Setting up a separate network for VMWare and SAN
Posted on 2013-12-18
Hi everyone, trying to understand in a little bit more detail how I could go about setting up a separate physical network to segregate a VMWare Server & iSCSI SAN traffic from the rest of the LAN. I'm not currently using switched that support any VLANing.
My VMWare Server has multiple NICs as does my SAN. Currently I have them assigned static IP addresses of
I'm a little confused about a few things.
1.) To separate their traffic is it as simple as adding another physical switch that has each of their NICs plugged into the switch (existing NICs and IPs referenced) and a 3rd cable connecting the switch to the main network switch? Or does this defeat the purpose?
2.) If option one is incorrect the proper way I would assume would be to add another physical switch and configure a 2nd NIC on each device and plug that into the new separate switch and setup the new NICs as the way the VMWare Server and SAN communicate. Is this correct? Leave the current NICs and IPs there so that I can remotely manage the appliances right?
3.) If option 2 is the correct idea what IP address/subnet do I configure for the new NICs? Can I use my existing subnet or is that defeating the purpose? IE: could I setup the new NICs as
Subnet - 255.255.248.0
Gateway - 10.200.0.1
Also is it relevant that the new NICs & switch wouldn't be connected to the main network and therefore be unable to reach our gateway of 10.200.0.1?
Thanks! Any advice or help is appreciated!
