Brocade’s Flawed FCoE “Study”

Wed, 05 Feb 2014 23:45:04 +0000

Disclosures I do not work for Cisco, Brocade, or any of the companies mentioned here. I do work for a reseller that sells some of these products, but this post (as are all posts on this site) is my opinion only, and does not necessarily reflect the views of my employer or any of the … Continue reading Brocade’s Flawed FCoE “Study”

…everything looks like a nail. Surely everyone has heard this saying, as a way of suggesting that one’s sphere of knowledge is perhaps limited. Indulge me for a moment in an example from my own past. It was the early nineties and I was working on my truck, a 1982 Datsun 4×4 pickup. I had … Continue reading When your only tool is a hammer…



Dave’s Pet Peeves

Sat, 26 Jan 2013 23:18:00 +0000

This post could also be named “Why market share doesn’t matter”, “Why I don’t care what now-standard ideas you invented”, or “What have you done for me lately?” In my career, like most of you, I have sat through too many product presentations, marketing pitches, and technical demos to count. I have talked to countless … Continue reading Dave’s Pet Peeves

Request for help! NetApp gurus, please chime in!

Thu, 19 Apr 2012 20:06:25 +0000

Haven’t used my blog for this purpose before, but figured it couldn’t hurt to give it a shot! I’m not going to have an opportunity to test this until next week, so I’m hoping to get some feedback about whether or not I’m attempting the impossible. I’m trying to see if I can multiple sub-interfaces … Continue reading Request for help! NetApp gurus, please chime in!



Firefly Communications named Cisco 2012 Global Learning Partner of the Year!

Thu, 19 Apr 2012 16:54:32 +0000

I’ve thus far refrained from posting anything remotely sales-y or promoting my company, but I’m very proud of this group accomplishment and wanted to share.

This wasn’t intended to be a detailed analysis, just a couple of random musings.   Comments as always are welcome. —– While NFS and iSCSI … Continue reading FCoE vs. iSCSI vs. NFS
