Application HA supports hardware failure and software failure with a quick recovery time ( RTO around 1 mn or less).

A shared disk cluster is complex to deployĪpplication High Availability vs Full Virtual Machine High Availability.

SafeKit is a shared-nothing cluster: easy to deploy even in remote sites.

Complex hardware clustering with external storage or network load balancers.

A simple software cluster with the SafeKit package just installed on two servers.

Software clustering vs hardware clustering This will be the case, for example, when switching between primary and secondary roles.

Thus the application inside the VM is restarted. "stop" is recommended because it causes the shutdown then the reboot of the VM when the module is stopped and restarted. "off" turns off the VM (power off) when the module is stopped."save" saves the current state of the VM (suspend) when the module is stopped."stop" shutdowns the VM when the module is stopped.The NORMAL_STOP and FORCE_STOP values can be "stop", "save" or "off": This directory will be replicated in real-time by SafeKit. We assume that all VM1 files are in D:\Repli-Hyper-V\VM1\ (see prerequisites). Enter in VM_NAME, the name of the virtual machine (VM1).Put in VM_PATH, the root path of the replicated directory (D:\Repli-Hyper-V).But, you can define a private network if necessary.

Normally, you have a single heartbeat network on which the replication is made.Choose an automatic start of the module at boot without delay.
