ESXi performance efficiency

[AIC2000]

Hello,
I've been looking at installing PFsense in an ESXi environment for the last few weeks, and have read through many topics on this forum.

The only question that seems difficult to find the answer, is that in many guides it is recommended to setup "ESXi Management" on a different subnet. What exactly does this mean?

One example of this is a post on here from 2012: https://forum.pfsense.org/index.php?topic=45789.msg257663#msg257663

1. Does it mean I should install ESXi and configure its own Gigabit LAN ethernet port
2. Does it mean I can just use the ESXi Management console access on the same Gigabit LAN ethernet port and just change the Subnet and IP range for it
3. Does it mean I should install ESXi and configure its own Gigabit LAN ethernet port AND put it on a seperate subnet completely?

I know that PFSense is very flexible on this with ESXi, I just want to give it the best chance of having good performance.

Thanks in advance for your help :)

1. Does it mean I should install ESXi and configure its own Gigabit LAN ethernet port
   Depends. I only to that for critical environments. Usually I use the same port as LAN.

2. Does it mean I can just use the ESXi Management console access on the same Gigabit LAN ethernet port and just change the Subnet and IP range for it
   Yes, set. Just set different VLANs in ESXi.

3. Does it mean I should install ESXi and configure its own Gigabit LAN ethernet port AND put it on a seperate subnet completely?
   If it's a supercritical system, then yes.

I've ran pfSense under ESXi for 4-5 years or so, with no problems at all, this in a small environment with about 600 users. Always used same port for VMManagement Network and LAN, different VLANs ofc. There is only supertiny amount of traffic on management-network.

Thanks that has given me confidence to go forward with just 2x ports.. Is it difficult to setup the vlan in esxi? I've found rough text guides but nothing too detailed, do I need to create a route for the vlan so I can access the network over my main LAN?

Thanks again
