How do i connect my server to 2 networks

Posted on 2011-04-26
Last Modified: 2012-05-11

I have a HP ML150 Proliant G6 server. Which is currently connected to Network1. As i see on the back of the server there are 2 network ports, mgmt & 1/mgmt.

Is there any way i can connect the server to a 2nd network (Network2) using the extra port. Please let me know.

    It looks like this is not a LAN port.  Can you run ncpa.cpl from the run command?  How many network connections do you see?

    i can see only one LAN connection in Control panel.

    but physically there are 2 ports as above.

    The MGMT port is for ILO purposes..  you will need to add an internal PCI Express network adapter..  That's what I had to do with mine, and it works great.

    This port is for ILO (remote managment for the server in case it falls over). As KS suggests you will need to purchase another NIC.

    Not sure why you would want another ethernet connection other than LAN 1 and iLO, but,
    Looks like your best bet is doing as KS says, get a NIC.
    The user Guide says this about management ports:

    Using TCP/IP over Ethernet management port
    You can configure LO100 LAN port access using two different Ethernet ports: the dedicated 10/100
    LO100 management port or through a side-band connection using the server embedded NIC. The
    side-band, shared, or UMP options utilize one server Ethernet port for both server network traffic
    and LO100 network traffic reducing the number of network cables that you must attach to the
    NOTE: Not all servers come with the option of selecting a sideband or dedicated NIC. Some
    have only one option.
    NOTE: Note, when a dedicated setting is selected in the IPMI LAN configuration of the RBSU, a
    dedicated Optional LO100i 10/100 Mbps LAN port for dedicated IPMI management (RJ-45) is
    required to be installed in the server in order for the Lights-Out management to work.
    Selecting a shared Ethernet management port
    1. Power on the server by pressing the Power On/Off button on the front panel.
    2. When POST displays the message, ROM-Based Setup, press the F10 key. If the server has
    an administrator password configured, the system prompts you to enter the password. If the
    server does not have a password configured, the main screen of the BIOS Setup Utility appears.
    3. Press the right arrow (¿) key to navigate to the Advanced menu.
    NOTE: On the ML150 G6, ML110 G6, and DL120 G6 systems, the Virtual KVM and Virtual
    Media functions are not available when used with the Shared NIC function. If you want LO100
    Advanced Pack features on the ML150 G6, use the dedicated NIC mode.
    4. Press the down arrow (¿) key to scroll to IPMI Configuration. Press the Enter key.
    5. Scroll to the LAN Configuration menu by pressing the down arrow (¿) key. Press the Enter
    6. Choose one of these options:
    • On ML110 G6 or DL120 G6, press the down arrow (¿) key to IPMI. Press the Enter key,
    and then set BMC NIC Allocation to Shared.
    • On ML150 G6, set BMC NIC Mode to Shared.
    • On DL160 G6, DL160se G6, DL170h G6, DL180 G6, SL160s G6, and SL160z G6,
    SL170z G6, SL2x170z G6, SL165s G7, DL165 G7, DL170e G6, set BMC NIC Allocation
    to Enabled.
    • On DL165 G7, press the down arrow (¿) key to BMC NIC Allocation, then select
    Dedicated/Shared. Press the Enter key.
    7. To return to the previous screen, press the Esc key, or to save the changes and exit Setup,
    press the F10 key.
    The TCP/IP over Ethernet management port, whether dedicated or shared, is a standard Ethernet
    10/100Mb interface that connects to the network using a standard Ethernet cable. Before using
    the dedicated management port, you must determine the DHCP IP address or set a static IP address.

    if i do connect another NIC, can it serve a files simultaneously to both the networks?

    when you say both networks, are these workgroup networks?

    Expert Comment

    Yes.  You assign it's IP address, subnet mask, and default gateway on that other network and it works great!

    I have my primary LAN adapter (onboard) running on the 10.10.1.x network, and add-in LAN adapter running on the 192.18.1.x network.  Works really well!

    Adding a NIC is one way to do it.

    It would be easier to use a router to connect the two networks.  The server would only need to connect to one of them.

    my scenario is,

    WEBSERVER --> ROUTER1 --> ISP1  (Network1)
    WEBSERVER --> ROUTER2 --> ISP2  (Network2)

    so one server, 2 routers & 2 different ISP's. (also 2 static ip's)

    all i want is share IIS & files over the 2 networks.
    is this at all possible?

    There is no reason why your scenario wouldn't work.  

    There is also no reason why you cannot do:

    As has already been mentioned you will need to buy another NIC since there is only one NIC onboard (plus the dedicated management port which you can't use as a NIC)

    From the quickspecs:

    Parallel       0
    Serial       1
    Pointing Device (Mouse, PS2)       1
    Graphics       1
    Keyboard (PS2)       1
    USB 2.0 Ports       8 total (4 Rear, 2 Front, and 2 Internal)
    Network RJ-45 (Ethernet)       1 (10/100/1000 bits/s)    <-------------only 1 NIC port
