Recently I was speaking to someone (Mike from New Jersey) at Cisco Live and they were raving about their journey to the Flexpod. They were seeking the best compute, networking and storage yet didn’t want to be boggled down with details when it came to the purchasing process. Converged systems like this are relatively new, and honestly when I was an IT pro; we didn’t have options like that! Not to make me sound old, but when Mike and I were talking about this approach I had a few questions.

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.
