EMC Elect 2016 – Thank you!

Today I was officially named as an EMC Elect 2016, my 2nd year in a row and 3rd overall year in the program.  To say I’m honored and thrilled is an understatement! A while back I remember Duncan Epping saying something on Twitter similar to, “Everyone at VMware should be a vExpert.”  I’m paraphrasing but his sentiment is clear – if you work for a company, you shouldn’t need an award to incentivize you to evangelize that company’s products.  He’s absolutely

Resolving .NET path issues when installing vRA App Services bootstrap

UPDATE: Much as I tried to get this to work with Windows Server 2012 R2, it won’t.  You need to install .NET 2.0/3.0 on Windows Server 2012 R2 in order to get the bootstrap service to work.  It will install everything properly but I was unable to get the Windows service to actually start without .NET 2.0/3.0. See screenshot to show the .NET version that is required. As I continue on my vRealize Automation Application Services journey, I thought I’d

Find the right JRE filename when installing vRA Application Services Agent

As I said in a previous post, these days I’m more focused on cloud automation and orchestration than virtualizing business critical apps like I have been in the past.  However, combining those two worlds is of interest to me so I’ve been playing with vRealize Automation Application Services. I was recently preparing a Windows Server 2012 R2 template to be used as a template for vRA/Application Services and so I was following VMware’s documentation on how to install the required

The one where TiVo taught my wife about hybrid cloud

There’s a famous quote that says, “If you can’t explain it simply, you don’t understand it well enough.” That statement is true. But I’m sure many of us have examples of where we’re challenged to explain something we know very well in a simple manner. Take the example of working in technology and explaining what you do to family or friends who are in completely different fields. Can you easily explain virtualization, for example, to your car mechanic? What about

VMware Certified Professional Delta Exam

This weekend I had the opportunity to take the VMware Certified Professional Delta exam (VCP550D) to renew my VCP5-DCV certification for another two years.  I wanted to share my thoughts on this exam specifically as well as the future of online exams. I’ll echo what I’ve read from other folks regarding this exam in that you need to know more than just what has changed between vSphere 5.x and 5.5.  Be prepared to answer questions about vCOPs and VSAN and

Virtualizing Microsoft Lync 2013

It seems there is a bit of an uproar about a document Microsoft recently released called Planning a Lync Server 2013 Deployment on Virtual Servers. In that document, Microsoft makes some odd recommendations when virtualizing Lync, sync has disabling NUMA on physical servers and not using hyperthreading. To address these concerns, VMware has published a really nice blog post that addresses the unusual guidance in the document.  You can read the blog post by clicking here. The author of the

Thoughts on EMC Enterprise Hybrid Cloud

I’ve never been a prolific blogger like others in the virtualization community, but this year was especially bad.  One of the reasons is that I’m in a new role with EMC which has changed my focus a bit.  Still focused on virtualization, but less so on the business critical apps that I used to write more frequently about and more on hybrid cloud.  The other major change is my involvement with something called EMC Enterprise Hybrid Cloud, or what we

Thoughts on changes to TPS behavior in vSphere

This week VMware released a blog post and several knowledgebase articles about Transparent Page Sharing (TPS).  In the next patch for ESXi, TPS will be disabled by default between virtual machines.  TPS is the technology that allows virtual machines running on the same ESXi host to share identical memory pages, allowing ESXi to overcommit memory.  This technology has been part of ESX/ESXi for years and is one of the (many) differentiating factors between it and other hypervisors. VMware made this

Blogging is hard

As I type this, I see I haven’t written a blog post in over 5 months.  I wish I had a good excuse for that but I don’t.  The truth is it was really a number of different things: 1) Writing 3 books in one and a half years (from Nov. 2012 to April 2014) consumed a huge amount of time and made it hard to find time to blog.  Once the books were done I was a bit burned

vSphere Performance: The story behind my new book

I’m very happy to announce that my new book called VMware vSphere Performance, along with co-authors Rynardt Spies and Christopher Kusek, has been released! It’s available right now on Kindle format and the hard copy will be available on May 12th! The book is focused on providing guidance for how to design vSphere to get the best performance out of your virtual machines.  I wanted the book to be more than a paperback version of vSphere’s own performance best practices
