Under vSphere 5.1 I brought up a new server running Ubuntu Server 12.10. I have read in several spots to have two nics, one for the connection of the server to the network and another one running a class C address to handle Clonezilla traffic. Do I really need two nics? If so, I am not sure how to set this up. I can certainly add another nic to this VM but what would the configuration look like? I have a layer 3 switch at the core of my network and about 20 different vlans with servers all in their own vlan. I have a class A network setup. Below is the current nic config file from this server. I have a separate DHCP server running under Windows Server
auto eth0
iface eth0 inet static
address 10.121.125.43
netmask 255.255.255.0
network 10.121.125.0
broadcast 10.121.125.255
gateway 10.121.125.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 10.121.125.101
dns-search vcs.local
It's recommended to use 2 NICs. You can isolate the packets, especially DHCP. Other machines on the same LAN won't be bothered.
However, DRBL of course can use one NIC as server, and it depends on your need.
