It really is up to your Design and Management of devices.<br />
<br />
Many organisations have a Management VLAN and all devices, e.g. printers, switches are only accessible using the Management VLAN.<br />
<br />

<blockquote>
I would like to know if Management vMkernel Port and Vcenter should always be in the same Subnet. if that 's the case it means all ESX Hosts will be in the same subnet as Vcenter.
</blockquote>
<br />
this is also not true, because vCenter Server could be at Head Office managing ESXi hosts at Remote Offices, which would likely be on several different subnets.<br />
<br />
There are NO RULES!
</div>


<div>
I thought if Vcenter subnet is in different subnet than ESX Hosts , then L3 device should be in the middle and this will slow down &nbsp;traffic... unless if Management traffic is not that heavy..<br />
<br />
by the way any of other traffic is recommended to be in the same subnet between Source and Destination...<br />
<br />
I know vMkernel Storage Port and the Storage device should be on the same subnet <br />
vmkernel port for vmotion should be on the same subnet, thought latest versions will allow different subnets using TCP stack.
</div>


<div>
Again there are no hardened rules about anything....<br />
<br />
Management Traffic is Management Traffic so very light, but it really depends what you do via Management Port!<br />
<br />
LATENCY is key to network links, especially for vMotion and Long Distance vMotion.
</div>


<div>
which of the traffic is very sensitive to Network Latency:<br />
<br />
vMotion<br />
Storage<br />
<br />
I think if there is Latency sensitivity, then it will be better to <b>AVOID</b> L3 on the path.

Management vMkernel Port and Vcenter Subnet<br />
<br />
I would like to know if Management vMkernel Port and Vcenter should always be in the same Subnet. if that 's the case it means all ESX Hosts will be in the same subnet as Vcenter.<br />
OR<br />
it is OK to have the Management vmKernel Ports on each ESX Host in different subnets from Vcenter Subnet ?<br />
<br />
Thank you

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.
