Virtualized and Distributed Storage: This Time For Sure!

September 2, 2014 by Stephen 3 Comments

We were never able to achieve storage virtualization in mainstream enterprise IT because we lacked the ability to identify and move data non-disruptively. This has been solved by caching and distributed storage solutions, and it’s only a matter of time before the legacy need for centralized storage falls away.

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.

Storage Changes in VMware vSphere 5

July 16, 2011 by Stephen Leave a Comment

Once again, VMware added a ton of new storage enhancements to vSphere. With storage rapidly becoming the limiting factor in scalability and performance of virtual machine environments, this is no surprise. Also not surprising is the fact that major features like Policy-Driven Storage and Storage DRS (along with SIOC) are exclusive to “Enterprise Plus” licenses.

Changes in Technology Drive Changes in IT Organizations and Roles

April 24, 2011 by Stephen Leave a Comment

Lots of my IT infrastructure management clients are talking about how the advent of Ethernet/IP and virtualization is changing the roles of storage, server, and network administrators. The evolution of the storage role in particular in enterprise IT organizations has been a topic of particular interest to me for a while: I definitely remember thinking about […]

Granularity: The Hidden Challenge of Storage Management

April 19, 2011 by Stephen 2 Comments

Many storage challenges focus on the conflict between data management, which demands an ever-smaller unit of management, and storage management, which benefits most from consolidation. Developing data management capability that is both granular enough for applications and scalable enough for storage is one key to the future of storage.

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.

On the Death of Innovation, or “These Kids These Days!”

May 21, 2012

An obnoxious meme has returned to the fore lately, claiming that innovation is dead. The hippies did it, or maybe it was the Internet, or even a decline of America. But nothing could be further from the truth, and statements like this make me question the perspective of the speaker.

Scaling Storage Is Hard To Do

June 4, 2013

Data storage isn’t as easy as it sounds, especially at enterprise or cloud scale. It’s simple enough to read and write a bit of data, but much harder to build a system that scales to store petabytes. That’s why I’m keenly focused on a new wave of storage systems built from the ground up for scaling!

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.

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.

From Kipling’s Dirigibles to the Jet Age

May 13, 2012

I don’t get much chance to read for pleasure, but two things I’ve been reading recently spurred my imagination. After reliving the advent of modern transportation in the solid non-fiction Jet Age by Sam Howe Verhovek, I stumbled upon two pieces of speculative fiction from an unlikely source that predated everything presented there.

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!

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.

Introducing Rabbit: I Bought a Cloud!

September 10, 2020

We live in a world of cattle, not pets, and Kubernetes rules the roost. I’ve been meaning to spend some time getting up to speed on the latest but didn’t have enough hardware to make that happen until now. I recently bought a whole pile of surplus hardware so I will be able to experiment with orchestration and container platforms in the office.
