Storage Virtualization Charlotte: Thoughts and Reactions

October 21, 2008 by Stephen 4 Comments

I’ve just finished my day in Charlotte on my Storage Virtualization Seminar tour for TechTarget. We had another great crowd – everyone seemed interested even if some were shy about speaking up. I was especially pleased to see the optimism about the city’s post-Wachovia future. Comments at the event focused on management, with my concerns […]

The Storage Utilization Waterfall: Raw, Usable, and Used

October 1, 2008 by Stephen 3 Comments

My February 2003 column for Storage magazine focused on the surprising difficulty of measuring storage utilization. I wrote: “A true measurement of utilization would reflect every layer of usage metrics – from raw disk in a shared array to used storage within files. Raw storage for each new frame of reference is contained within […]

3PAR’s Thin Un-Provisioning is Slightly Less Bad

September 2, 2008 by Stephen 13 Comments

3PAR just introduced their third-generation storage hardware, bringing a novel feature to the world of thin provisioning: Hardware-assisted “zero-detection” to convert standard storage to thin provisioning. Although only certain special-case users will benefit from this technology, it’s nice to see someone working on one of the pitfalls of the technology – that it’s really hard […]

SAN School Podcast Series Posted

July 8, 2008 by Stephen Leave a Comment

TechTarget recently uploaded three podcast versions of my SAN School series from Storage Decisions last year. These are audio-only, but I might be able to dig up the accompanying slides. If you’re interested in this, please leave a note below or contact me through email. So without further ado, I present three lessons on SAN […]

Where the SAN Stands

July 7, 2008 by Stephen Leave a Comment

Real Video: Where the SAN Stands Curious about the current state of SAN technology? Stephen Bigelow of TechTarget interviewed me (last summer) about SAN options, and the video is now live on their BitPipe site. Topics covered include combined iSCSI and FC SANs, ups and downs of modular storage and oversubscribed switches, next-generation SAN management […]

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.

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.

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!

How Will Cisco Recover From The Consumer Strategy Blunder?

January 2, 2013

Cisco made a massive strategic blunder in the last decade, aggressively moving into consumer devices rather than focusing on their core enterprise and service provider markets. It seems that Cisco is now in the process of rectifying this mistake, but charting a path to growth is an entirely different matter!

Scaling Storage In Conventional Arrays

November 19, 2013

It is amazing that something as simple-sounding as making an array get bigger can be so complex, yet scaling storage is notoriously difficult. Our storage protocols just werenâ€™t designed with scaling in mind, and they lack the flexibility needed to dynamically address multiple nodes. So my hat is off to these companies and others who have come up with clever ways to maintain compatibility while scaling out beyond the bounds of a single storage array.

It’s Time To Move Beyond Passwords (Especially On Web Sites)

January 8, 2016

Sure, single sign-on puts all your eggs in one basket. But this is vastly preferable to trusting that hundreds of third-party baskets are secure, especially when they prove on a weekly basis that they aren’t! It’s time to put distributed passwords behind us and switch to systems like SAML, both for businesses and consumers.

Cisco’s Trojan Horse

September 15, 2014

Industry watchers like me have long wondered when Cisco will transform itself into a full-line IT infrastructure vendor. This strategy was tipped in 2009 as Cisco barged into the server market with UCS. But one leg of the stool is still missing: Storage remains the province of Cisco partners like EMC and NetApp.

Sony NEX-5 Camera Review

September 15, 2010

The world of photography is like so many others: A vast gulf separates the amateurs and enthusiasts, from equipment to nomenclature to skills. I am decidedly in the amateur camp when it comes to photography, but I recently upgraded to a new compact interchangeable-lense camera, the Sony alpha NEX-5. It is an excellent match for my needs, allowing me to expand my skills and explore more advanced photographic techniques without sacrificing portability and ease of use.

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!
