Recalling An HP MediaSmart Server To Active Duty

July 21, 2017 By Stephen 17 Comments

I was recently given an old HP MediaSmart EX470 server along with some other junk hardware. Although it has no graphics, a slow single-core AMD Sempron CPU, and just 512 MB of RAM, I was able to revive it quite satisfactorily. Here’s how I upgraded the hardware and software.

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

May 25, 2016 By Stephen 3 Comments

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 […]

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 Rack Endgame: Open Compute Project

September 17, 2014

On reading my thoughts about the evolution of enterprise storage, many pointed out that this looks an awful lot like the Facebook-led Open Compute Project (OCP). This is entirely intentional. But OCP is simply one expression of this new architecture, and perhaps not the best one for the enterprise.

Why Big Disk Drives Require Data Integrity Checking

December 19, 2014

Hard disk drives keep getting bigger, meaning capacity just keeps getting cheaper. But storage capacity is like money: The more you have, the more you use. And this growth in capacity means that data is at risk from a very old nemesis: Unrecoverable Read Errors (URE).

How Fast Is It? A Storage Infographic

October 29, 2010

How fast is a hard disk drive? How about the various flavors of SATA and Fibre Channel? Check out this handy Pack Rat infographic to answer the question, “how fast is it?”

What’s (Still) Wrong With Dropbox For Business

April 17, 2013

I am a heavy (and paying) user of Dropbox, using it both for business and personal storage and synchronization. Although I find the service incredibly useful, Dropbox is far from perfect, especially for business users. So I thought I would take a few moments to talk about what I’d like to see Dropbox improve.

Follow the Yellow Brick Road to the Software-Defined Future

November 29, 2012

The Software-Defined Datacenter is a great concept, but it just won’t work. The big enterprise companies will never allow VMware (and daddy EMC) to commoditize them out of existence, so useful implementations will be rarer than ruby slippers. The best we can hope for is point enhancements to enable greater virtual machine mobility through SDN and improved storage integration.

How To Keep Your Family Activities In Sync With A Shared Google Calendar

April 18, 2010

Smartphones, computers, and iPads are proliferating in families today. Although my three kids do not (yet) have their own mobile phones, we still have quite a few devices with calendar functions: An iPhone each for me, my wife, and our au pair along with an iPad and a few computers. Using Google Calendar, we have set up an awesome shared calendar to keep all of our activities in sync. Read on for instructions!

What You See and What You Get When You Follow Me

May 28, 2019

Social media ought to be social, not just a broadcast platform. That’s my feeling at least. It’s been a while since I’ve ranted about “write-only” social media accounts, so I thought I might as well do it again. And at the same time, I thought I would update you on my promise to the people who read, follow, and interact with me online.

Thinking About Storage In a New Way, From Cloud to Flash, with Dropbox and Fusion-io

July 23, 2013

I’ve been a storage revolutionary for quite a while, looking for new ways of data storage rather than technologies that perpetuate the same old approaches. That’s why I’m excited about the implications of two very different API access methods announced by Dropbox at DBX and by Fusion-io today at OSCON.
