Downtime duration if a host fail in a 2-node configuration
Posted: Wed Mar 04, 2020 7:53 am
Hello everybody,
I am interested in testing a StartWind Virtual SAN into an Hyper-V 2-node failover cluster and understanding the behavior of this configuration in case of failure of one of the two hosts.
Let's consider that just one virtual machine is running on such a basic configuration and that a failure (disaster or power failure in general) occurs on one of the two hosts.
Here you are few questions about which I would really appreciate your answers...
1. How would the configuration act in order to preserve the running state of the virtual machine? Would the machine be moved together with the RAM content or would the virtual machine be rebooted from scratch on the other host?
2. According to your experience, simulations, tests, how long would be the duration of the downtime when the failover mechanism moves the virtual machine on the other host? (Less than 10 seconds, less than 30 seconds, less than one minute or longer?)
3. Is it possible to implement the described configuration without a domain (having the servers just into the same workgroup)?
Thanks in advance for your support
Best regards
Giulio
