Fibre Channel over IP (FCIP) for CCIE DC

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.

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…)

Fibre Channel (FC) Basics for CCIE DC

When first looking at the blueprint for the CCNA/CCNP/CCIE Data Center track, one of my biggest fears was storage. My entire career thus far has been based on traditional IP data networks, not storage networks. I’m used to things like MAC addresses and IP addresses, not WWPNs and FCIDs. This is a completely foreign technology to most Network Engineers. You have to think back, at some point we were young and hopeful CCNAs-to-be, we knew nothing, but that didn’t stop us! Intimidation is over-rated, so throw fear aside and know that persistence always wins.

So you’ve read all about FC, and now you want to see how to configure it. In this blog post I’ll be going through a basic FC configuration, covering some fundamental Fibre Channel topics along the way, such as:

VSANs
FLOGI
FCNS
Trunking
Zoning (Basic and Enhanced)
FC Aliases
Device Aliases
Domain ID Modification
FSPF (with traffic engineering)
SAN Port-channels
