How Does OpenFlow Impact The Daily Life Of Networkers?

May 16, 2013 By Stephen 1 Comment

What does OpenFlow mean for networking and networkers? This is far from resolved, and the rise of “software-defined storage” and the greater “software-defined” datacenter movement makes it relevant beyond networking. Are we infrastructure folks to become programmers? Will SDN lead to a shift towards the DevOps mentality? And is any of this really relevant to non-service provider enterprise IT?

Back From the Pile: Interesting Links, February 11, 2011

February 11, 2011 By Stephen 1 Comment

I’ve spent this week in San Jose, CA at Tech Field Day 5, and that’s the bulk of my news. We heard from great companies: Symantec, Drobo, Druva, Xangati, NetEx, InfoBlox, and HP. Whew!

GPS Time Rollover Failures Keep Happening (But They’re Almost Done)

This is week “1111111111” in the GPS system. Tomorrow morning it will roll over to week “0000000000”. How well will various systems handle this change? Not well, judging by what we’ve seen so far!

Ranting and Raving About the 2018 iPad Pro

I remain enthusiastic about the iPad Pro, despite getting a scratched screen and my concerns about durability. It’s a worthy successor to the original and offers enough improvements that I’d recommend the upgrade for just about anyone who uses their iPad for serious work. It’s still not yet a laptop replacement, but this is due more to a lack of desktop-class software for iOS than anything in Apple’s control.

The Four Horsemen of Storage System Performance: The Rule of Spindles

August 25, 2010

Why do some data storage solutions perform better than others? Mechanical performance, RAM caching, I/O capacity, and the intelligence of the system all have a part to play. Today we examine the rule of spindles: Adding more disk spindles is generally more effective than using faster spindles.

Deduplication Coming to Primary Storage

September 16, 2008

Although deduplication of storage is nothing new, with Data Domain and other making hay with the technique for years, it has never been ready for prime time – reduction of active primary storage applications like email and databases. Instead, deduplication has been relegated to second- or third-tier status, deduplicating archives and backup data. But change is in the air, and deduplication vendors are starting to bustle towards the bright lights of primary storage.

Faster Ethernet Gets Weird

June 19, 2015

“One size fits all” doesn’t work for Ethernet, but this proliferation of speed options sounds like trouble without automatic capability negotiation. It’s nice to have options, but the IEEE must remain focused on interoperability and rein in the interests of the various companies proposing next-generation Ethernet technologies.

My 2012 Project: Improving Energy Efficiency

January 3, 2012

I am in the process of upgrading my own home to make it more energy efficient. I do this mainly as an exercise of faith and science, since my electric and gas bills are not currently all that expensive. But I just can’t countenance burning 10 times more electricity than I need to, even if I can afford it. It’s also an exercise in geekiness, since today’s lighting alternatives and appliances have an undeniable techno-cool factor about them.

The iPhone Revolution 10 Years Later

January 9, 2017

10 years ago today, Steve Jobs introduced the iPhone, perhaps the most revolutionary technological product in history. There have been many important products introduced before and since, but nothing else was as groundbreaking as the iPhone. Watching the introduction, it’s amazing to see just how many things were introduced that day that have become integral to daily life today.

How Smart Is the Mondaine Helvetica Smart Watch?

December 30, 2015

I love watches and technology, so I was thrilled to hear about the creation of a “horological smart watch” base by the Swiss watchmaking industry. One of the first examples of this new breed is the just-released Mondaine Helvetica Smart. I purchased one of these watches, the limited-edition “1 of 1957” variety, and have had a chance to evaluate it both as a watch and a gadget.

The Rack Endgame: Converged Infrastructure and Disaggregation

September 19, 2014

As Iâ€™ve written about what Iâ€™m calling the â€œRack Endgameâ€, the specter of converged infrastructure hasnâ€™t been far from my thoughts. As others have pointed out, disaggregation of servers, networks, and storage doesnâ€™t require a rack-sized stack; it can exist in a rack-mountable chassis and is already on sale!

What’s the Difference Between a Jailbroken and an Unlocked Phone?

May 5, 2012

If you’ve traveled much, you’ve probably run across â€œunlockedâ€ mobile phones and devices. If you own an Android or iPhone smart phone, you probably also heard about â€œjailbreakingâ€. It seems like lots of people are confused about these two things, so I decided to write down a quick post explaining them.
