VMware Cluster as create and enable HA from VirtualCenter.

Posted by Xaus Xavier Nadal 1st on December 2012

VMware ClusterTo create a VMware cluster we have an essential form of a VirtualCenter (vCenter) and therefore of physical servers ESX 2 installed.

What we want to install a VirtualCenter server and put under a vmware cluster?

For various reasons including: vmotion (You can move virtual machines from one host hot ESX to another), Storage VMotion (Included by default in the 5.1 version of the standard license) you can move the virtual machine datastore hot (awesome) ... if a LUN is no space you can move the machine to another LUN without losing service, Fault Tolerance, ... With all this we make it easier for example spend all virtual servers from one physical server to another and so can upgrade ESX smoothly.

We from here I highly recommend it.

You can follow the following items according to your preferences, to install VirtualCenter if you have it already installed.

When you have installed the vCenter and you may access it through a vSphere client, only you should follow these steps that we show below:

Create new Datacenter.

Create new cluster.

Add Hosts.

As set Vmotion in VMware ESXi without fear

Posted by Xaus Xavier Nadal on October 22nd 2012

vMotionvSphere5Vmotion VMware is a technology that enables the migration of virtual machines from one ESXi host to another host without losing service.

What we will show in this article is how to configure Vmotion in 2 ESXi hosts connected together by a dedicated network cable.

2 really recommend using network cables since in vSphere 5 you can use multiple network connections to load the VMkernel swing between the 2 cards and much reduced time migration of a virtual machine from one host to the other. (Really though migration between hosts is very fast, we will see the end of the article when you move a hot machine).

requirements:

Having a Virtual Center.

 

2 have physical servers with ESXi installed.

 

Having a Gigabit network cable to connect from one server to another directly.
