A bit of background to my environment before my question:-
2x Windows Server 2012 Hyper V hosts
No SAN or shared storage at present
4Gbps NIC Team
I am wondering which would be the best way to setup these hosts for redundancy. We are currently using the local storage to hold the VHDs as we want to avoid the SAN route if possible. As I understand it, in order to get no downtime, we need a cluster and for a cluster we will need some form of shared storage be it SAN or iSCSI to a NAS or separate file server?
If not, is there a way that if a host fails, the other host will immediately take on the load of host 1 without downtime or data loss? My idea was to have copies of the VHDs on the DAS of both hosts and then if a host fails the changes are written to the log file to be written to the VM on host 2 seamlessly?
Any answers appreciated and thanks in advance!
