  • 1.  Vmware ESXi Server Redundancy / Failover

    Posted Mar 05, 2023 02:29 PM

    I have one Physical HP Server 1. In that server Vmware ESXi Installed. In ESXi there is two virtual machine.

    Now i want to purchase another Physical HP Server 2 and i want full synchronize of HP Server 1 (Vmware ESXi with two Virtual machine).

    So that if HP Server 1 down due to any power reason or any other then we can get all data from HP Server 2 without time/data loss.

    What to do. please help and suggest me.

    vmotion need to be configured and datastore should be visible to both host.

    Euuh, vMotion is not what helps with failover, that is vSphere HA, this is what you should configure. How it works and what you require is documented well: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-33A65FF7-DA22-4DC5-8B18-5A7F97CCA536.html

    You need a shared storage to achieve the HA on the Virtual machines using the Vmware Fault Tolerance technology. Doing this you will have minimum downtime and all you data will be replicated from one server to another server, I PRECISELY MEAN if one server is down the other server takes over all the VM with bare minimum time. you should check the prerequisites here

    Thanks

    I would go even further, based on his statement about "... and I want full synchronize...", and suggest that that really suggests Fault Tolerance. 

    However, based on the context of the query and the OP's starting point, I would imagine that going as far as getting vSphere with sufficient licensing for HA, vMotion or even FT is going to be stretch. His system is likely going to be little more than two standalone hosts, so even the required type of storage might be stretch. So wouldn't it be more likely that the solution may lie within the guests he is using, like WSFC in Windows Server?
