2 TB Enterprise Drives Are Here?

August 14, 2009 by Stephen Leave a Comment

That didn’t take long! Less than a month after Hitachi introduced their 2 TB enterprise disk drive, Xyratex has announced that they will offer the drive in their OEM storage systems. The A7K2000 is 7200 rpm 5-platter design with a 3 Mb/s SATA interface: Not exactly high-end, but backed by the reputable folks at Hitachi […]

Turning the Page on RAID

September 14, 2008 by Stephen 4 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. It has been the core technology behind the storage industry since day one, but the sun is setting on traditional RAID technology. After two decades of refinement and fragmentation, we are […]

Garth Gibson: Still Relevant After All These Years

August 13, 2007 by Stephen Leave a Comment

Garth Gibson, author of the seminal paper which presented the redundant array of inexpensive independent disks (RAID) to the world, has a nice quick interview over at eWeek. It’s worth a read, since Gibson’s long been on the forefront of storage tech. He talks about how parallel NFS (pNFS) is set to trickle down to […]

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.

Why You Should Never Again Utter The Word, “CIFS”

February 16, 2012

CIFS is not the network storage protocol used by Microsoft Windows, and many other clients. The protocol used to share files over a LAN by the majority of personal computers is called SMB. I wish everyone in the industry would get that through their heads.

Marketers: Fudging the Meaning of Buzzwords Matters (To You!)

December 2, 2015

Too many marketers and salespeople play fast and loose with words, but they’re only hurting themselves. Improper usage is embarrassing and causes a loss of credibility with the people they most want to reach. It would be wise to spend a lot more time being correct and a little less time jumping on bandwagons and buzzwords!

The Four Horsemen of Storage System Performance: The Rule of Spindles

August 25, 2010

Why do some data storage solutions perform better than others? Mechanical performance, RAM caching, I/O capacity, and the intelligence of the system all have a part to play. Today we examine the rule of spindles: Adding more disk spindles is generally more effective than using faster spindles.

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!

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.

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 […]

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!

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.
