vCentre Appliance(s)

We have deployed vcentre server appliance, to manage our 5.5.0 host and v10 VM's at a remote site.

Were going to upgrade our 2x hosts at our head office to the same version and (had) planned to add these 2x hosts to the remote site vcenter server.  The link between the sites is 4mb.  Would this be an issue for vcentre and the link?

Is it possible to build another vcenter appliance on the HQ site for the 2x local hosts?

or

Would you scrap the remote vcentre server and use a physical server at HQ and add all 3 hosts...?

Thanks

I would add a second vcenter server. What level of licensing are you using for VMWare and vCenter?
I am assuming these sites are not SRM and will not fail over if they go down.

it's not necessary the speed, but the latency of the link. e.g. ping!

Would this be an issue for vcentre and the link?

I've seen links slower working fine, try it.

Is it possible to build another vcenter appliance on the HQ site for the 2x local hosts?

Yes, but you will need another license for it.

Also depends on your vCentre version if you can link them.

With essentials, you cannot Link vCenters, and your MAX number of hosts per vCenter is 3!

So if you have four hosts, you have an issue, with vCenter Essentials (Foundation!).

So you would have to have

2 x vCenter Essentials.....

or Upgrade... to vCenter Standard, and replace all hosts with ESXi Standard.

VMware vSphere Essentials can only manage THREE HOSTS!

licensing is the same for Appliance or vCenter Server for WIndows.

It does not make any difference.

Appliance is actually very good now, and supports many more hosts, and VMs, than what the default install of vCenter Server for Windows does, with SQL Express.

and does not require a WIndows license!

CHI-LTD, If the host where youre appliance fails, HA will start it on the other host, if setup correctly.

If you don't have HA, just connect with the vSphere client to the other host and start the appliance VM from that host in order to have vCenter back...

Incorrect.

vCenter Server or the Appliance is just a Management Server.

You can still connect directly to each host and mange them correctly.

Part 2: HOW TO: Connect to the VMware vSphere Hypervisor 5.1 (ESXi 5.1) using the vSphere Client

But this question was...

We have deployed vcentre server appliance, to manage our 5.5.0 host and v10 VM's at a remote site.

Were going to upgrade our 2x hosts at our head office to the same version and (had) planned to add these 2x hosts to the remote site vcenter server.  The link between the sites is 4mb.  Would this be an issue for vcentre and the link?

Is it possible to build another vcenter appliance on the HQ site for the 2x local hosts?

or

Would you scrap the remote vcentre server and use a physical server at HQ and add all 3 hosts...?

Thanks

and we are going off topic..

so back to these questions?

What are you licensed for ?

VMware vSphere Essentials can only manage THREE HOSTS!

vCenter Server license is for Windows or Appliance.

i guess we could restore a backup of the appliance should the host fail?
or
is it easier to re-install a new appliance/centre.

Again, it's a management server, so there is no failure of virtual machines if the appliance fails or is off!

You should have backups of all your infrastructure, in case of failure.

I think your original question has been answered, and we are no going off topic, and waffling!

Installed the vcenter appliance and not windows server on a remote host.
seems to manage all the 3 hosts (performance wise) fine.
