Top 25 bloggers 2013 results are out…

The top 25 bloggers 2013 voting results are out again. This year the competition was insane. With newcomers like Cormac Hogan and Chris Wahl, but also old-timers like Chad Sakac, Scott Lowe, Eric Sloof and of course Frank “resource management” Denneman.

First of all, a BIG THANK YOU to Eric Siebert who took the time and effort again to set this up. I know how much work these kind of things take, so once again thanks Eric for spending your evenings on this! There were over 80 new blogs this year and 4 new blogs made the top 25, and one new blog made the top 10. With a total of ~1300 votes this is probably one of biggest community awards I have seen. Yes being a vExpert is awesome, but getting votes from your readers feels 10 times better.

I am not going to list the full top 25 here, I feel everyone should hit Eric’s page for that. I do want to thank everyone for taking the time to vote for me. I am honored to have been voted number 1 blogger for virtualization again for the 6th consecutive time. This is crazy, who would have thought that when I started yellow-bricks.com years ago… I sure did not expect that, and it was also never my intention. Thanks everyone, and please keep coming back and leave comments – be interactive!

There are two bloggers I do want to call out, first of all someone who I managed to persuade to start his own blog and who entered the Top 10 as a newcomer… Cormac “the god of all things VMware storage related” Hogan. What a tremendous achievement this year by Cormac. So many great articles, not just deep technical but also his “storage vendor overviews” are awesome. Of course the resource management guru who jumped from spot 5 to spot 2, Frank Denneman. Awesome work, what can I say more?! Keep it up,

Once again, make sure to watch the vChat below and hit Eric’s page for the full list. Thanks everyone, and see you next year :)

Vote for the top virtualization Blogs / 2012 looking back!

Yes, it is that time of the year again… vSphere-land.com’s voting for the top virtualization blogs has started again. Of course I am hoping to end up somewhere at the top of the list again, but I realize like no one else that this is not a given. The competition once again is huge, there are a couple of new-comers which has published some outstanding work. Personally I am a huge fan of Cormac Hogan’s work and I hope he will make it in to the top 10 this year, I sure as hell voted for him! Of course I expect my friends like Frank Denneman, Alan Renouf, Massimo Referre and William Lam to also hit the top 10.

I am hoping each of you will select the top-10 blogs again based on quality, relevancy, longevity and frequency. (I personally find length of the article irrelevant, content is King!) I always use the yearly voting to look back at what happened the last 12 months. What happened in 2012, what has kept me busy?

For me 2012 started with Partner Exchange. Presented a 2-hr workshop on how to design a Cloud Infrastructure, together with Dave Hill (he is on the list as well, so vote for him :-) ) and guests Frank Denneman and Chris Colotti. On top of that Chris Colotti and I presented a DR solution for vCloud Director based environments. This is something that people had been waiting on for a long time. I came up with the process/concept for this and also published a whitepaper on this topic. The same concept can be used for VMware View environments by the way, white paper out soon! I published a whole bunch of other white papers (1, 2) this year as part of my Tech Marketing responsibilities, of which the vMSC Best Practices paper is probably the most read and best received. I managed to get a couple of sessions approved at VMworld and had a blast presenting with my buddy Lee Dilworth. Also being a VMworld “Expert” was once again an awesome experience, I especially enjoyed the group discussions. I also presented as a couple of VMUGs (belgium, ireland, uk) and last but not least, published the vSphere 5.1 Clustering Deepdive… which happened to be the most sold book at VMworld San Francisco.

Along the way I managed to crank out an article or two hundred, and my blog went down during the vSphere 5.1 launch due to the massive amount of traffic. I can tell you that my hosting company was surprised as they thought it was a DDOS attack, but then they figured out it was just a massive amount of people hitting my site on the same day. I guess thanks for that :-)

I did want to list my 10 top articles over the last 12 months in no particular order:

Thanks again to Eric Siebert who spends a MASSIVE amount of time going through the voting, filtering out discrepancies and making sure it all is done in a fair manner! Make sure to bookmark his website, add it to your RSS reader and follow him on twitter. So what are you waiting for, head on over and take the survey!

vMotion over VXLAN is it supported?

I have seen this question popping up in multiple places now, vMotion over VXLAN is it supported? I googled it and nothing turned up, so I figured I would write a short statement:

In vSphere 5.1 (and earlier) vMotion over VXLAN is not supported.

This statement might change in the future, it could be that in the next version vMotion traffic over a VXLAN wire will be supported, but with the current release it is not. Do note that vMotioning virtual machines which are attached to a VXLAN network is supported.

The next question people ask typically is, will it work? Yes it probably will, but again… it is not supported. Keep that in mind when you are designing a multi-site environment and want to use VXLAN.

Storage vMotion does not rename files?

A while back I posted that 5.0 U2 re-introduced the renaming behavior for VM file names. I was just informed by our excellent Support Team that unfortunately the release notes missed something crucial and Storage vMotion does not rename files by default. In order to get the renaming behavior you will have to set an advanced setting within vCenter.. This is how you do it:

  • Go to “Administration”
  • Click on “vCenter Server Settings”
  • Click “Advanced Settings”
  • Add the key “provisioning.relocate.enableRename” with value “true” and click “add”
  • Restart vCenter service or vCenter Server

Now the renaming of the files during the SvMotion process should work again!
All of you who need this functionality, please make sure to add this advanced setting.

Awesome appliance, vCenter Support Assistant

Today an awesome appliance called the vCenter Support Assistant was made available to the world. I have seen some screenshots and a demo and feel that this appliance is a MUST HAVE for anyone who files Support Requests. Just the fact that you can do that from a single interface, which also allows you to upload the support bundle just makes life a whole lot easier.

Ryan Johnson wrote an excellent article on this topic… and I am going to steal his thunder so I suggest you head over to the VMware TAM Program blog (open to everyone) and read up on this excellent Appliance.

Fixed: Macbook waking up every hour or so

For the last months I have people asking me why on earth I was on google talk / messenger in the middle of the night, but then did not respond when they said hi. It appears that my Macbook had been waking up roughly every hour while I had put it to sleep.

At first I thought it was the messenger software I was running called Adium. But after closely checking this didn’t seem to be the problem. Then I started digging and checked my log files. My log files did reveal something:

syslog |grep -i "Wake reason"
Jan 12 00:37:59 Depping-MBA kernel[0] <Debug>: Wake reason: RTC (Alarm)

So I did a quick search on “RTC” and stumbled on this article which explained why this was happening. The article refers to an Apple KB, which hints at what to disable. When disabling “Wake for network access” as suggested by the KB I noticed another feature called “Power Nap”. It appears that Power Nap also enables your Mac to do certain things on a regular interval. For instance it can allow for a backup to occur or it will check email every hour.

Prevent Macbook waking up

In my case there is no need to power-on in the middle of the night to do these things, so I disabled both “Wake for network access” and “Power Nap”. There is some more info about “Power Nap” to be found in this KB article.

My Bookstore

I had various people asking why I didn’t make it easier to buy my books via my website. Greg Schulz from StorageIOblog.com mentioned that he created an amazon store. So I took a peek at how he set it up and kinda did something similar. If you click “My Bookstore” at the top you will be automatically brought to a custom Amazon store. It will list all my books on the first page, paper copies that is. On the right side you have two more options:

  • Kindle Items – ebook versions of what I have published so far
  • Books by Friends – exactly what it says… books that my friends have written

Over time of course new books will be added to the appropriate sections. Thanks and I hope it makes things easier.
