Faster Ethernet Gets Weird

June 19, 2015 By Stephen 6 Comments

“One size fits all” doesn’t work for Ethernet, but this proliferation of speed options sounds like trouble without automatic capability negotiation. It’s nice to have options, but the IEEE must remain focused on interoperability and rein in the interests of the various companies proposing next-generation Ethernet technologies.

Interop NYC and The Great Debate: ISCSI Beats Fibre Channel

October 3, 2011 By Stephen 4 Comments

The battle lines are drawn between 8 Gb Fibre Channel and 1 Gb or 10 Gb iSCSI and NFS. This is the baseline for my Interop debate. I am not arguing about the future of SAN, or even iSCSI versus NFS. Rather, I am arguing that most businesses would be best served by implementing an iSCSI SAN rather than purchasing Fibre Channel today.

FCoE vs. iSCSI – Making the Choice

May 20, 2011 By Stephen 18 Comments

iSCSI is an excellent choice in situations where Fibre Channel investment is nonexistent or badly in need of wholesale upgrade. FCoE, on the other hand, is likely to take over in high-end enterprise shops. It is relentlessly promoted by major vendors, and it seems that they will force the upgrade eventually.

Which Small Enterprise Storage Arrays Are Worth Considering?

April 8, 2011 By Stephen 1 Comment

It’s never been a better time to be in the market for enterprise storage products, with many excellent options available at affordable prices. But the market can be confusing for the uninitiated, with a variety of network options and capabilities. Even those of us “in the know” about enterprise storage are sometimes surprised by the offerings and companies in this space! So when Jerome Wendt from DCIG approached me to collect data for a market overview and buyer’s guide, I was excited. It was my big chance to really get to know these products!

Infographic: Real-World Port Throughput Relative To Thunderbolt (Formerly Light Peak)

February 21, 2011 By Stephen 2 Comments

Just how fast is 10 gigabits per second anyway? To help out, I’ve prepared another napkin-tastic infographic!

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.

Datacenter History: Through the Ages in Lego

October 22, 2013

Readers of my blog know that I love computer history. Therefore, I decided to focus my entry in Juniper Networks’ “Build the Best (Lego) Data Center” contest on the history of computing. Specifically, I would re-create key historic machines to contrast them with a modern view.

The Rack Endgame: A New Storage Architecture For the Data Center

September 3, 2014

Top-of-rack flash and bottom-of-rack disk makes a ton of sense in a world of virtualized, distributed storage. It fits with enterprise paradigms yet delivers real architectural change that could “move the needle” in a way that no centralized shared storage system ever will. SAN and NAS aren’t going away immediately, but this new storage architecture will be an attractive next-generation direction!

Replacing Google Reader With Feedbin and Reeder

May 5, 2013

I am an avid Google Reader user, so I’m thoroughly annoyed by Google’s decision to kill it as of July 1. But there’s no stopping the tide, so I’ve made the move to Feedbin as a Reader replacement as of today. It’s a slick, snappy web application with a committed developer and, critically, support for Reeder, my favorite offline RSS reading application. Let’s hope this works!

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!

Frequent Flier Kung Fu for Novices

March 12, 2012

If you’re careful, even an infrequent flyer can rack up valuable points and maybe even elite status. But don’t do anything foolish, and don’t be fooled by the promises of first-class treatment. Even top-tier frequent flyers sit in coach most of the time!

The Terrifying True Story Of Virtual Machine Mobility

December 22, 2011

Virtualization of server, network, and storage services illuminates the link between physical resources and functional applications. A running virtual machine can instantly move from one server, network adapter, HBA, or LUN to another. And when it happens, traditional components have no idea how to react.

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!

Review: American Standard’s Champion 4 Toilet Flushes Almost Anything

July 31, 2012

Although most crappers are crap, plumbing companies like American Standard are hard at work innovating to eliminate the excrement. The current champion is fittingly called the Champion 4, and I have purchased, installed, and tested two examples of the type. The Champion is engineered to reduce the most common causes of clogs, and it has proved effective and “hands-off” in my real-world testing.
