OpenStack and Storage, a Response

No Fibre Channel allowed?

No Fibre Channel allowed?

During the recent OpenStack Summit in Atlanta, GA, I wrote a blog on the Cisco blog site called “Thoughts on #OpenStack and Software-Defined Storage,” arguing for the need to avoid reinventing the wheel when it comes to Software-Defined X and storage. My very good friend Stephen Foskett wrote a (fair and excellent) response, entitled Why OpenStack Doesn’t Need Fibre Channel Support.

Stephen’s argument, essentially, is that Fibre Channel, and the conventional IT that it represents, do not really have a place in the Open systems, such as the OpenStack ecosystem. Thing is, I think Stephen’s argument is a little too late. The cat has left the barn, and the genie has been let out of the toothpaste tube, the train has left the gate. Or something to that effect.

FCoE vs. iSCSI: The Cagefight! – Flexibility

March 30, 2010 8 comments

This is the second in a series of posts designed to address some of the questions I’ve posed with respect to FCoE vs. iSCSI, in an attempt to take a detached view towards the pros and cons of each technology as it relates to measuring up in the data center. In this post, we will examine the question of whether iSCSI can provide the same type of traffic flexibility that FCoE can, for the same level of service. Read more…

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…

Gartner on FCoE. Whoa There, Sparky

March 19, 2010 23 comments

I’m too cheap to shell out the $195 (that’s $20/page!) for the latest Gartner report on FCoE, but there have been enough reports on the report that it’s not difficult to see the gist is consistent with Gartner’s long-running hate-affair with the nascent technology. I’m the first to admit that FCoE isn’t a panacea for the data center’s myriad array of issues, but Gartner seems to be far too willing to play the convenient role of grumpy old man and needs to be placed into some perspective.

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…

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…
