In part one of this series we covered the internals of HDDs, in part two we went over the internals of SSD, In part three we continue reviewing storage concepts to refresh or learn the right lingo.
Lets start by understanding “Redundant Array of Independent Disks” (RAID). There are RAID levels like RAID0 and RAID1 that are easily to understand and others like RAID5 and RAID6, which many sysadmins misunderstand.

I am a consultant at a Cisco partner and I get to see a lot of different networks. Most of the networks are Cisco, but there are a few that are not. From time to time, I get network assessment projects. I love these types of projects as they are an exploration of uncharted networks to see what can be discovered. Personally I like to have my network consistent, orderly, and precise. The common components of the configurations on all device should be identical. These network assessments usually do not conform to these standards. Syslog configured on some devices pointing to a device that no longer Read More »

“Give me the best servers you have”, they said.
“Give me the best computers you have”, they said.
“Give me more mobile devices”, they said.
“Give me the network required to use all these things”, they (almost) never said.
The enterprise network is still very much considered to be just that hole in the wall next to the electricity outlet. It used to be that you came to work and moved the mouse to wake the computer. Later you plugged your laptop into that other weird looking jack labeled Read More »

As a writer for the IT media, conference speaker, and co-host of the Packet Pushers podcast, I cover emerging networking technologies often. The new tech that comes across my screen ranges in value from “I can’t believe that got funded,” to “Why has no one thought of this before?” and everything in between. As a big idea, software defined networking (SDN) seems to generate about that same range of responses from network engineers. Some networkers think that SDN is an extraordinary technology that’s going to change the world of IT. Others see SDN as yet another in a long string of quirky networking ideas that never gained acceptance. In fact, as I’ve read responses to my SDN-related content over the last few years, I believe that more folks are in that latter camp. SDN is a fad. SDN is a buzzword. SDN will go nowhere useful. SDN will eventually fail to have a universal impact.
I understand the cynicism. After all, for a long time, networking had lapsed in an innovation coma, with nothing especially exciting coming along to really shake things up. Yes, Ethernet’s gotten faster. And that BYOD thing got everyone excited a couple of years ago. But for the most part, we design, build, and operate networks the same way today that we did fifteen or more years ago. The core underlying protocols have grown up or had new knobs and levers added, but generally speaking, if a networker of the past fell out of a time warp and into a design project today, it wouldn’t take them too terribly long to catch up.

All right I confess I’m not that kind of geek. I admire and work with many IT engineers, but if you need me to configure a Nexus switch you’ll be out of luck. I am a geek though, and I know about building successful B2B and B2C Ambassador Programs.
Before I start sharing my 2 cents, let’s take a look at what I mean by Ambassador Programs. Below are three major types. This is a simplified scenario but these large buckets help clarify.
Ambassador Program Types
1. Cast of Thousands: this type of program focuses on amplifying large volumes of content externally. Membership is open to anyone who registers, and includes automated content delivery, gamification, and tracking, where participants are rewarded for their actions in real time. Actions include low-hurdle social media tasks like sharing existing content to social media networks, rating a product, or entering a contest, but can also offer more challenging projects like writing a review, helping users solve problems, and communicating with potential customers. Ideally, ambassadors’ actions are integrated with a CRM platform in order to track ROI. Top participants are identified and nurtured, and in some cases transitioned into the second type of program (below). Read More »
