Hi guys, I have a couple of questions regarding HyperV Server 2012R2 Cluster Failover with High availability.
I have 3x R720 DELL hosts with H700 RAID and no NAS, only locally attached disks (DAS?) since the host have enough storage and buying a dedicated storage is currently not an option i would like to set up HA or at least some kind of fault tolerance.
VMs hosted on the servers would be Exchange, DC, SQL, and IIS. I would just like a general guidline how to accomplish this so I can investigate further.
Is it possible to have everything on one host and have it highly available on the second one? Like a highly available replica ( if that even exists). A lot of stuff i have read involves some kind of a storage or virtual SAN but i am thinking that it should be doable with 3 servers.
And on a final note, is it better to do the HA part or just make replications where they are possible. (SQL, IIS and VPN servers can be replicated, for Exchange i would set up DAGs)
P.S. Small downtime (max 30 minutes) is an option if anyone is wondering and we have low workloads ( 100-150 users )
