vsphere 5 network question

Hi guys

I have 3 physical vsphere 5 hosts and in esx1 I have a dc and vcenter server on a 2003 r2 member server
Currently the dc is doing dhcp but its interfering with the normal dhcp server on the lan so its been suggested to use an additional vswitch for the vm;'s and can somebody please help
I want the management to go via the lan so we can use viclient on the lan and I tried using the security profile but dhcp still got to the lan and cased a problem so I need my vsphere 5 hosts vnetwork setting up better to stop the vm traffic from the management lan

How would the other vsphere 5 hosts need to be configured as they will be holding the vm's in question

all three vsphere 5 hosts have multple nics if I need to use a seperate switch for this

Why not use a dedcicated vSwitch on each ESXi host, with one physical NIC, which is connected to a dedicated physical switch?

Are you DC and vCenter on your virtual server Production or Lab use?

If so why do you have TWO DHCP servers, you can only have one DHCP server per LAN?

- DHCP : You can use 2 DHCP on 1 lan if you split the range between the 2 dhcp Servers. Its nice to have a backup dhcp server if the first 1 fails.   How to configure split-scope using wizard

- Management Network : If your management network and Lan network is 1 and the same segment. Just use your vswitch with the multiple ports and use the standby function to dedicate 1 nic for your management trafic. This way you have multiple nics to guide your traffic of your VMs and 1 for the Managemet but is a nicboard error happens the standby ports will be used to maintain Connection.

eg. NIC1 NIC2 NIC3 NIC4 are added to you vswitch.
Configure the vswitch like this.
Open the properties of your vswitch . Select VM Network en press Edit. Go to tab " NIC Teaming" Select "Ocerride vSwitch failover order" put in Active Adapters NIC 1 - 3 and Standby Adapters NIC 4
Do the same for your management network but then NIC 4 as Active and NIC 1 - 3 Stadnby

yes, you will need a separate physical switch, unless you can VLAN those three network ports from the main lan.

the router had no vlan so I have moved the esx lab to a different location to somewhare that had a router that could do vlan but I am considering using a seperate switch  and used 192.168.x.x for my lab and 10.x.x.x for my lan and added 192.168.x.x to my viclient pc as an additional ip address so I could communicate with vcenter on 192.168.x.x
