Thank you Gabe and Brenda

September 14th, 2009

I’d like to take a moment to thank two people, Gabe and Brenda, for their new and continuous friendship. They hail from the Netherlands and the pair are two of the nicest, funniest, and fun loving people I’ve met. I was first introduced to them in person earlier this year in Cannes, France during the VMworld Europe 2009 virtualization conference. Gabe was attending as a VMware user and Brenda joined him to study conference attendees in their preferred habitat, as well as for some sight seeing. Being from the U.S., I was quite out of my environment while traveling for the first time in France but they made me feel welcomed, teaching me some of the local customs as well as bits and pieces of the French language: “Merci beaucoup” – “Thank you very much” – a valuable phrase for a clueless tourist to individually thank each person for their assistance.

I met up with them again at VMworld 2009 in San Francisco, CA. This time they treated myself, my wife, and my kids to a nice Italian dinner Thursday evening after the conclusion of the conference. In addition, they showered my children with authentic Dutch gifts. Gabe and Brenda, if you are reading this, we very much appreciated this – Thank You! I hope one day we will meet again so that I can reciprocate. Chances are good as I’ve mentally committed to attend at least one VMworld annually, expending whatever efforts it takes to get there.

Where can you find this dynamic duo?

Brenda maintains a very interesting blog called Virtual Gipsy which offers an Anthropologist’s perspective of a tight knit virtualization community. Follow her on Twitter: @b_renda

Gabe runs an excellent virtualization blog called Gabe’s Virtual World and is particularly good with video editing. Follow him on Twitter: @gabvirtualworld

Lab Manager Network Port Requirements

May 13th, 2009

I need to become a VMware Lab Manager expert and so it begins.  From what I’ve seen so far, Lab Manager 3.x has made great progress since I last kicked the tires 15 months ago on Lab Manager 2.x.  The biggest news by far is that ESX hosts can be managed both by Lab Manager Server and vCenter Server with all the fixins (DRS, HA, VMotion).  Although I’ve already found that VMs connected to an internal only vSwitch remain pinned to the host due to VMotion rules.

Nothing too Earth shattering here; this information comes straight from page 20 of the Lab Manager Installation and Upgrade Guide.

Systems TCP Port UDP Port
Client browser to access Lab Manager Server system 443
Client browser to access ESX hosts 902, 903
Lab Manager Server system and ESX hosts to access SMB share

(import and export operations only)

139, 445 137, 138
ESX hosts to access NFS media datastores or NFS virtual machine datastores 2049
Lab Manager Server system to access Lab Manager agent on ESX hosts 5212
Lab Manager Server system to access ESX host agent on ESX hosts 443
Lab Manager Server system to access the VirtualCenter Server system 443
Lab Manager Server system to communicate with virtual router on some ESX hosts

(for fenced configurations)

Lab Manager Server system to access LDAP Server 389 LDAP


Before the installation of Lab Manager, be sure that ports above won’t conflict with an existing configuration by running the netstat -b command from the Windows command line.

Cloud Camp Minneapolis

April 18th, 2009

IMG00028-20090418-1006Today I attended Cloud Camp Minneapolis from 9:00am to 3:30pm on the University of Minnesota East Bank campus. I think the event was large success. Registration was SOLD OUT and it looked like there was somewhere between 100 and 150 attendees. I think it speaks well for the technology and the event organization when that many people will give up the majority of an absolutely gorgeous Saturday.

The event started with a continental like breakfast where people mingled and socialized for an hour before the speaking agenda began. I ran into a few familiar faces and also met with new people I hadn’t met before. The coffee was strong and the bagels looked good.

After breakfast, we were ushered into the main auditorium. George Reese (pictured top left), cloud book author and event organizer from enStratus Networks, kicked things off by briefly introducing himself as well as the premier sponsors: VISI, enStratus, Microsoft, Hosso The Rackspace Cloud, Aserver, and Right Scale.

Shortly after, the Lightning Talks began. This is where the premier event sponsors were allowed just a few minutes to deliver their cloud speech along with a little product marketing while literally whipping through their slide deck. When I say just a few minutes, I literally mean it. I think five vendors all got up and delivered their presentations in a total of 15 minutes. If you’ve ever watched the television program “Mad Money”, it was like cloud talk and offerings during the lightning round. It was both an interesting and refreshing approach.

Next we had a lengthy group discussion on hot cloud topics which were in turn used to dynamically develop the afternoon breakout session topics. We touched on things such as security, mobility, legal and liability implications, small business, etc.

We broke for lunch where I had discussions with a few locals on phone, cable, and internet service providers (ISPs) in the state of Minnesota.

After lunch the large group broke up into the smaller breakout sessions mentioned previously. I attended two sessions: Mobility and SMB.

The mobility session had a good crowd mixture comprised of service providers, application developers, and CEOs. The discussions jumped from topic to topic as people offered up their problems, questions, and philosophies orbiting cloud mobility and isolation. Not to my surprise, there was very little along the lines of answers or solutions. That’s ok. I wasn’t expecting any. Frankly, I found comfort among large numbers of industry experts who, like I, didn’t have the answers and were just as perplexed about figuring out how this is all going to work out. Developers seemed to be the most concerned about the application layer (Applications as a Service) as discussions touched on APIs and applications in the cloud and their impact on development techniques as it applies to mobility. I got a sense of less concern over platform in the cloud, also known as Platform as a Service. One developer talked about his current experience of using Amazon’s Elastic Compute Cloud (EC2). His direct benefits: he owns and supports nothing, and he pays only for what he uses. When he’s not using it, there’s essentially little or no cost. When he’s done, I imagine he saves what he needs, and the rest is destroyed. There is no traditional decommissioning and writing off of assets. There is no hardware that needs to be disposed of properly.

