Turn Off Error Recovery in RAID Drives: TLER, ERC, and CCTL

May 30, 2017 By Stephen 4 Comments

Hard disk drives encounter errors from time to time, so it’s a good thing that most have the ability to recover data anyway. But RAID systems usually have their own error recovery capabilities and can be thrown off when a hard disk pauses I/O. So it’s a good idea to use hard disk drives that allow you to disable or limit error recovery in RAID systems.

Storage Changes in VMware vSphere 5.1

September 4, 2012 By Stephen 6 Comments

As I have done since version 3.5, I’m charting the storage changes in VMware’s latest release of vSphere, 5.1. Unlike version 5, which included many new technical storage features, 5.1 mainly tweaks existing features and adds these new elements to the mix.

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!

Free as in Coffee – Thoughts on the State of OpenStack

May 2, 2016

Last week I headed to Austin, Texas to attend the semi-annual OpenStack Summit there. Along with the usual socializing, I was looking to understand the current state of the technology: What does OpenStack really mean these days, and where is it going? Let’s start with “free”. As “the Internet” is quick to point out, this critical word has multiple […]

Not All 802.11n Networks Are Alike

July 2, 2011

Buyers of 802.11n wireless network equipment should not assume they will see a great benefit right out of the box. Most will have to enable by hand a high-performance configuration including wide channels and 5 GHz operation. And some client devices may never reach the levels of performance expected by consumers due to hardware limitations.

A High-Tech Water Heater? Yep! Introducing the A. O. Smith Vertex

November 15, 2012

I justify spending six times more on the Vertex 100 for a simple reason: It’ll keep up with the heavy water use in my house. I’m hoping I’ll never have to worry about hot water as long as I live here. The fact that it saves over $100 per year due to energy-efficient design is just icing on the cake.

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?

Frequent Flier Kung Fu for Novices

March 12, 2012

If you’re careful, even an infrequent flyer can rack up valuable points and maybe even elite status. But don’t do anything foolish, and don’t be fooled by the promises of first-class treatment. Even top-tier frequent flyers sit in coach most of the time!

Donate Your Swag to School Kids In Need

July 28, 2010

Trade shows are a veritable swag-fest, some with great loot and some with junk. I’ve been critical of the booth babe and chotchkie phenomenon, but my friend Kevin Houston has a better suggestion: Donate your (useful) swag like backpacks and pens to school kids in need.

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.

What More Could Alan Turing Have Accomplished?

October 7, 2012

Many of you have probably heard the name of Alan Turing, but most of those probably don’t appreciate the extent of his contributions. To say that he invented the modern world is an overstatement, but he did dream up the computers we see around us today, and helped win World War II in the process. But the story of Alan Turing is as much about exclusion and defeat as it is of genius.
