Switch Type in Network Load Balancing ??

By mikeras ·
Is a layer 2 good enough for Win2K Network Load Balancing or we need layer 3, where you can assign individual IP address to each port?

That's the question we are asking ourselves and don't seem to find the answer.

Any help is much appreciated.

Switch Type in Network Load Balancing ??

Mike,

Layer 3 switches integrate routing and switching to provide high-speed performance without the drawbacks of a flat layer 2 network (broadcast storms, address limitations, spanning loops, etc.) In addition, Layer 3 switches can define itemslike port priority or traffic prioritization.

The two Layer 3s are ...
Cut Through & Packet by packet. Cut through, in the theory world, is faster.

Hope this helps.

A layer two switch is more than adequate for Network load balancing of Win2K advanced server. As long as clients can get Name resolution to your server and the Name requests are load balanced (i.e. DNS Round Robin) then you will be fine. Just make sure that the NICs are on different ports on your switch and the rest should sort itself.

A layer 3 switch would provide slightly faster access in theory, but you would have to configure it correctly. The fact that you can get twice the throughput by sticking 2 NICs in your machine should more than outway the detriments of using a layer 2 switch (providing that your disk subsystem can cope with the requests that is).

The question does not make sense. Layer 3 is used when load balancing-IE..you have more than one NIC in a server. THe switches are a seperate item altogether. When you do add a second NIC, it is only %50 load balancing, not %100 as the previous answer indicated, NT can only transmit from one NIC at a time, but recieve on many.

Using Cisco's Etherchannel provides 100% load balancing with up to 4 100MB switch ports on a Cisco switch, that's 800mbps. Some NICs even support Etherchannel, such as some Compaq branded NICs.

I'll throw another subject into the mix. What exactly are you trying to accomplish? Depending upon your company's needs, you could use a simple load balancer using layer 3 round robin only, or you could use layer 4 or layer 5-7 load balancing methods dependent upon your needs. What you really need to determine is what direction you would like this technology to take you to (e.g., simple server load balancing ---> distributed (geographical) load balancing). Once you determine that, and what exactly your going to use load balancing for, then you will be able to determine what method you want to use.
