Apple Revs Xsan and Kills Xserve RAID?

February 19, 2008 by Stephen 3 Comments

Apple has an odd relationship with enterprise computing. Their Xserve server products are strong, as is Leopard Server, and they have an excellent SAN file system, Xsan, that they just updated. Yet, Mac OS X is the last major operating system with no volume manager (thanks to the antiquated HFS+), and it looks like the […]

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.

Storage Changes in VMware vSphere 5.1

September 4, 2012

As I have done since version 3.5, I’m charting the storage changes in VMware’s latest release of vSphere, 5.1. Unlike version 5, which included many new technical storage features, 5.1 mainly tweaks existing features and adds these new elements to the mix.

Scaling Storage In Conventional Arrays

November 19, 2013

It is amazing that something as simple-sounding as making an array get bigger can be so complex, yet scaling storage is notoriously difficult. Our storage protocols just werenâ€™t designed with scaling in mind, and they lack the flexibility needed to dynamically address multiple nodes. So my hat is off to these companies and others who have come up with clever ways to maintain compatibility while scaling out beyond the bounds of a single storage array.

Review: Blue Snowball USB Microphone

March 31, 2010

I’ve really jumped into recording podcasts, and am also an avid audio and video conference user. Wanting better sound, I upgraded my Logitech microphone to the highly-regarded Blue Microphones Snowball desktop USB microphone. Here are my initial thoughts.

Begun, the Patent Wars Have

July 9, 2012

Every day, it seems there is a new lawsuit in the mobile phone industry. HTC, Motorola, Google, Microsoft, and especially Apple and Samsung are actively litigating their way through a thicket of patents. The same is increasingly happening in the rest of the IT industry. But is all this bloodshed really about innovation? Or is it, as one federal judge noted, simply a new form of intense business competition?

Nimble Storage Rolls Out an All-Flash Array

February 24, 2016

It took longer than I expected for Nimble Storage to introduce an all-flash array, but their AF7000 looks to be a very credible offering. They’re targeting XtremIO and Pure with their marketing, but I expect HP, Dell, and especially NetApp to be cross-shopped more frequently. In that fight, I expect the Nimble AF7000 to be very attractive indeed!

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.

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.
