Understanding hyperconvergence with Vmware?

hi guys

I'm trying to understand vmware hyper convergence in very simple terms and its advantages?

In the current place I'm in, we have multiple sites, each site has a Vmware cluster, vSAN's and also have a cloud footprint.

Does hyper convergence in my current environment mean, mixing the environment we have on site along with cloud? I'm trying to understand this better. If you could explain it in lamen/simple terms that would be great.

Thanks for helping
Yash

That diagram is exactly the same as my environment.

We have x5 physical hosts, with Esxi hypervisor on them and set up in a cluster. We have a vswitch and vSAN setup. So I can basically create a Virtual machine and assign its resources from host 1, use storage that is part of the pool storage and its networking layer assigned by what has been made available to host 1.

Is what I have described hyperconverged? The reason I ask is that I could have implemented this setup, without knowing that there is a technical term for it. Then when a techie turns around to say 'we need to have a hyperconverged environment', I can say 'we already have that environment, so please elaborate'

Yes So all you need is inside the hardware no need to setup LUNS on the SAN etc..

Hyper-convergence puts storage/compute/network in 1 BOX rather than in a rack

Probably known previously as cluster in a box

VMware did have EVO Rail now replaced with VxRAIL

This is Hyperconverged.

So does this mean we no longer need fibre channel switches? We no longer need SAN trays for extra storage?

Instead we just keep on buying physical servers of various types, i.e. one DELL, one HP, One IBM with storage in them and put them together into a cluster? Whereas before, all servers needed to be of the same hardware manufacturer to work in one cluster?

How does HCI compare to what I was doing 3yrs ago with multiple esxi hosts in a cluster, fibre channel switch, SAN trays? I'm not getting it.

that's rubbish! Never been true. You can always have different vendors in a Cluster!

Everything you need is all in the same box....so effectively you just purchase boxes which includes everything.

Servers, SAN, Storage, Switches, Network - turn on and your done! (almost)

At present you've purchases a server, storage, fibre channel switches, and connected them all together in a  rack with cables

if you put ALL of what you have in a cardboard box it's  Hyperconverged

Fair enough, but i recall being told that the Esxi hosts in a cluster needed to be of the same make/model.

Now this makes sense. Previously everything was separate and it meant someone had to configure hardware connectivity between SAN, fibre channel switches, esxi hosts etc. Now, they're all in one.

This is the answer I was looking for. Thank you.

That's not true about same make and model.

What is true you cannot Mix Intel and AND CPU hosts well you can but vMotion is never going to work between Intel and AMD

That's AMD- autocorrect!
