Vmware Vsphere - Multi-machine Cluster

Question

I’m trying to understand the concept of Vmware Vsphere. As far as I can see in the documentation and in video-lessons, for example I have a 5TB HD machine and 32 GB of RAM. On this machine I install the operating system Vsphere. On top of this operating system I create my virtual machines. Remembering that I have to distribute to my virtual machines the resources of my physical machine: 5TB HD and 32 GB of RAM. Now comes my question: I have another physical machine, with 8TB of HD and 16GB of RAM. I want to "aggregate" this machine so that its resources (HD and RAM, for example) are added to the resources of the first physical machine, and thus can also be used by virtual machines. That is, now I would have to distribute to my virtual machines 48GB RAM and 13TB HD. Does that make sense, or is my concept of Vmware vsphare completely mistaken? Actually has to "add" two physical machines in a Vmware Vsphare system?

Answer 1

Paulo, your doubt is very interesting, when we talk about a Vmware cluster your resources can be added more virtually, even having a 32 GB memory machine and another with 16, will not initially be able to create a 48 GB memory, If this is necessary for your application you can use another type of resource as cluster, such as SQL server cluster or other type of application having 3 machines with 16 Gb of memory totaling 48. In some views Vcenter comes to demonstrate these resources together but Vcenter must divide them between the Vms in its cluster.
