Multiple Nics teamed to share a single ip with SBS 2011

Last Modified: 2016-05-31
Hello experts,

I am building a SBS 2011 box and the client insists that I try to use two nics and team (or bind or whatever is the correct term) to share a single IP address.  He believes that the gigabit pipe coming from the cisco esw 540 48 port switch is a bottleneck and wants to, effectively, create a 2 Gigabit connection.  I read a few articles about this procedure in the past, but could use some help deciding on the configuration that will yield the fastest connection between the server and the 25 clients.  Budget should also be considered between options, but they are willing to spend what it takes to deploy the concept.

This is currently a single server setup design that will run SBS 2011.  There is a single subnet with one primary switch (the cisco esw 540 48port).  There are a couple of small switches in remote offices connected to the primary switch.  Basic Time Warner Cable router/modem connected to the office firewall/router with static IP.

I know that SBS 2011 does not like the server to have multiple IPs due to problems with the configuration and maintenance wizards, so the target is a single IP solution.

I know that SBS 2011 is based on Server 2008 R2 and believe there is a software based solution.

The rest of the server design will be as fast as possible regarding hardware components.

Some options that I do not know much about are using software teaming v hardware, if it is somehow possible to use a 10 Gigabit nic and add some sort of appliance that inputs multiple lines at 1 Gigabit and outputs a 10 gbps line, using a pcie card with two nics on the card instead of trying to use 2 cards (I would hope this option would have a chip to do the integration on the card instead of a software based approach).    I also do not know if there is a configuration option using the cisco switch that will result in a solution.

This question will be considered answered when a solution is presented and justified over any other options.  A link to the solution would be appreciated.  I am not asking anyone to write a report for me, just a few lines on why to choose their option.  I appreciate links to articles and blogs in conjunction with a solution and a couple lines, but I am not a fan of posts that include 5 links and nothing else.  I am asking for your expert advice.

If utilizing 2 nics with one IP is a particularly poor idea for a single server running SBS 2011, a convincing argument for that position will be considered a solution as well.

I personally feel that a 1 gbps line is just fine for this office, but my client is set on trying  this option, so I appreciate any help I can get.

Thank you all in advance... eric
