Over the past couple of years the conversation about Fibre Channel over Ethernet (FCoE) and converged networks (e.g., Unified Fabric) has become more and more sophisticated. While I still get the occasional “what is FCoE?” question, and still have to correct the occasional journalist who insists FCoE runs over TCP/IP (it doesn’t!), those conversations are becoming more rare.
Instead, the conversation has shifted from the “what is this?” to “how do I do it?” All the diagrams and napkins in the world can’t predict or prepare for the wide-ranging possibilities that customers have in their data centers. I’ve written about a few of the surprises before (http://blogs.cisco.com/datacenter/ciscolive-2012-and-the-fcoe-surge/) but every day I get more unique (and more interesting) scenarios. Read More »

Outside of that large, black, monolithic machine in the middle of the datacenter referred to as the mainframe, there aren’t that many servers that require as many network and storage connections as the backup server. It’s not really sexy, it’s not computing Pi, generally doesn’t run a hypervisor and is bought with one goal in mind, move data. Not just some data, but a lot. These machines often move all of the data in your datacenter off of disk and onto tape, either real or virtual. In many datacenters, these backup servers are sometimes the only non-x86 platforms left due to their ability to contain high numbers of HBAs for SAN connectivity and NICs for network connectivity. They’re like the tractors of the datacenter. Read More »

Before I came to Cisco I still wrote about Fibre Channel over Ethernet (FCoE) and did my best to try to help edumificate people on how the technology works. One of the most popular things I’ve ever written, in fact, was a comparison between FCoE and another convergence technology, iSCSI. Since that time I’ve come to learn and understand a lot more about both technologies, how they relate to each other, and how storage networks are designed and implemented using them.
Since Demartek published the recent piece on multiprotocol connectivity, which included some comparisons on the protocols regarding latency I thought it might be a good time to revisit some of those questions. Read More »

There are a lot of questions that people ask regarding Fibre Channel over Ethernet (FCoE), especially Multihop FCoE, and what happens when you put it into place inside the Data Center. For the most part, the questions have involved two particular threads: architecture and performance:
- What are my options with FCoE?
- Where can FCoE fit into my Data Center?
- Is there a performance penalty for running FCoE?
- How do Fibre Channel, FCoE, and iSCSI compare?
Demartek, a third-party research and analysis corporation, recently published an evaluation on Cisco’s Multiprotocol Connectivity and Multi-Topology solutions, which found that not only were the topology configurations extremely flexible for many different types of environments, but also found that even with multiple switches, multihop FCoE topologies can provide excellent performance within the Data Center.
Dennis Martin, founder and President of Demartek, will be presenting these findings and discussing his impressions of the technology in a live, public webinar, Thursday, August 9, at 1 p.m. ET/10 a.m. PT. We encourage you to attend to learn more about how these different technologies can fit inside the data center.

As the Product Manager for Fibre Channel over Ethernet (FCoE), I often get asked some of the hard questions about how the technology works. Sometimes I get asked the easy questions. Sometimes -- like two nights ago -- I get asked if the standards for FCoE are done.
I’m not kidding.
My own expectations for discussing FCoE were focused around the topics and conversations that we’ve been seeing over the last year, since the last Cisco Live in 2011. Read More »
