What’s Jeff Reading? The Clayton M. Christensen Reader

I wanted to learn more about how disruptive technologies affect businesses.  In my search for content on this topic, I came upon the Clayton M. Christensen Reader.  This book is a compilation of many articles that Mr. Christensen has written on the impact of disruptive technologies and his thoughts on how to avoid becoming a “disrupted” business (as in, missing the boat on a disruptive technology).

I appreciate the way Mr. Christensen writes and his “Idea in Brief ” and “Idea in Practice” sections in each article.  They provide a summary of what the author is talking about and a “call to action on how to address it.

NetApp Simulator CDOT 8.2 – Network Configuration

The NetApp Simulator Install & Setup Guide has some pretty vague instructions on how to setup the network for your simulator.  I decided I’d try a few different configurations and see which one work for my needs.  I landed on a fully NAT network vs a hybrid with Host only and Bridged networks.  The main benefit of the NAT network is that I can access all the devices from their host only IP w/o doing anything special (VMware routes the traffic via a Virtual Network Interface).

NetApp Simulator CDOT 8.2 – Recipe: Add SSD & More Disks

I’ve used NetApp 7-Mode simulators in the past.  However, after attending Cluster Mode 8.2 Administration class, I wanted to have some good Cluster Mode simulators to practice on before I took the test.  I’m going to post some recipes for how I “enhanced” my simulators for my study needs.  This particular recipe involves removing the default disks that come with the simulator and adding a shelf of 500MB SSD and 3 shelves of 9GB disks.  This will provide more disks for aggregates at a larger capacity and allow for configuring FlexCache and Hybrid Volumes.
