Public and Private Network

We have an OLD tower server with 2 NIC cards, 1 card is connected to a public switch in the public network / DMZ and the other card is connected to the private LAN, both NIC cards are on different sub networks

In the NEW blade server Fujitsu-Siemens Blade Server BX620S4 which is in a BX600S3 chassis we have ESX Server 3.5 installed on the blade in which we have a windows virtual machine, the blade servers are connected to the network using a Switch (PY BX600 GbE Switch Blade 10/6+2) within the Chassis, these are 2 of these blade switches for redundancy

The query is, How do we configure the virutal NIC within the windows virtual machine to physically map to 2 physical switches in different networks ?

Hi, in your setup you would certainly need to add a second NIC to your VM. That way your VM gets who networks, two subnets. Each vNIC should be connected to a different network inside the ESX host.

This will only work if your ESX environment has access to both networking segments, either through separate physical NICs to physical switches, or (more likely when using blade technology), a trunk port having multiple VLANs inside which are all brought to the ESX host(s).