The SMB session was another good mixture of attendees nearly the same as above but with more of a concentration on small business, as well as micro and nano business (phrases coined during the session representing entities smaller than small business). The general idea of this session was if and how small businesses can benefit from cloud offerings. Talks began with the various ways to define a small business: by revenue? by headcount? by technology? There are examples of large manufacturing plants that have small technology footprints. Likewise, small operations can generate large amounts of revenue with the assistance of technology. Group members proposed that there exists many inefficiencies in small business, particularly in the technology and infrastructure. This is where renting platforms, applications, services, and infrastructure from cloud providers could make sense for SMBs. Wouldn’t small businesses rather focus their time and energy on developing their products and services instead of being tied down by the technology they need to run their business on? From a customer or partner credibility standpoint, does a business look more professional and equipped running their business in a certified cloud datacenter, or a broom closet? What impacts will regulation and legislation have? Decisions of how to securely store and deliver customer information in a small business shouldn’t be taken lightly. There are consequences that could easily break the trust and financial backing that a small business or startup’s survivability relies on.

In all, I had a great time at Cloud Camp Minneapolis. If you asked me six months ago what I know about the cloud, I would have had nothing to say other than “I don’t get it”. I’ve gradually been warming up to the concept and today Cloud Camp Minneapolis went a long way in delivering my first feeling of personal and professional accomplishment in that I think I’m actually caught up and on the same page as many of my peers and higher experts in the cloud community. However, I have to be honest in saying that I walked away somewhat disappointed and in disbelief that virtualization discussion was nearly non-existent. The last two VMworld virtualization conferences I attended in Las Vegas and Cannes were strongly focused on cloud computing and VMware’s Virtual Datacenter OS (VDC-OS). There was maybe one mention of VMware in one sentence and a brief reference to VDI. Microsoft was on site talking about Azure and there was no mention of Hyper-V. No mention of XenServer, Virtual Iron, etc. I’ve been led to understand that virtualization is key component to cloud infrastructure, applications, and mobility. I anticipated much of today’s discussions would revolve around virtuailzation. I couldn’t have been more wrong. After the event finished, I sent out a tweet re: no virtualization talk today. I received a response stating virtualization is merely a widget or one small component among many in the cloud. Virtualization is not really as integral as I’m being told by Paul Maritz of VMware. Maybe this is a case of Jason has been drinking too much VMware Kool-Aid for too long. The answers about the cloud are coming. Slowly but surely. Hopefully Paul is right and VMware does have a significant role to play in their version of global cloud computing. I’d like to see it, realize it, and experience it.

Twitter outage

February 19th, 2009

I don’t see this often (in fact I’ve never seen this) so I thought it was blog worthy given the increased use of social media as a professional’s tool.

Where to get timely VMware virtualization information

December 25th, 2008

Happy Holidays!  I thought tonight was the night I was going to post some “Citrix XenApp virtualized on VMware ESX” that many have been asking me for behind the scenes, but alas it’s 10:30pm and I just don’t have the energy for such a post that will require considerable effort to put together.  I’ve accumulated some information here and there for various people, but it’s time to formally consolidate the scattered pieces of information into one decent post that I can fine tune as needed going forward.  Before you start licking your chops in anticipation of a rocket science blog post on virtualizing Citrix, please don’t.  What I promise is the details and discoveries behind one person’s virtualized Citrix environment.  With VI3, virtualizing Citrix is fairly straightforward but extra special attention must be paid in determining virtualization candidacy.

Now I wouldn’t want anyone to walk away empty handed from my blog on Christmas so I leave you with this:  A no-frills post revealing the source of where I get 90-95% of my daily virtualization information – RSS feeds of various blogs and websites.  This file (right click, save as – it’s XML) contains an export of all of my RSS subscriptions.  Import it into your favorite RSS reader.  Set your RSS subscription refresh interval to 15 minutes.  Stay informed with nearly up to the minute and late breaking VMware virtualization news.  With new blogs and sites popping up weekly, for sure this list is nowhere near what I would call complete.  If you have any suggestions or if you see a great blog or site that I am missing, by all means, let me know in the comment section below.  I’m the type of guy that can never get enough VMware virtualization information.

Disclaimer:  My RSS subscription list contains a few subscriptions to non-virtualization related feeds which you may want to remove.

Update:  I’ve added two more great blogs to the RSS feeds:  Gabe’s Virtual World (Gabrie van Zanten) and Jase’s Place (Jason McCarty).

Further unwrapping of the free tool from Veeam

December 18th, 2008

Rich Brambley of VM /ETC allowed me to take a look at the Veeam present located under his tree.  Due to our carelessness, more wrapping paper seems to have been worn away!

Can anyone guess what this tool might be?  I’ve got a hunch and my guess can be found in the form of a tag below this blog entry.

Be sure to register for free copy of this tool being made available by Veeam on December 22nd!

Happy Holidays!
