How many websites can one Nic handle?

If I plan to have 500 or more websites on my server, would it be better to have them on multiple Nics?

Hi,

there is no real limit for number of IP addresses, other than address space available.

unless you have a specific reason, i would recommend differentiuating the web sites by host header rather than IP address - it is less work to set up and better address space management practice.

the only reason you would need seperate addresses is if you wanted them to all have ssl.

i host several hundred web sites per server, and only use unique addresses if the site needs ssl.

cheers.

I like your answer and possibly might accept it as a good answer still; but I would like to delve into it a little further.
It seems to me you can manage the bandwidth better by seperating websites onto different NICs. Thats what made me think I could seperate maybe 100 websites per NIC, Or as you say maybe 100 host headers per NIC. Does this sound like a good idea or does it really not matter?

As much info as possible please. Thanks.

Hi,

If you start using up 100 megabits with your web sites, you are gonna need more than just an extra NIC to overcome the problem - 100mb is a LOT of load and there wouldn't be many (win2K at least) web servers capable of pumping out that much over a sustained period.

Keep in mind that most of the data is coming off disk, and even if you have a super fast RAID storage, you'll be lucky to peak at 100mbits.

If you need more than that, you'd want to consider multiple servers (cluisters etc) rather than network interfaces.

Also, if you want to start throttling individual sites, you can do it with IIS anyway - see performance tab in web site properties.

One more thing: Consider your internet uplinks - how much data can your network push out all up?  there's no sense in having half a gig of bandwidth to your LAN when your uplink is only 100megs.

Cheers.
