vSphere Essentials Best Practicce vCenter Server: Virtual or Physical?

often vCenter Server configuration should be 4 vCPU and 16GB RAM!
https://www.experts-exchange.com/questions/28897802/vmware-vsphere-6.html?anchorAnswerId=41365611#a41365611
I currently have vSphere Essential 5.5 on a DL380 G6 ESXi 5.01 server, My vCenter Server is running on a Windows 2008 Server that mainly acts as PrintServer, but does not have that many resources. Currently has 1 vCPU & 4GB RAM.
I have always felt insecure running vCenter on the same ESXi that is supposedly controlled. Seems like if the server is down unless you use iLO you cannot access the settings or place in maintenance, or take out of maintenance.
Plus with the four servers running here I have no where near enough resources for 4 vCPU & 16GB RAM.
Would I be better off moving vSphere to a spare physical server (DL360 G5) that is Windows 2008 R2 with ample resources?
And how would this be accomplished? Uninstalling from VMWare server and then re-installing on physical, or is there more to the process?

Yes I currently have 4 VMWare servers. I will be adding RAM on Friday as we need to create a new windows 2012 R2 DC prior to migration to a new domain. Just trying to cover all the bases.
currently maxed out for vCPUs, I hope to be able to check to see if Hyper-threading is enabled.

As usual your input is gratefully accepted.
not to mention that vCenter is available as an OVA application for a virtual install. it doesn't get any easier than that
it's not really an OVA any more! but very easy to install! (based off an OVA!)
see how easy here, with my Fabulous EE Article

Responded based on the use of VMware 5.5. you are absolutely correct if you are using 6.0. it is good that you added that to qualify my answer. thank you.

today I do not have a slow initialization, I cannot connect to vSphere web Client at all with either IE or FF:
"Internet Explorer cannot display the webpage"
"Firefox can't establish a connection to the server at localhost:9443"
Any ideas?

VMware
VMware, a software company founded in 1998, was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies. VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture. Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

vCenter Server does not control the host or VMs, turn if off, the world is not going to explode!!!
Personally, I would not add any other roles to a vCenter Server, and I would increase your CPU count to at least 2 vCPU (2 sockets, and 1 core), and for a small installation, that's
fine...
The more memory and vCPUs the better it performs, and one day, there will be no vCenter Server for Windows, it will be an appliance only (virtual based on Linux!)
Remember vCenter Server is just a management server, if vCenter stops or is off, your VMs keep running.
You can always connect directly to the host to controls VMs, and start and stop vCenter Server, put the host into management mode,
My recommendations are based on number of hosts and number of VMs, and whether you also have SQL installed on the same vCenter Server.
vCenter Server can be run as a virtual server, and there are many benefits, in running it as a VM, e.g. Backup/Restore and DR.
So
how many hosts do you have ?
how many VMs do you have ?
Do you just have a single Host with 4 VM s?
