VMworld 2011 Monday General Session

This is the session blog for the Monday general session. I’m fortunate enough to have arrived in time to get a seat at the blogger/press/analyst tables. While the network connectivity is good, the power is—unfortunately—not so good.

Technology Short Take #13

Welcome to Technology Short Take #13. It’s been a while since my last Technology Short Take, and much has happened (vSphere 5 was announced, HP discontinued the TouchPad and webOS, and I announced my move to Denver). Here are a few data center technology-related links that stood out to me over the last few weeks. I hope you find something useful!

Looking Again at VASA

In early August, I wrote a post titled A Deeper Look at VASA, in which I provided some additional details on how VASA (the vSphere Storage APIs for Storage Awareness) worked and some of the potential limitations of the initial VASA implementation in vSphere 5. My original post was not intended to slam VASA; rather, my goal was to provide some additional information about how VASA works so that users can appropriately understand how best to incorporate this functionality into their environments.

Thinking Out Loud: Logical Link Multiplexing (Sort Of)

Over the last few days I’ve been listening to some episodes of the excellent Packet Pushers Podcast, trying to learn about such things as Shortest Path Bridging (SPB) and 802.1Qbg. It’s this second item–802.1Qbg—that this blog post is about (indirectly).

A Deeper Look at VASA

Much has been said and written about VASA (the vSphere APIs for Storage Awareness), a key part of vSphere 5 and the “magic” behind the new profile-driven storage functionality. I recently had the opportunity to dive a bit deeper into VASA, and discovered some information that I felt was important to share with the virtualization community. This post probably won’t earn me any brownie points at VMware, but at least we’ll all have a better idea of what VASA can and cannot do.

Thinking Out Loud: What if vSphere Supported FabricPath?

Since attending Cisco Live 2011 in Las Vegas earlier this year (see my summary list of blog posts), my mind has been swirling with ideas about how various technologies might work (or not work) together. In the first of a series of “Thinking Out Loud” posts in which I’ll attempt to explore—and spur discussion regarding—how certain networking technologies might integrate with virtualization technologies, I’d like to explore this question: “What if vSphere had FabricPath support?”

Some Useful UNIX Commands on your Mac

Over the last day or so I’ve been messing around at the UNIX command line on my Mac, trying to find a workaround for a VPN policy that doesn’t allow split tunneling. (Just as a stupid side question, what is the security issue with split tunneling, anyway?) Along the way, I uncovered some handy commands for gathering information about the networking configuration of your Mac.
