2012r2 iSCSI Cluster SAS MPIO

Hi,

we are building a iSCSI failover cluster for Hyper-V and vmWare. We use 3 JBODS directly connected to 2 nodes with dual-SAS. There will be a tiered StorrageSpace with Enclosure-Awarenes. My question now is, which SAS-HDD MPIO policy do i have to set inside the disk settings of the hardwaremanager? Failover or Round-Robin? I think this should be Failover??

Thanks for helping!
