NIC Bonding On Slackware 12.1

NIC Bonding On Slackware 12.1

I was standing in front of a problem while I built a NFS Storage Server. It is necessary for me to have redundancy in every point of view. I solved all redundancy issues I had by using server hardware with redundant power supplies, a Raid 1+ 0 Raid array and two UPS’s one for each power supply. The only thing left in my mind was what about a network failure? Well just use the two Gig NIC’s and hook each of them up to its own switch. Great idea but how do I get them acting as one unit speak one single IP? NIC Bonding was my solution. After a couple of hours researching on the Internet stumbled upon the build in solution by using ifenslave.
