Who to vote for?

This week Eric Siebert opened up the 2014 edition of top virtualization blog contest. For the industry this is one of the highlights and applaud the effort Eric and his team of volunteers put in to make this work. I cannot wait to the watch the show in which they unveil this years top 25 winners. A big thank you to Eric and the team!

Most of the time you will see blog articles that highlight this years effort and I think they are great. As there are so many great bloggers writing and sharing their thoughts and ideas, it’s very easy to miss out on some brilliant post. A quick scan of these posts helps to (re)discover the wealth of information that is out there.

Last year I was voted number 2, however this year the frequency (hopefully not the quality) of my blog articles went down. This was due to my career change and the new responsibilities my job role encompasses. Plus creating the vSphere design book took a lot of time and effort. For this years VMworld we have planned something even better, so please stay tuned for this years VMworld book!

But this post is not about me as a blogger and my material, but to highlight some of the bloggers that help the community understand the product better, comprehend the behavior of the complex systems we work with every day and the insights they provide by spending a lot of their (spare) time writing and creating these great articles. Voting for them you will help them understand that their time and effort is well spend!

First of all, guys like Duncan Epping, Cormac Hogan, William Lam and Eric Sloof relentlessly churn out great collateral, whether it is a written article, podcast or video. It keeps the community well fed when it comes to quality information. Writing a great article is a challenge, doing this on a continuous basis is even more impressive!

But I would like to highlight some of the guys that are considered “new” guys. They are all industry veterans, but they decided to pick up blogging recently. I would like to highlight these guys, but there are many more of course.

Pete Koehlervmpete.com
Pete writes a lot about PernixData, but that’s not the reason I want to highlight him. His articles are quite in-depth and I love reading those articles as I learn from them every time Pete decides to post his most recent insights. For example in the article “Observations of PernixData in a Production environment” he covers the IOPS, Throughput & Latency relationship in great detail. In this exercise he discovers that applications do not use a static block size, something you don’t read that often. He correlates specific output and explains how each metric interacts which each other, educating you along the way and helping you to do a better and more effective job in your own environment.

Josh Odgersjoshodgers.com
Josh is listed both on the general blogging list as well as a newcomer and I think he deserves to be “rookie of the year” Josh’s insight are very valuable and its always a joy to read his articles. His VCDX articles are top notch and are a must read for every aspiring VCDX candidate. Just too bad he decided to join Nutanix ;).

Luca Dell’Ocavirtualtothecore.com
Dropping knowledge both in English and Italian, Luca is covering new technologies as well as insight full tips and tricks on a frequent basis. Ranging from reclaiming space on a Windows 2012 installation to a complete write up on how to create a valuable I/O test virtual machine. A blog that should be visited regularly.

Willem ter Harmselwillemterharmsel.nl
Not your average virtualization blog, Willem covers the startup world by interviewing CEO’s and CTOs of the hottest and newest startups this world currently has to offer. Willem provides insights of upcoming technology and allows its readers to place and compare different technologies. A welcome change of pace after spending a day knee-deep into the bits and bytes

Consuming those stories and articles on a daily basis, are they helpful in your daily work? Please show your appreciation and vote today on your favorite blogs! Thanks!

The year 2013 in review

This weekend the mailman delivered my vExpert 2013 award and this made me think about all things that occurred in 2013. You can easily state that the move to PernixData dominated my whole year.

It was early February that I previewed FVP and from that moment on I was breaking my head on how to become a part of that story. On 29th of April I announced the news that I left VMware and to be honest I was amazed by the eruption that followed. My twitter timeline exploded and even sites like the register and ntpro.nl reported on my move the next day. It all felt unreal.

But leaving the mothership was not an easy decision, leaving so many great memories, colleagues and friends. VMworld was interesting as I was visiting VMworld FrankDenneman-VMware-MMs as a non-employee for the first time since 2010 and that meant, no Partner day, no Meet the Experts, no Group Discussions, stuff I really enjoyed doing. It would be great if VMware opens up Group Discussions or Meet the Expert sessions for non-VMware people.

Luckily I had the opportunity to join Michael Webster, Mostafa Khalil, Andrew Mitchell and Mark Achtemichuk to participate in the panel about High performance workloads in Monster VMs. The session was a great success and I enjoyed it very much, the audience enjoyed it as well as it was voted as one of the top 10 sessions of VMworld 2013.

A great project we released during VMworld was the vSphere design pocketbook. The Pocketbook functioned as a platform for community members to display and demonstrate their knowledge. Mimicking the ever so popular “Basic Design Principles” of the vSphere clustering deepdive books, vSphere Design Pocketbook. breakfast we ask community members to submit their design considerations in a compact message following the 140 character limit of a tweet message. The response was overwhelming, more than 400 people participated and we printed over 2500 copies. Having the ability to launch and work on such cool projects are one of the benefits of working at a startup.

Working for an early startup is a great experience, although you have a specific job title your responsibilities quickly expand beyond your core job duties. FrankDenneman-VMworld-PernixDataParty-University-Ave You get to learn a lot of new things fast. The last couple of months I took on the role as an System Engineer, helped to build channel, helped to setup partnerships, did some tech support, assisted marketing and assisted in the sales cycle. All while trying to evangelize the great technology of PernixData while providing engineers input and looking at future features. So far it has been an amazing ride!

So what’s next?
Well as the organization is growing I hope to focus more on spreading the word and educating the community. Hopefully blogging more and broaden my articles to the entire vSphere platform. Besides writing I’m planning to present more at VMUGs, I’m are working on nice schedule for next year. Providing a platform for the community was such a success that we already working on a couple of successors of the vSphere design pocketbook. Stay tuned!

A quick thank you!
I would like to thank all my readers and twitter followers in visiting the site, commenting on the articles and providing me valuable feedback. I would like to thank the sponsors, VEEAM, Unitrends, Zerto, CloudPhysics, Stratogen, VMTurbo and PHD virtual for their support allowing me to operate the site.

Awesome read: Storage Performance And Testing Best Practices

The last couple of days I’ve been reading up on EMC VPLEX technology as I’m testing VPLEX metro with SIOC and Storage DRS. Yesterday I discovered a technical paper called “EMC VPLEX: Elements Of Performance And Testing Best Practices Defined” and I think this paper should be read by anyone who is interested in testing storage or even wanting to understand the difference between workloads. Even if you do not plan to use EMC VPLEX the paper delivers some great insights about IOPS versus MB/s. What to expect when testing for transactional-based workloads and throughput-based workload? Here’s a little snippet:

“Let’s begin our discussion of VPLEX performance by considering performance in general terms. What is good performance anyway? Performance can be considered to be a measure of the amount of work that is being accomplished in a specific time period. Storage resource performance is frequently quoted in terms of IOPS (IO per second) and/or throughput (MB/s). While IOPS and throughput are both measures of performance, they are not synonymous and are actually inversely related – meaning if you want high IOPS, you typically get low MB/s. This is driven in large part by the size of the IO buffers used by each storage product and the time it takes to load and unload each of them. This produces a relationship between IOPS and throughput as shown in Figure 1 below.”

01-IOversusMB

Although it’s primarily focused on VPLEX, the paper helps you understand the different layers of a storage solution and how each layer affects performance. Another useful section is the overview of good benchmark software which describes the basic operation of each listed benchmark program. The paper is very well written and I bet even a joy to read for both the beginner as well as the the most hardened storage geek.
