Dell R620 ESXi 5.1 Host with 4 Gigabit ports

Guys,

I have 2 Dell Virtual Servers.  One is the R620, and the other is the R610.  Both have 4 gigabit ports on them.  Right now the R620 is the most important as it has about 10 Servers on it.

I am only using 1 Ethernet cord to connect each server to our 2 Cisco 2960 switches.  Beside having redundant nics what is the benefit of using the ports?  Should I be using all 4 on each? If so, can you please tell me how I would setup more than one nic?  I was thinking maybe have 2 Ethernet cables connected on each server going to both switches, but I don't know what IP to use, or how I should go about setting this up?

Thanks!

The benefit of having multiple nics is

1. reduces single point of failure, and better resilience

2. higher throughput (if required)

Example with 10 NICs
you do not need to use IP Addresses, you are correct, you connect two NICs to two ports on physical switch1, and two NICs to two ports on physical switch2, but you need to have the correct configuration on the physical switches, and ESXi configuration.

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