VMware ha high-availability cluster

Cost-effective high-availability solutions for all applications

When an ESX host is down, other ESX hosts wait for 30 seconds and then ping again if it fails to detect it. If it fails, the system enters the storage to check whether the VM file is locked. If it is not locked, it is automatically added to its own resource pool and then started to the virtual machine. If an ESX host is not shut down, but the network is lost for other reasons, it will ping other hosts, the vmkernrl gateway set in the console is pinged. If it doesn't get through, it will know that it has a problem, and it will enter the storage to release its own virtual machine and unlock it. Other virtual machines will control it.

Therefore, to implement ha in a cluster, ensure that the resources required by the virtual machines on a host are sufficient on other ESX hosts after the host is crashed, that is to say, the cluster needs to ensure that a host can have enough resources to run the VM on it after it is down.

Vmotion technology allows you to move a running Virtual Machine from one physical machine to another without service interruption.

Dynamic Load Balancing and continuous intelligent optimization ensure the resources required by all applications.
