This is the third and the last article in the series related to How to build a Cluster based on VMware. In the first article, we saw Cluster Technologies types and understand how to install VMware ESXi, in the second article we look at how to deploy the vCenter Server Appliance (VCSA) 6.5., and now we will look at how to configure VMware HA Cluster.
To build a cluster, VMware uses from 2x to 32x ESXi servers that are managed using vCenter. To build a cluster, you also need a shared store. It can be implemented with VMware vSAN or with storage support providing access via Fiber Channel, iSCSI or NFS. The storage stores the virtual machine files that are available to all the cluster hosts at the same time. It is due to the overall storage and independence of the virtual machine from the physical platform that rapid migration/recovery of virtual machines is achieved.
At the end of July VMware has released vSphere Update 1. In fact, this is the first their update for vSphere 6.5, VMware’s major product. There are also other updates apart from the mentioned one. VMware Site Recovery Manager has been updated to the 6.5.1 version and VMware vSAN has been updated to 6.6.1. This news will be highlighted in further to prevent you from being overwhelmed by the massive lists of the Release Notes.
