vSphere 6: NFS 4.1 Finally Has a Use?

February 3, 2015 By Stephen 2 Comments

Way back in the 1990’s, UNIX admins delighted in upgrading from NFSv2 to NFSv3. Then NFSv4 came around and … crickets. Now VMware has become the first major/useful/mainstream application for NFSv4.1, so the floodgates are open! But are they?

Storage Changes in VMware vSphere 5.1

September 4, 2012 By Stephen 6 Comments

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.

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.

10 Mysteries The Lost Finale Definitively Settled

May 25, 2010

The series finale of Lost didn’t settle every question, but it did settle many of the long-running questions raised by fans. Although my live viewing was frustratingly complicated by failed transmission equipment at ABC affiliate, WEWS, I was able to watch the entire episode thanks to iTunes. So let’s settle the things that can be settled regarding Lost.

Frequent Flier Kung Fu for Novices

March 12, 2012

If you’re careful, even an infrequent flyer can rack up valuable points and maybe even elite status. But don’t do anything foolish, and don’t be fooled by the promises of first-class treatment. Even top-tier frequent flyers sit in coach most of the time!

Follow the Yellow Brick Road to the Software-Defined Future

November 29, 2012

The Software-Defined Datacenter is a great concept, but it just won’t work. The big enterprise companies will never allow VMware (and daddy EMC) to commoditize them out of existence, so useful implementations will be rarer than ruby slippers. The best we can hope for is point enhancements to enable greater virtual machine mobility through SDN and improved storage integration.

From LAN Manager and SMB to CIFS: The Evolution of Prehistoric PC Network Protocols

March 22, 2012

Computers aren’t much good on their own. This simple fact was evident even at the dawn of the microcomputing age, and has never been more true today in the “post-PC” world. If the standard microcomputer is the “Wintel” box (Microsoft’s Windows, Intel’s CPUs, and all that implies) then the standard network services protocol is SMB. So let’s take a nice deep dive into SMB, past, present, and future!

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.

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.

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.

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!
