Kenneth is Speaking at BriForum Denver

I sat down with one of Lewan’s Solution Architects, Kenneth Fingerlos, to discuss his upcoming speaking engagement at the BriForum conference on July 20th.  Our brief conversation covered the details of his session, “vSGA, vDGA, vGPU, and Software – When and Why“, his background in the industry, and what gets him excited in the technology space right now.

Me: Kenneth, can you tell me a little bit about your industry experience?

Kenneth: So, after college I took a left turn in my career path and went into corporate IT for ten years.  Various positions: desktop management, server management, data center.  Various kinds of things.  After ten years of that I decided I didn’t care for IT management and tried to correct the course change and landed in consulting.  I’ve been doing IT consulting for about the last ten years around storage, data management, virtualization of various types, and building up my skill sets trying to help customers solve problems.

Me: Great, great.  So have you been to BriForum before?

Kenneth: I have not been to BriForum.  This will be my first year.

Me: What attracted you to BriForum?

Kenneth: I’m excited.  The whole idea of a conference that has some size to it and is established that is not tied to a specific vendor is just exciting, right?  You go to a Cisco conference and it is all about what is the latest widget from Cisco.  Cisco can do no wrong.  You find the same thing if you go to, you know, Dell World.  Dell is perfect.  Whatever Dell has got going is awesome and whatever everyone else has is garbage.  BriForum excites me because it is everybody. It is a marketing company–a media company that puts on the conference as opposed to a product manufacturer.

Me: So what will you be discussing at BriForum?

Kenneth: I’m discussing a topic that is near and dear to my heart which is the idea of virtualized graphics.  Taking things we do everyday in the physical world with physical PCs and trying to bring this into this virtualized environment.  Things like disaster recovery, security, flexibility.  You know, the physical world is pretty restricted.  Graphics have always been one of these things that is hard and is difficult.  Technology is evolving and has advanced dramatically over the last couple of years in terms of what we can do.  But there is also a lot of complexity and a lot of information and I find my customers have a lot of confusion about what they can and can’t do.  What works, what doesn’t work.  My session is all about trying to bring some clarity to that area.

Me: Ok, so I am going to open this up a little bit and say maybe don’t limit this to just the enterprise world but what is the technology you are most excited about right now?

Kenneth: The technology I am most excited about right now….I think the stuff that is most exciting is really this idea of graphics virtualization.  I mean, so many things go into a user experience, right?  And all of the traditional things that you think about: servers, storage, memory, CPUs–graphics is part of that.  Remoting protocols, right?  What’s going on with actually getting that content delivered to a user.  Networking, right? 3G, 4G networks and starting to think about what’s next, what’s beyond 4G.  These are huge enablers to let people consume and develop content in ways that have never been envisioned before.  Letting you take that stuff to the cloud, to the remote data center, and access it from anywhere.  I’ve been sitting on top of a mountain in my 4×4 holding a virtual desktop, just because I’m a geek and into this stuff, but yes–I can access that app, whatever it is, from a mountain top in the middle of nowhere.  That’s cool stuff. And it’s all about enabling people to work and function in ways they’ve never been able to before.  That excites me.

Me: Very cool.  Well, looking forward to seeing your session at BriForum!  Until next time.

As I wrote about earlier, BriForum Comes to Denver, and I am excited to have such a great event in my backyard.  If you are going to be at BriForum or just have general questions about Denver, reach out to either @kfingerlos or myself (@sagelikebrian) and let’s catch up.

VMTurbo, a unique way to better control your virtualized environments

Been trying out this VMTurbo stuff and it’s definitely a unique approach versus traditional systems management. It’s more actionable and automated versus telling me a bunch of information that I would have to decipher and deal with.  Both approaches have merit but it depends on how you’d like to control your virtualization environment that makes the difference.  Give it a try and let me know your thoughts.

Unable to get vCenter server certification chain error during vcOPs 5.8.1 install

During the deployment of the vcOPs vApp for a customer I ran into a new error – well, new for me. While the vApp (v5.8.1) deployed and booted fine, as I was registering it with the vCenter (v 5.1) as part of the initial configuration I got the following error: Unable to get vCenter server certification chain. Off we go to Google… Here’s a quick summary of things to check:

  • Confirm name resolution is working, username/passwords are right, etc.
    • Assuming Windows, RDP to vCenter with the user you’re attempting to use or try access via your favorite vSphere management tool
    • Hop on the console of the UI VM and ping the vCenter by IP and DNS name (username: root initial password: vmware)
  • Check that your vCenter certificate hasn’t expired. It’s the rui.crt file in c:\ProgramData\VMware\VMware VirtualCenter\SSL. This article has good info on locating and renewing your certificate, should that be your problem.
  • In the end, my fix came by importing the certificate file to the UI VM manually as outlined in this VMware KB article.
    • Full disclosure, the symptoms in the above article didn’t match my problem exactly and I don’t like just trying random fixes. However, when I found this Blog Post, in Spanish, with my exact error recommending a similar .cert import process I threw caution to the wind. The exact steps from the Spanish blog didn’t quite work, which could be a result of my inability to read Spanish and/or Google Translate not being perfect, but the VMware KB article was spot on.

