Thanks for the feedback Donald. I should have mentioned, both arrays are configured as RAID6.

Given the size of my infrastructure (Very small, two PS4XXX series arrays and four R610's) I believe I will just leave the members in their own pools until such a time as I encounter any performance restrictions.

Capacity based load balancing does not work well for my needs, I was hoping the filers would tier the storage at block level, but it appears to be done at volume/LUN level, still  a bit too used to NetApp.

additionally, thank you for the recommendation of modifying the NOOP_TIMEOUT value, I had read TR1091 prior to implementing my PS4100X array a couple years ago, so I believe the rest of the configuration items should already be done to best practices, with the exception of the heartbeat vmkernel ports, I guess I no longer require those :) Any harm in leaving them there?

Thanks for the follow up again Donald, really appreciated. We are planing to migrate to vSphere 6 for our cluster in the near future. I'm still doing some reading on VVOLs, but I did watch the EQL 8 presentation that gave an overview of the VVOL functionality.
