What should the SCSI Attributes load_bal_policy be set to for best performance?

[Shawn Zehnder]

We have a EVA4400 and EVA6400 both with redundant brocade switches. We're primarily using the SANs for our HPVM Integrity Virtual Environment. The Luns are presented to the host with a round_robin scsi load_bal_policy. This was the default setting when the Luns were presented. What would be the best load_bal_policy option for performance? We're still in the process of getting performance monitoring set up. I was hoping there would be a best practice option that we could commit to now. Thanks in advance.
