Linux NIC teaming recommendations
Introduction In my job as a network engineer, I am constantly looking for ways to increase the availability of the network. This is especially true in the data center, where services are expected to always be available. One of the ways to increase the network availability of a server is by using multiple network interfaces. This technique has many different names, but I am just going to call it NIC teaming. Purpose of NIC Teaming NIC teaming increases network availability by removing single-points-of-failure (SPOF). These SPOFs are components that will cause a service outage if they become unavailable. If we consider a single network connection from your server to your switch, we can identify quite a few SPOFs: Server NIC failure Network cable failure (such as being cut or unplugged) Network switch failure (such as a planned firmware upgrade or unplanned outage) Methods of NIC Teaming The reason I am writing this blog is to help people understand the different options for NIC team...
