We are working with several ESX 4.0 U2 hosts and NetApp FAS2050 (Ontap 7.3.3) with Active/Active controllers configuration. We are following the TR-3749 NetApp and Vmware vSphere Storage Best Practices document to make sure we stick to best practices
I'm a confusion regarding enable ALUA or not in the iGroup since the documentation that I have been reading from NetApp and Vmware is not that clear enough and some people is recommending that ALUA should only be enable if you are using Fiber Channel protocol (but it is not our case)
My question are:
1. Should I be enabling ALUA and use the VMW_SATP_ALUA (SATP) with Round Robin MPIO policy ?
2. Should I NOT be enabling ALUA and use the VMW_SATP_DEFAULT_AA (SATP) with Fixed MPIO policy despite VSC 2.0 is selecting RR ?
I will appreciate any suggestion or other experiences on this.
