FCoE vs. iSCSI: The Cagefight! – Performance

March 24, 2010 19 comments

In a previous post, I posed a series of questions with respect to understanding the nature of FCoE and iSCSI marketplaces. In this post I’m going to address one of those questions:

Is iSCSI fast enough at 10GbE, 40GbE, and 100GbE – even with overhead concerns, to rival the performance and efficiency of FCoE?

[2012.08.09 Update: This has finally been tested and I’ve written an update about the performance of the two protocols on my Cisco Blog] Read more…

Re-Examining FCoE and iSCSI Pros and Cons

February 5, 2010 10 comments

It should be obvious that I’ve been doing a lot of thinking about FCoE over the past 2 years, despite only blogging about it for a couple of months (hey, I’ve been busy!). But someone brought up something recently that makes me second-guess the role that FCoCEE will play in the marketplace in comparison to, say, iSCSI. In particular, with vendors now offering 1 Million IOPS in their NICs, is there enough of an advantage performance-wise? Read more…

Modified FCoE Adoption Curve

So, David Vellante created an excellent FCoE adoption curve posted on Wikibon today. When the conversation about “how quickly” or “how much” is applied to FCoE, whether it be hype, fact, or perception, I believe that David’s curve is an excellent broad based timeline that can be seen as a great metaphor. However, I think there is a major shift in the curve’s shape that should be included. Sadly, that shape is a slight downturn before we hit the full upswing.

Moving to FCoE

January 13, 2010 Leave a comment

The appeal of an all-FCoE data center is obvious. Reduce complexity in the data center, reduce the physical assets, reduce the operating expenses (huge power savings potential), very little learning curve, familiar tools. Pretty soon it starts sounding like a no-brainer. But that isn’t the end of the story; it’s just the beginning.

FCoE, iSCSI, and InfinBand – Oh My!

December 23, 2009 1 comment

Over at Etherealmind, Greg Ferro wrote a couple of pieces on FCoE that beg to be responded to. Obviously Mr. Ferro understands a great deal about the storage world, but when it comes to FCoE there are some points that I must disagree with. Read more…
