How to organize fault tolerance in vcenter?

Question

VMware

There are 2 hosts with hypervisors 5.5, now we want to switch to 6.
How to organize the fault tolerance of a machine with vcenter, so there were cases that 1 host hung up, and when it was rebooted, vcenter was lost, in which you then had to shaman.
Search didn't turn up anything. :(

Answer 1

Either fault tolerans or ha cluster.

Answer 2

Fault Tolerance cannot be organized without a cluster. For a cluster, you need at least shared storage for VMs, and even better 2 replicated ones (so that there is no single point of failure). If it’s hard on the budget, then you can set up a backup of the entire virtual machine using veeam or something else to a neighboring host so that you can quickly return the machine to service.

Answer 3

there are 2 open-e configured as activ-activ iscsi, so there is no failure, the cluster between the machines is also assembled, but if they stupidly turn off the host by rebooting the machine, they don’t migrate, since there was vcenter on the hung host, but I’ll try Fault Tolerance thanks.
Do I need a separate network interface or can I just put it in another vlan? Do you eat a lot? otherwise the host has only 2 uplinks of 10 gigabits each

Answer 4

1. vSphere High Availability
2. vSphere Fault Tolerance
3. Microsoft Failover Cluster
