Without vCenter, can we maintain or manage multiple ESXi servers, vMotion, and SvMotion?

Or, Can we use vMotion capabilities of VMware on standalone ESXi servers?

Or, What is vMotion and How it works?

Question originally posted by a TechiesSphere reader:

Without vCenter can we maintain two ESXI servers and vmotion svmotion?

 

Understanding vMotion

vMotion is a procedure or task initiated by admin manually or system automatically to move a VM from one to another ESXi Host in case of load balancing or redundancy balancing.

If you have two ESXi servers separately and no cluster, vMotion is having no role to play.

However, if you want to manage the ESXi servers separately like standalone servers, you can do that, but to be able to use vMotion, you must have to add these two ESXi servers in to a cluster and enable HA.

You may refer the below KB for more details and explanation on this topic.

How VMware Virtual Machine vMotion works?

What is EVC in VMware, and how to enable it?

Or, What is EVC in VMware?
Or, How to enabled EVC in VMware?

What is EVC in VMware?
EVC stands for Enhanced vMotion Compatibility. It is used for enabling hardware compatibility between different hardware types of ESXi hosts so that we can easily migrate Virtual machines from one to another host even if the hardware of ESXi hosts are different.

If EVC is not enabled, you can't migrate a Virtual machine to an ESXi host which is having different hardware version with compare to another ESXi host.

Simply we can say that EVC ensures that all hosts in a cluster are VMotion compatible, even if they are not from the same hardware category.

How to enable EVC (Enhanced vMotion Compatibility) in VMware ESXi Cluster?
Few easy steps and you are done with EVC configuration for your ESXi cluster.

IMP Note: Before enabling EVC mode, you must shutdown your all VMs of that particular ESXi host on which you are going to enable EVC mode and migrate VMs to another ESXi host/cluster if possible.

Steps:
- Log in to vCenter Server by using VMware vSphere Client
- Right Click on your Virtual Datacentre Cluster
- Go to Edit Settings
- Select VMware EVC in the left Panel
- Click on Change button to edit the EVC settings
- Select appropriate EVC settings for your Virtual Environment from the drop-down list...
- If validation succeeded with your desired CPU selection for EVC, you should be happy...
- Click OK twice to EVC mode dialog box and cluster setting dialog box...
- Power on your ESXi host.
- Migrate VMs from another host to this host to check if things are done correctly

You are done now... cheers…

Description: Friends, if you were using update manager on vCenter server with windows server operating system platform and now want to use it with vCenter appliance, or if you have installed vCenter appliance and now want to use update manager with this appliance, you may get all your answers here.

 Scenario: I have recently migrated from windows based vCenter server to vCenter appliance. Now I want to use Update Manager with this vCenter appliance but the challenge is, update manager cant’t be installed on vCenter appliance or Linux based OS, it can be installed on Windows based OS only.

There are two stages in this article, in Stage-1 we will see how to install update manager and integration of update manager with vCenter appliance. In Stage-2, we will be enabling update manager plugin for vSphere web client and vCenter traditional client.

Enabling client plugin on vSphere web client and vSphere traditional client is must because only after this, you would be able to get the Update Manager icon in your vSphere clients.

So now, I have my vCenter server running on vCenter appliance and going to install update manager on windows based operating system and while the installation of Update Manager, I will integrate it with vCenter appliance. Latter in stage-2, I will be enabling Update manager plugin with my vCenter server appliance using vSphere web client and vSphere traditional client.

Stage-1/Steps:  Installation and integration of Update Manager with vCenter appliance

Download the VMware vCenter Server ISO for Windows from MyVmware download portal ( In my case its, VMware vCenter Server 6.0 3a and module for Windows )












Mount the ISO on the Windows Machine (I am having Windows Server 2012 R2)













Right Click on Autorun executable file > Choose Run ad administrator
















Click on Install



















Wait for the Installation of SQL Express completion



















Click Next



















Accept the license agreement terms > Click Next



















Choose Download updates from default source immediately after installation > Click Next
