What is VMware VDC-OS vStorage?

September 19, 2008 By Stephen 2 Comments

VMware packed a lot into their 2008 VMworld conference, including an outline of their “three pillars” strategy, focused on vClient, vCloud, and something they are calling the Virtual Datacenter Operating System. While it is debatable if this last item really is an operating system, it’s certainly a major strategic change in messaging. VDC-OS is divided […]

VMware Virtual Datacenter Operating System: Heavyweight or Hot Air?

September 16, 2008 By Stephen 6 Comments

Paul Maritz of VMware dropped a bomb on Las Vegas today, introducing their Virtual Datacenter Operating System concept. But is VDC-OS a nuclear strike at the heart of the data center, scattering everyone from Microsoft to Cisco to (big daddy) EMC? Or is it just more hot air, conflating the latest big thing into 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.

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.

Are You a Hypervisor Hugger or a Storage Stalwart?

November 14, 2011

The time has come to take sides on the core question of storage for virtual servers: Do you want storage intelligence to live in the hypervisor or the array? Most administrators are already lining up on one side or the other, unintentionally casting their vote while the rest flounder. But the storage industry must wake up and embrace the divide.

How To Sync Your iPad With Your Exchange Server

April 3, 2010

Did your new iPad arrive today? If you’re reading this, you’re probably wondering how to set it up with your corporate Exchange server. The good news is that Apple has been working on Microsoft Exchange integration for years, and the iPhone OS used in the iPad sports fairly complete Exchange ActiveSync support.

Mac OS X Lion Adds CoreStorage, a Volume Manager (Finally!)

August 4, 2011

Mac OS X was majorly deficient in that it lacked a volume manager. This wouldn’t seem like a big deal to the average user, but held back the operating system in so many ways. A volume manager brings storage virtualization to an operating system, allowing storage capacity efficiently to be managed and manipulated. But all this has changed in Mac OS X 10.7 â€œLionâ€ with CoreStorage.

Go Get a ProtonMail Account and Protect Your Online Life!

July 19, 2017

It’s an easy decision: Get a free ProtonMail account and use that as your verification address for important financial and social media accounts. Keep using whatever email account you like for regular communication, but don’t mix security and communication!

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.

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.

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.
