I had this question after viewing Some Hyper-V Hardware and Software Best Practices
We are looking at a new server to replace our aging SBS2011 box. I'm going Hyper-V, but I really don't know if it's worth going to a cluster based on our budget and use. Maybe 1 live + 1 replica. The boxes we will probably buy have 8-10 hot plug. Does it make sense to go with 3 eSSDs (costs have really come down!) in Raid 5 for the host OS + DC/Exchange/LoB Apps (sql, WSUS, SEPM) VMs and put the LoB data on 5-7 10k-15k SAS? I know the newer RAID controllers support this.
