Reality Check: The FCoE Forecast

October 19, 2008 by Stephen Leave a Comment

This is part of an ongoing series of longer articles I will be posting every Sunday as part of an experiment in offering more in-depth content. There has been a lot of discussion in the storage industry about Fibre Channel over Ethernet (FCoE), making it the toast of Storage Networking World, but this technology remains relatively unknown […]

A Consultant’s View Of The Enterprise Storage Market

September 21, 2008 by Stephen 2 Comments

This is part of an ongoing series of longer articles I will be posting every Sunday as part of an experiment in offering more in-depth content. I am not the typical enterprise storage user. In fact, I am not an enterprise storage user at all – I am a consultant focused for over a decade […]

QLogic and Emulex Deliver 8 Gb Fibre Channel For VMware ESX

July 30, 2008 by Stephen 1 Comment

As I mentioned on Monday, VMware’s Update 2 for ESX 3.5 includes support for 8 Gb Fibre Channel HBAs. This is an important development, so I went looking through the official ESX I/O Compatibility Guide to see which HBAs in particular were supported, but none were listed. This was pretty puzzling, but Rich from VM […]

Storage Fixes in VMware ESX Server 3.5 Update 2

July 28, 2008 by Stephen 5 Comments

VMware just released Update 2 for VMware ESX Server 3.5 (Virtual Infrastructure), and it includes some storage fixes of note: Support for Volume Shadow Copy Service (VSS) for filesystems Windows Server 2003 and Windows Server 2008 guests. This means VMware services like VCB and SRM can now signal Windows Server to quiesce filesystems before creating a […]

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.

Regarding My Symbolic Links and Good Reads

April 16, 2015

I’ve been told that my shares drive traffic to the blogs I read. I’m thrilled that I can share great writing with you in this way, and I hope you find it valuable! But just in case you don’t, I hope you’ll take advantage of the fact that I filter these posts for you into “Symbolic Links” and “Good Reads” so you’ll find it easier to ignore them.

What More Could Alan Turing Have Accomplished?

October 7, 2012

Many of you have probably heard the name of Alan Turing, but most of those probably don’t appreciate the extent of his contributions. To say that he invented the modern world is an overstatement, but he did dream up the computers we see around us today, and helped win World War II in the process. But the story of Alan Turing is as much about exclusion and defeat as it is of genius.

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?

Rocking Out With the Topping VX1 Desktop/Bookshelf Amplifier

October 6, 2015

A few months back, I asked folks on Twitter and LinkedIn for recommendations for a desktop amplifier for a pair of bookshelf speakers. I ended up with a Topping VX1, one of the many “Class-T” digital amps lauded by audiophiles for their excellent sound reproduction. Boy am I impressed! It’s rare that such an inexpensive gadget (around $100!) delivers so much performance!

Hands-On Review: Unicomp Spacesaver M Keyboard for Mac

July 3, 2012

I would not hesitate to recommend the Unicomp Spacesaver M to Macintosh users used to an original IBM Model M, and I am admittedly a tough customer. I wish that Unicomp would update their website, packaging, logo, and keyboard graphics, but none of this really matters as your fingers press the keys. If any keyboard is worth $100, it is the Unicomp Spacesaver M!

Free as in Coffee – Thoughts on the State of OpenStack

May 2, 2016

Last week I headed to Austin, Texas to attend the semi-annual OpenStack Summit there. Along with the usual socializing, I was looking to understand the current state of the technology: What does OpenStack really mean these days, and where is it going? Let’s start with “free”. As “the Internet” is quick to point out, this critical word has multiple […]

Why Big Disk Drives Require Data Integrity Checking

December 19, 2014

Hard disk drives keep getting bigger, meaning capacity just keeps getting cheaper. But storage capacity is like money: The more you have, the more you use. And this growth in capacity means that data is at risk from a very old nemesis: Unrecoverable Read Errors (URE).

The Ideal pfSense Platform: Netgate RCC-VE 2440

September 21, 2015

After some frustration with stability and latency connecting my virtual pfSense router to my cable and DSL modems, I decided to switch to a physical box. I selected the Netgate RCC-VE 2440 as my hardware platform, since it’s the same box that pfSense themselves use as their OEM bundle. It also checks all the boxes with a dual-core Atom CPU, four Gigabit Ethernet ports, and low-power fanless design. Here’s my first impression and installation notes!
