Hyper-v 2012r2 CSV disks best practice

Hi All,

When i bing (google ;-)) i can't find much info about this topic (only pre 2012 hyper-v).

Situation:

We have an 8 node Hyper-v cluster 2012r2, at the moment we have 16 CSV luns of 2 TB each. We have about 600 servers running on this cluster, about 37 VM's per CSV lun, the question is as follows:

What is beter? this situation thus more VM's per LUN or break those 2 TB luns into 1 TB luns and divide the VM's so there will be about 15 VM's per lun but more CSV disks in the cluster?

The underlaying storage is a EMC VNX with a single pool auto tiering enabled.

Another question gets in mind what is the maximum CSV disks in a Hyper-v 2012r2 cluster?

Hope you can help.

Thanks!
