Content Creation and Mind Mapping

In conjunction with my shift to more “open” file formats such as Markdown (MultiMarkdown, to be specific), RTF, and OPML—a shift described a little bit here—I’ve also had two other shifts in my content creation process that I think are worth mentioning.

Updated Stretched Cluster Presentation

Last week I had the opportunity to speak to the Toronto VMUG and present an updated version of my talk on considerations for building stretched vSphere clusters. Stretched clusters are a topic I’ve touched on several times, first in Denver in June 2010, again this past May in Charlotte, and finally in Toronto last week. Last week’s presentation, found here, includes new and updated content for vSphere 5.

Technology Short Take #15

Welcome to Technology Short Take #15, the latest in my irregular series of posts on various articles and links on networking, servers, storage, and virtualization—everything a growing data center engineer needs!

Hidden VAAI Command

As some of you are probably already aware, one of the storage-related features added to vSphere 5 is support for the SCSI UNMAP command. While you would normally want this functionality enabled, there could be instances where you might want to disable this functionality. Unfortunately, there’s no option in the user interface to enable or disable SCSI UNMAP support.

Spousetivities at VMworld EMEA 2011

In case you haven’t heard already, the registration page for Spousetivities at VMworld EMEA 2011 is live and open for sign-ups! Crystal made the announcement about Spousetivities at VMworld EMEA on her site already, but I wanted to include it here as well so that everyone knew. Most of the activities sold out at VMworld US in Las Vegas, and Crystal’s hoping for similar success this year in Copenhagen. If you are going to be attending VMworld EMEA in Copenhagen and bringing your spouse/partner/significant other/family member, here are some of the things that are planned:

Exclusion or Not?

A couple days ago I read Stephen Foskett’s article “Alas, VMware, Whither HDS?”, and I felt like I really needed to respond to this growing belief—stated in Stephen’s article and in the sources to his article—that VMware is, for whatever reason, somehow excluding certain storage vendors from future virtualization-storage integration development. From my perspective, this is just bogus.

Determining an Optimal Design

I had an interesting e-mail conversation last week with fellow EMC vSpecialist Clint Kitson. Now, if you’ve never met Clint, he’s a super-sharp fellow, no questions about it. I love conversations with super-sharp folks as they invariably lead to new thoughts and new ideas, and this conversation was no different. The topic of the conversation, in generalized terms, was this: when crafting designs for customers, what defines an “optimal design”?

The Right vSphere Design Perspective

I was on a conference call the other day where the topic of the call was VMware View 5.0. If you attended VMworld—or even if you didn’t, it’s been kind of hard to miss—you know already that VMware made significant improvements to PCoIP in View 5. For one reason or another, the topic of the Teradici PCoIP offload card came up on the call, and other participants in the call were immediately asking about the availability of the card in mezzanine card format for blade server implementations. (Continue reading, and at the end I’ll tell you the answer I received to that question.)

The End of the Infrastructure Engineer?

Is the age of the infrastructure engineer over? While I was at VMworld 2011, I listened to a speaker talk about how people like me—people who are conversant in virtualization, networking, storage, servers, and data center hardware—are going to have to evolve/migrate into the application development space in order to survive in the “new cloud world” (my phrase, not the speaker’s). This speaker isn’t the only one, either. This started me thinking. Are infrastructure engineers really a relic of the past, like punch cards?
