vmware configure management network option

Medium Priority

on the esxi os, I see there is a configure management network option. In side the menu, I have option to use all network adapter for fault tolerant and load balancing. I have the HP proliant dl380p, there are 4 network adapters... should I enable all of them?

And I haerd the best practice is to use one port for management and other for vms...? Will I still be able to do this if I enable all the network adapters in the configure management network option? and how do I do that?

If you have Four NICs, you need to work out which NICs do you want to pair and team.

You can use all four nics, added to the vSwitch0, and then use this vSwitch for Management Network, Virtual Machines.

or you could seperate into different vSwitches, see example

NICs
If you want to read more on networking in VMware ESX/ESXi, then I recommend the following:-

I would also recommend reading through the Networking Sections of the following guides to gain a better understanding of Networking in VMware ESX/ESXi.

Pages 13 - 73 Discuss Networking in Detail, including trunks, VLANs, switches, and load balancing

If your have two subnets - one for management network, one for your VMs then you canuse one port for managment and other three ports for your VM networks.

If you only have one subnet for your VM, then you can use management in the same network.

You can also checkout to this KB we recently answered on how to design a good VMware envoirment.

Hope this info helps

hi hanccocka, I am not sure if I understood...
so now I have enabled all the nic in "configure management network"
now below, I see all my nics here. I only have one subnet and I just want to put all vms and existingserver and workstations in the same network.
I just want to use one for management and others for vms.... so now do I have to do any configuration?

well you may want to check if that NIC is supposed to be running at 100MB ?

also, before you may any of these changes, and bring the NICs out of standby, you need to check your teaming policy for you physical switch.

but to bring the nics out of standby, you move them up, but at present 1,2 and 3 are not connected.

I checked the spec it's 1Gb 331FLR Ethernet Adapter 4 Ports
I am not sure what you mean " teaming policy for you physical switch"? we have same management switches here... I have to make change on switches first?

 to bring the nics out of standby, you move them up? not sure what you mean...

After I plug all ports to my switch with my current setting, what will be the port the vms and management console using?

if you want to use ALL four nics connected to your physical switch, physical switch network configuration maybe required,

you need to investigate why, you current NIC is set to 100MB before continuing.

If you edit the Properties of the vSwitch, you will see the NICs currently in standby, there are Arrows Up and Down, that allow you to change the order.

The Management Console and VMs will use the same vSwitch, as it does currently, but your vSwitch will be connected by four nics to the physical switch.

I think it's because my switch only support 10/100 mb/sec
It looks it's not easy to set it up... this is what I have now after I plugged in all cables.
So now it's only doing fault tolerant and load balancing right?
Do I see big difference if I go with the Teaming NICs? I only have 3 vms running here.

I foudn a short video http://www.youtube.com/watch?v=Hx9FAo7_H2k
so if I follow this video, do I still need to do something on my physical switch?

You will notice, very little difference, with three teamed NICs!

but you will have fault tolerance.

The video is fine, but you may be required to change physical switch configuration.
