Veritas Volume Manager

Is Storage the Killer App for Software-Defined Networking?

April 15, 2014 By Stephen 2 Comments

Software Defined Networking (SDN) has always looked a bit like a solution in search of a problem, at least in the enterprise data center. But there are lots of potential applications that need a dynamic and scalable network. In my mind, storage is chief among these, since scalability and flexibility has always been extremely difficult to achieve.

Mac OS X Lion Adds CoreStorage, a Volume Manager (Finally!)

August 4, 2011 By Stephen 16 Comments

Mac OS X was majorly deficient in that it lacked a volume manager. This wouldn’t seem like a big deal to the average user, but held back the operating system in so many ways. A volume manager brings storage virtualization to an operating system, allowing storage capacity efficiently to be managed and manipulated. But all this has changed in Mac OS X 10.7 â€œLionâ€ with CoreStorage.

The Bridge: Veritas Thin (Provisioning) API

January 6, 2011 By Stephen 1 Comment

Thin provisioning needs communication to function, and zero page reclaim is only the array side of the story. WRITE_SAME helps reduce I/O load, but the server needs to use it. Wouldn’t it be nice if the operating system, file system, or volume manager would use these commands to help recover capacity?

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.

Edward Snowden Is Right: We Must Protect The Internet

March 19, 2014

Edward Snowden, NSA whistleblower, appeared at TED2014. His video, embedded below, must be watched. You may think he’s a hero or you may think he’s a villain, but he’s unequivocally right about one thing: We must protect the integrity of the Internet and online communications or we risk disrupting the world economy and all of our lives.

Storage Changes in VMware vSphere 5

July 16, 2011

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.

It’s Time To Speak Out Against Sexism In IT Recruiting

May 6, 2013

I have waged a long-standing battle against the sexist and offensive use of scantily-clad, non-technical “models” at technical trade shows. Sometimes known as “booth babes”, the use of women in this way harms our entire industry and makes companies look stupid, to boot. But when a recruiting firm uses such offensive tactics, it does even more harm, verging on illegal!

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!

The iPhone Revolution 10 Years Later

January 9, 2017

10 years ago today, Steve Jobs introduced the iPhone, perhaps the most revolutionary technological product in history. There have been many important products introduced before and since, but nothing else was as groundbreaking as the iPhone. Watching the introduction, it’s amazing to see just how many things were introduced that day that have become integral to daily life today.

Ten Terrible Apple Products

June 14, 2012

I’m often accused of being an Apple fanboy. While it’s true that I love my vast selection of fruity products from Cupertino, I’m not blind when the company makes mistakes. In fact, I think Apple’s mistakes are as enlightening as their successes: They reveal a company that is fallible, sometimes learning but often allowing the junk to rot far longer than other companies would.

Microsoft’s Big Chance to Change

August 23, 2013

It takes a truly-remarkable leader to be willing to kill his old golden geese to make room for a new one; so far, only Apple and Amazon seem willing to forgo continuity in the name of profitable destruction. But new corporate leadership at Microsoft might un-stick the company and awaken the once-innovative Redmond powerhouse. The retirement of Steve Ballmer is welcome news.

Sony QX100 Lens Camera: Ruined by a Flaky iOS App

October 7, 2013

I was thrilled by the possibilities of adding a professional-quality camera sensor and lens to my iPhone, so I immediately pre-ordered Sony’s DSC-QX100 “lens camera”. It held so much promise, not just as a real innovation but also as a major productivity tool. That’s why I’m angry to write this, a scathing review of the horrid software that ruins the QX10 and QX100 experience. Do not buy this device.