After importing the certificate manually and restarting services, all was well and I was able to complete the configuration of vcOPs. By the way, did you know that since vSphere 5.1, all licensed versions of vSphere now include the Foundation edition of vcOPs? More than 5 hosts in your environment and you’ve got enough scale to warrant leveraging this tool. For a limited time, VMware is letting Lewan perform a free vSphere Optimization Check including a 60 day trial of the Standard Edition, complete with the capacity management features, dynamic thresholds, and root cause analysis. Give us a call today to test drive Operations Management!

Exchange Infostore will not start because of Vmhost time setting?

We recently had several clients whose exchange servers went offline for seemingly no apparent reason.  The servers were up and there were no connection or permissions issues, but we kept getting a strange error in the logs.

Error: Unable to initialize the Information Store service because  the clocks on the client and server are skewed.   This may be caused by a time change either in the client or the server,  and may require a reboot of that computer.   Verify that your domain is properly configured and  is currently online.

After investigation, we found that the Vmhost running the exchange server did not have the correct time set up.  We changed the time on the host (we actually enabled NTP to match the domain controller), and rebooted the exchange server.  The exchange server came up and the infostore started without error.  Everything was then fine in the world again.

How to Upgrade to VMware vCenter 4.1 from vCenter 4.0 32 bit Using the Data Migration Tool

Here is a very useful KB article on migrating an existing vCenter Server database to 4.1 using the Data Migration Tool:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1021635

Also, here’s a great blog post on VMware’s blog showing how to upgrade vCenter 4.0 32 bit to vCenter 4.1 64 bit by using the VMware Data Migration Tool.

http://blogs.vmware.com/kbtv/2010/07/how-to-upgrade-to-vmware-vcenter-server-41-using-the-data-migration-tool.html
Copied below for reference.

Our first video covering vSphere 4.1 is now live. The video compliments KB article 1022137 vSphere 4.1 upgrade pre-installation requirements and considerations. and describes the process for using our Data Migration tool to upgrade VMware vCenter Server 4.1

VMware vCenter 4.1 is part of the VMware vSphere 4.1 product suite and the Data Migration tool allows you to migrate your vCenter Server 4.0 configuration, since VMware has now entirely gone to a 64-bit platform. 64-bit brings significant performance benefits, but it also introduces some challenges that need to be considered before upgrading.

Sit back, grab that cup of java and take in a little KBTV.

VMware – Best Practice KB Articles for Installing vSphere 4.1 and vCenter 4.1

Here’s a great post over at www.vladan.fr (who’s a well known VMware blogger and vExpert) on some of the KB articles he’s found regarding best practices on installing vSphere 4.1 and vCenter 4.1.
http://www.vladan.fr/best-practices-kb-on-how-to-install-esx-4-1-and-vcenter/

Preparing the vCenter Server Installation Worksheet – Download and fill out the vCenter Server Installation Worksheet.
MicrosoftSQL Server 2005 Express is intended for use with small deployments of up to 5 hosts and/or 50 virtual machines.

    Memory – 3GB RAM. RAM requirements may be higher if your database runs on the same machine. VMware VirtualCenter Management WebServices requires 128Mb to 1.5GB of memory which is allocated at startup.Disk storage – 2GB. Disk requirements may be higher if your database runs on the same machine.

  • vCenter Server 4.1 requires a 64 bit DSN and MUST NOT be a Domain controller. vSphere Compatibility Matrix.
  • The computer name – no more than 15 characters.
  • have reliable DNS and Time services.

Recommended, but not mandatory:

  • separate database for vCenter Server and vCenter Update Manager

vCenter server needs all this (will be installed as part of vCenter Installation):

  • Apache Tomcat (64 bit)
  • Java Runtime Environment JRE (64 bit)
  • Active Directory Application Management (ADAM)
  • Visual C++ 2005 Runtime Redistributable
  • .NET 3.0 SP1 or above (optional based on DB selection)

If the machine on which you are installing vCenter Server has a previous version of vCenter installed (if it’s on 64 bit hardware), you might want to upgrade instead of performing a fresh installation of vCenter Server.

Best practices for the ESX installations:

Check on the HCL (hardware compatibility list) page…. – I blogged about that earlier too ….

  • System compatibility
  • I/O compatibility (Network and HBA cards)
  • Storage compatibility
  • Backup software compatibility

32bits installation are no longer supported. VMware ESX 4.1 only installs and runs on servers with 64 bit x86 CPUs.

  • Check the Enable Intel VT in the BIOS.
  • If you are installing to the local disks and you have a  SAN with Fiber Channel connected  to the ESX host, make sure and detach the fiber before continuing with the installation. (Do not disable HBA cards in the BIOS)
  • minimum size of the vmdk where the  /swap, and all the optional partitions are stored should be set for 8GB.
  • Make a separate partition for  /var/log.
