Plain Virtualization

There are lots of content available nowadays especially with the Broadcom acquisition of VMware, there are many on how to migrate off VMware and feature function comparison. One of the great content that is easily digestible from 2TekGuys . Below is a breakdown from the video on the features that was mentioned available on other hypervisors in comparison with VMware vSphere. I am not going to go into feature beyond mentioned in the video. Here are the list of features mentioned: Load Balancing : Moving using live migration of virtual machines (VMs) between hosts to due to contention. Backup : Support of backup from popular backup vendors or from hypervisor vendor themselves. Storage : Able to utilize external network storage/SAN or hypervisor own hyper-converged storage only.

Many have asked me whether if a cluster can be mixed with different versions of ESX/ESXi servers.  The answer is yes even down to ESX/ESXi 3.5, however for version 3.5, you would need to cater the legacy license server.  Please refer to the documentation here . Here is a demo of a setup I did with ESX 4.1 and ESXi 5.0 in the same cluster with HA and DRS enabled managed using a vCenter 5.0. Please note that upgrading VMware Tools to the latest version will still be supported on lower version of ESX/ESXi servers as it only update the OS drivers.  However, upgrading the virtual hardware will only allow it to be supported on the latest ESXi server. In such, that in consideration when doing your migration and upgrading of your vSphere environment and perform the virtual hardware upgrade last if possible unless you have enough resources to cater for your HA.
