Fibre Channel over IP (FCIP) is a tunneling protocol used to connect FC networks across IP networks, such as a WAN. It uses TCP with the DF bit set. Being that this is IP storage, it is only supported on the MDS platform. The basic configuration is straight forward, but be aware that there are lots of configurable tweaks. In this blog post I’ll be going through the configuration of several FCIP topologies, feel free to follow along. At the end I’ll post a quick template.
Reference (This document is quite excellent):
Below is the topology we’re looking at. We have a server in Data Center 1 that needs to attach to JBOD storage in Data Center 2 over the IP network.
To accomplish this, we’ll create an FCIP tunnel between MDS1 in Data Center 1 and MDS2 in Data Center 2. (more…)
