Review: TP-LINK TL-SG2424 Smart Gigabit Ethernet Switch for Home or Office

August 6, 2015 By Stephen 3 Comments

There comes a time when a cheapie Ethernet switch just won’t cut it. That’s where the TP-LINK TL-SG2424 really shines, bringing the features you need at a price you can afford.

The Terrifying True Story Of Virtual Machine Mobility

December 22, 2011 By Stephen 6 Comments

Virtualization of server, network, and storage services illuminates the link between physical resources and functional applications. A running virtual machine can instantly move from one server, network adapter, HBA, or LUN to another. And when it happens, traditional components have no idea how to react.

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 2018 iPad Pro is a Beast!

The third-generation iPad Pro is a great machine but also a bellwether of change at Apple. It will be very hard for the rest of the mobile and client computing industry to keep up with this kind of progress!

Aerobie AeroPress Review: The Hacker Coffee Maker

February 7, 2011

Computer geeks like me love coffee, the stronger the better. We computer folks are also known for experimentation and a do it yourself ethic. Some of us even love to get outdoors and toss around a flying disc or football. What happens when you mash up all of this? You get the Aerobie AeroPress, the hacker coffeemaker.

Nimble Storage Rolls Out an All-Flash Array

February 24, 2016

It took longer than I expected for Nimble Storage to introduce an all-flash array, but their AF7000 looks to be a very credible offering. They’re targeting XtremIO and Pure with their marketing, but I expect HP, Dell, and especially NetApp to be cross-shopped more frequently. In that fight, I expect the Nimble AF7000 to be very attractive indeed!

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!

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.

Infographic: Real-World Port Throughput Relative To Thunderbolt (Formerly Light Peak)

February 21, 2011

Just how fast is 10 gigabits per second anyway? To help out, I’ve prepared another napkin-tastic infographic!

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!

My Visit to Bletchley Park

August 3, 2012

Bletchley Park is much more than a museum. For those interested in the history of computing, like me, or World War II buffs, it’s a must-see. The reconstructed Bombe and Colossus computer are truly breathtaking, and I find myself drawn to the stories of codebreaking that took place here. I highly recommend a visit!

Why Are PCIe SSDs So Fast?

June 12, 2013

The world of storage can be confusing, with obscure terms hiding massive differences in technology and performance. Such is the case for the latest PCI express SSDs: They are much faster than traditional SAS or SATA SSDs, but many aren’t sure exactly why. In this article, I will try to explain the real difference.
