Hi Yordan, HA is definitely the biggest con, as Rohit mentioned. Adding to that, live migrating VMs around the cluster takes a LOT more time as well. For example, it takes "5 minutes" when live migrating VMs in shared storages; however, it can take hours when live migrating from local storages, depending on the VMs root disk size. It is important to consider the time needed for each VM migration, in case you need to offload a host for maintenance or balance the VMs workload across the cluster.
