Nate,
Thanks for you input. 802.3ad seems better but I am not in a position to terminate both links in the same switch or same stack. What about mode 6?
Thanks Paras.

You really should go the 802.3ad route (mode=4) if anything, this does require switch support. You can get unpredictable results with mode=0, and if you want best performance and availability stick to 802.3ad, which does require going to the same switch(or stack of switches).
Myself with bonding on linux I use only mode=1.
Another user like yourself posted on this topic a few months ago asking the same kind of question, and went down the non-802.3ad route and had major issues.
Also note that your single-stream performance will not exceed that of a single link between hosts. So if your doing a file transfer between two hosts for example and you have several 1GbE links between them the throughput of that transfer will not exceed 1Gbps. Load balancing is done on a per MAC/IP/tcp port basis depending on the equipment in use.
10GbE is really cheap these days(cheaper than 1GbE in some cases on a per Gb basis) if you need faster performance, and simple to configure, I wrote a blog on this a couple of months ago:
