The I/O Blender Part 1: Ye Olde Storage I/O Path

May 23, 2012 By Stephen 2 Comments

This old-fashioned, predictable storage I/O path was deterministic and decipherable: The server, the switch, and the array all had enough information to do their jobs effectively and efficiently.

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.

Fasting to Mitigate Jet Lag: Surprise! It Works!

February 11, 2013

I’m a frequent traveler, and thus a frequently suffer from moderate jet lag. It’s just so hard to adjust to a new time zone! But I recently stumbled on a simple method many claim helps your internal clock re-calibrate to travel. After trying it out on my trip to Australia last week, I’m convinced it can help!

Are You a Hypervisor Hugger or a Storage Stalwart?

November 14, 2011

The time has come to take sides on the core question of storage for virtual servers: Do you want storage intelligence to live in the hypervisor or the array? Most administrators are already lining up on one side or the other, unintentionally casting their vote while the rest flounder. But the storage industry must wake up and embrace the divide.

Put that camera away and enjoy the view!

April 11, 2012

Photography is an act of observation and contemplation as much as a technical process. Although cameras, lenses, and (ugh!) flashes can seem cumbersome and intrusive, I ask for patience. I promise itâ€™s not getting in the way of life like some entertainment device. My camera enhances my experience of the world!

The 2018 iPad Pro is a Beast!

November 9, 2018

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!

Why Buy a NEX-7? Why Sony NEX At All?

October 17, 2011

Your tweets about your NEX have intrigued me a bit…I get tired of lugging my Nikon D90 around with my kids, yet I find the quality of most point-and-shoot cameras terrible…so the NEX seems like an interesting compromise.

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!

A Complete List of VMware VAAI Primitives

November 10, 2011

VMwareâ€™s introduced the â€œvStorage APIs for Array Integrationâ€ (VAAI) in vSphere 4.1, and block-heads like me went nuts. Weâ€™ve been trying to integrate storage and servers for decades, and VMwareâ€™s APIs finally allowed this to work in truly seamless fashion. But the world of VAAI is a thicket of bizarre naming and puzzling functionality. Some VAAI primitives are ignored or even hidden! Letâ€™s take a look at the complete list.
