What Is A UASP Storage Enclosure?

December 7, 2015 By Stephen 3 Comments

UASP has a lot of promise, bringing SCSI performance and features to the ever-expanding world of USB storage devices. But support has been haphazard, especially for Mac OS X and Linux, and this limits its impact. It would be nice if storage vendors could work with operating system developers to better support this storage protocol.

Yes, FireWire is Faster Than USB

July 30, 2008 By Stephen 1 Comment

This should not come as a shock to anyone, as it has been proven before, but let me take this moment to say that, yes, despite their rated speeds, 400-megabit FireWire S400 (aka IEEE 1394) is faster than 480-megabit USB 2.0. While swapping out disk drives (first to upgrade the internal drive in my MacBook […]

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.

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!

The I/O Blender Part 1: Ye Olde Storage I/O Path

May 23, 2012

This old-fashioned, predictable storage I/O path was deterministic and decipherable: The server, the switch, and the array all had enough information to do their jobs effectively and efficiently.

The End of Unlimited Data – Part 1: The Buffet

June 2, 2010

The headlines are all over the blogs: AT&T announced today that they are doing away with “unlimited” data plans and replacing them with limited packages at lower prices. I’m not going to repeat the news – Boy Genius Report has the best overview I’ve seen. Instead, I’m going to explain why I think this is a positive move for everyone involved, including AT&T, the customer, and the US wireless phone industry as a whole. This first post talks about the buffet mentality that got us here.

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 At The Client

November 25, 2013

Scaling storage is a serious challenge for the industry, but there is a great deal of thought, effort, and creativity going into it right now. Companies like Gridstore, Oxygen Cloud, and Cleversafe have come up with effective client-side solutions to enable scale-out storage to sing. If you’ve got an appropriate application, client, or gateway, scale-out is a real possibility!

What’s the Deal with Containers?

October 21, 2016

Lately, it seems like everyone just can’t stop talking about containers. But I’m sensing a distinct lack of real understanding of the technology from many people, not to mention lots of confusion about what containers really mean for today’s datacenter folks. So I set about learning more and figuring out for myself what the deal is with containers. Here’s where I’m at.

Deduplication Coming to Primary Storage

September 16, 2008

Although deduplication of storage is nothing new, with Data Domain and other making hay with the technique for years, it has never been ready for prime time – reduction of active primary storage applications like email and databases. Instead, deduplication has been relegated to second- or third-tier status, deduplicating archives and backup data. But change is in the air, and deduplication vendors are starting to bustle towards the bright lights of primary storage.

How to Get Me to Write about Your Company or Product

March 15, 2012

Blog posts are really, really important for PR and awareness these days. And posts on independent sites like this one are critical to get awareness and search engine ranking. I get dozens of requests every week from companies wanting me to write about them. So I thought it would be a good idea to lay out exactly what it takes!
