply. I am using GPT volumes and the Atto test I showed above is on a GPT volume. Any other ideas about what the problem might be?

What would be the most effective way to use the two 10G ports to get maximum perfomance? I understand I have to connect the two serv...
