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 […]

Xen 3.3 Update Brings Paravirtualized SCSI

August 28, 2008 by Stephen Leave a Comment

One of the new features in Xen 3.3, released this week, caught my eye: Paravirtualized SCSI (PVSCSI), which allows a guest OS to directly interact with a SCSI (or Fibre Channel) HBA. This should allow more specialized applications to be virtualized in Xen environments that use SCSI or FC storage without requiring the addition of […]

VMware Acquires Virtualization Management Firm, Dunes

September 11, 2007 by Stephen Leave a Comment

There was lots of speculation last month about what VMware would do with all that post-IPO cash. Well, today at VMworld, the company announced it had acquired Swiss virtualization management company, Dunes. This just hit the wires, and there’s no information as of now on either company’s web site. It looks like this will add […]

SRM For VMware (Thank God!)

August 1, 2007 by Stephen 2 Comments

So Symantec’s CommandCentral version 5.0 includes VMware-integrated SRM. Thank god! Has anyone out there been banging their head against the wall trying to figure out what’s taking up all their unstructured filesystem space? Well trying to get that information in a world of VMware virtual servers is like drilling through your forehead with an auger. […]

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.

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

What’s the Difference Between a Jailbroken and an Unlocked Phone?

May 5, 2012

If you’ve traveled much, you’ve probably run across â€œunlockedâ€ mobile phones and devices. If you own an Android or iPhone smart phone, you probably also heard about â€œjailbreakingâ€. It seems like lots of people are confused about these two things, so I decided to write down a quick post explaining them.

Ten Terrible Apple Products

June 14, 2012

I’m often accused of being an Apple fanboy. While it’s true that I love my vast selection of fruity products from Cupertino, I’m not blind when the company makes mistakes. In fact, I think Apple’s mistakes are as enlightening as their successes: They reveal a company that is fallible, sometimes learning but often allowing the junk to rot far longer than other companies would.

VMware’s Hardware Partner Strategy: Heads I Win, Tales You Lose

February 11, 2013

VMware is in an enviable but tricky situation: The company must work closely with hardware partners, keeping these prime sales and promotional channels happy and supportive. But VMware must also innovate around proprietary OEMs, subverting their products with integrated software before a rival steps up with an integrated alternative.

Smartphones, computers, and iPads are proliferating in families today. Although my three kids do not (yet) have their own mobile phones, we still have quite a few devices with calendar functions: An iPhone each for me, my wife, and our au pair along with an iPad and a few computers. Using Google Calendar, we have set up an awesome shared calendar to keep all of our activities in sync. Read on for instructions!

A Complete List of VMware VAAI Primitives

November 10, 2011

VMwareâ€™s introduced the â€œvStorage APIs for Array Integrationâ€ (VAAI) in vSphere 4.1, and block-heads like me went nuts. Weâ€™ve been trying to integrate storage and servers for decades, and VMwareâ€™s APIs finally allowed this to work in truly seamless fashion. But the world of VAAI is a thicket of bizarre naming and puzzling functionality. Some VAAI primitives are ignored or even hidden! Letâ€™s take a look at the complete list.

The Best Mac OS X Terminal Font: Glass TTY VT220

October 6, 2015

More than five years ago, I blogged about a “stupidly cool” terminal font. Now that Mac OS X isn’t a big cat anymore, I figured it was time to repeat that: If you’re an old-school computer nerd like me, Glass TTY VT220 is the coolest terminal font for Mac OS X!

The Prime Directive of Storage: Do Not Lose Data

December 12, 2014

People call on storage devices and systems to do lots of things, from accelerating I/O to copying and sharing data. But at the heart of it all, storage arrays really have just one job: Do not lose data!
