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.

Truth in Storage: The Next Generation – Announcing My 2014 Seminar Series

February 3, 2014 By Stephen Leave a Comment

This year for my Truth in IT seminars, Iâ€™m shifting away from virtualization to focus on enterprise storage once again. But this wonâ€™t be any ordinary â€œstorage 101â€ seminar. Rather than trying to talk about every element, Iâ€™m focused on whatâ€™s new!

Making a Case For (and Against) Software-Defined Storage

January 9, 2014 By Stephen 5 Comments

Everyone is talking about â€œsoftware-definedâ€ everything lately, so it was only a matter of time before industry buzz turned to software-defined storage. VMware and EMC really stoked the flames with a constant barrage of marketing directed in this direction. But how exactly do you software-define storage? And what does this mean?

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.

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.

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.

ZFS Is the Best Filesystem (For Now…)

July 10, 2017

ZFS should have been great, but I kind of hate it: ZFS seems to be trapped in the past, before it was sidelined it as the cool storage project of choice; it’s inflexible; it lacks modern flash integration; and it’s not directly supported by most operating systems. But I put all my valuable data on ZFS because it simply offers the best level of data protection in a small office/home office (SOHO) environment. Here’s why.

vSphere 6: NFS 4.1 Finally Has a Use?

February 3, 2015

Way back in the 1990’s, UNIX admins delighted in upgrading from NFSv2 to NFSv3. Then NFSv4 came around and … crickets. Now VMware has become the first major/useful/mainstream application for NFSv4.1, so the floodgates are open! But are they?

VMware’s Hardware Partner Strategy: Heads I Win, Tales You Lose

February 11, 2013

VMware is in an enviable but tricky situation: The company must work closely with hardware partners, keeping these prime sales and promotional channels happy and supportive. But VMware must also innovate around proprietary OEMs, subverting their products with integrated software before a rival steps up with an integrated alternative.

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!

Sony NEX-7 Hands-On Review Part 1: The New Super-Camera

March 26, 2012

It took over five months, but Sony finally delivered my NEX-7 kit on March 8 (my birthday, natch!). After using the camera for a few weeks, I can say it’s exactly what I hoped it would be: A worthy upgrade over the NEX-5, and perhaps the best enthusiast camera on the market. But it’s not without flaws, including some surprising shortcomings. Here’s my hands-on review!

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.
