Cisco Live US, San Diego CA

June 2, 2012 By Stephen Leave a Comment

Next week I’m off to San Diego for Cisco Live US 2012. My previous experience with Cisco Live was definitely positive: It’s a whole world of networking fanatics and lots of ecosystem companies. Plus, last year included an amazing party hosted by yours truly (in disguise!)

Sony 55-210 OSS Tele-Zoom Lens: Hands-On Review

February 15, 2012 By Stephen 1 Comment

Although certainly not the fastest lens (optically or workflow-wise) the SEL55210 is a screaming bargain at $399. The lens is light and compact enough to bring along â€œjust in caseâ€, something that can’t be said of many, SLR tele-zoom lenses. Once it finally focuses, image quality is excellent and the built-in Optical SteadyShot makes it usable even in low light conditions.

Two Online Events You Should Attend (And Two More That You Can’t)

December 6, 2011 By Stephen 1 Comment

I’ve been quite busy lately recording webinars, writing articles, and setting up speaking events. This week, I’m in Boston and New York for private speaking engagements. I’ll also be recording a webinar with an exciting new storage/virtualization company, Nutanix, and I urge you to tune in to that one!

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.

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.

Defining Failure: What Is MTTR, MTTF, and MTBF?

July 6, 2011

Most computer industry vendors use the term â€œMTBFâ€ rather indiscriminately. But IT pros know that systems do not magically repair themselves, at least not yet, so MTTR and MTTF are just as important!

The Fat Middle: Today’s Enterprise Storage Array

August 31, 2014

Ask any project manager if it’s possible to deliver something that is fast, good, and cheap, and they’ll laugh. The phenomenon known as the Iron Triangle limits just about everything in the world from meeting all three conflicting requirements. Yet, for the last two decades, enterprise storage array vendors have been trying to deliver just this. How’s that working out?

Scaling Storage In Conventional Arrays

November 19, 2013

It is amazing that something as simple-sounding as making an array get bigger can be so complex, yet scaling storage is notoriously difficult. Our storage protocols just werenâ€™t designed with scaling in mind, and they lack the flexibility needed to dynamically address multiple nodes. So my hat is off to these companies and others who have come up with clever ways to maintain compatibility while scaling out beyond the bounds of a single storage array.

Scaling Storage At The Client

November 25, 2013

Scaling storage is a serious challenge for the industry, but there is a great deal of thought, effort, and creativity going into it right now. Companies like Gridstore, Oxygen Cloud, and Cleversafe have come up with effective client-side solutions to enable scale-out storage to sing. If you’ve got an appropriate application, client, or gateway, scale-out is a real possibility!

Here’s Something Your Raspberry Pi Can’t Do: Gigabit Ethernet and SATA in the Olimex A20-OLinuXIno-LIME2

May 25, 2016

I’ve really enjoyed experimenting with the Raspberry Pi, and have even deployed a few as UNIX servers in my home and office network. The quad-core performance of the latest Pi models is awesome, but serious I/O limitations remain. With just one USB 2.0 interface shared for all network and storage operations, you aren’t going to […]

Datacenter History: Through the Ages in Lego

October 22, 2013

Readers of my blog know that I love computer history. Therefore, I decided to focus my entry in Juniper Networks’ “Build the Best (Lego) Data Center” contest on the history of computing. Specifically, I would re-create key historic machines to contrast them with a modern view.

What’s the Deal with Containers?

October 21, 2016

Lately, it seems like everyone just can’t stop talking about containers. But I’m sensing a distinct lack of real understanding of the technology from many people, not to mention lots of confusion about what containers really mean for today’s datacenter folks. So I set about learning more and figuring out for myself what the deal is with containers. Here’s where I’m at.
