I have two new DELL servers and each one has two NICs in each server. When i look at the properties on any of the NICs, I see several properties listed such as,
Client for Microsoft Networks
File and Printer Sharing for Microsoft Networks
Internet Protocol (TCP/IP)
These are all enabled. There is also an item that is called,
Network Load Balancing
This item is not enabled. The description for it says, "This component provides TCP/IP load balancing functionality"
The way I read this is that if this item is enabled on both NICs in a server and the NICs are given the same IP address, then they will act as one virtual NIC and will share the load on that server. That's just how I interpret all that stuff. However, I just did a search on EE and read around 12 questions regarding two NICs in a PC and Load balancing and I do understand the concept of Load balancing in regards to clusters of servers, etc but the impression I got from reading the Q & As was that that's not what "load balancing" is. Is it? Is there this other type of load balancing and does it help on, for instance, a web server with medium demand? Is that then dependent on having the connections from those two NICs going to different switches to realize any type of gain on throughput? I am totally confused on this one. Also is it possible to do a reservation in DHCP for that address when you have two different hardware MACs?
