There was a big buzz going around on Twitter this morning about memory management mechanisms implemented by the VMkernel in the event that a Guest OS has a limit set that is under its total assigned value. The conversation was kicked off from Arnim Van Lieshout's blog post on memory management. This is NOT a good scenario to have in your ESX environment, and I have seen it many times due to lack of education on what setting a limit means, or simply having a bad template deployed throughout the environment. I want to start by saying that I am not 100% sure this is exactly what the VMkernel does, but having seen it, troubleshot it, and written rules in enterprise virtualization monitoring products around the behavior, I have a pretty solid base of understanding.  |

For the first time since I started working for an ISV around virtualization, one of my independent submissions has been approved for a VMworld event. I do not know the exact time and date of my session just yet, but as the schedule is finalized, be sure to look for my session titled: Avoiding Pitfalls: The Hidden Costs of Managing your VMware Infrastructure. A summary of the presentation is below. As with all presentations I give, I add quite a bit of real-life experience and detail into helping others avoid the mistakes I had to uncover the hard way! Avoiding Pitfalls: The Hidden Costs of Managing your VMware Infrastructure Server virtualization has brought significant efficiencies to IT operations, but at the cost of new challenges in monitoring the health of running virtual machines, analyzing data, alerting staff in case of a problem, and performing administrative tasks. These challenges are growing as virtualization takes an increasingly central role in IT. System administrators are investing more time and effort into ensuring the proper operation and health of VMs, yet lack tools comparable to those available for physical servers. Join Scott Herold, Lead Architect for Virtualization Solutions, at Quest Software who reveals how the growing complexity and lack of resources necessitate changing the way IT operations are commonly performed. Key takeaways include: - Understanding server workloads and better identifying virtualization candidates
- Addressing the challenges of monitoring the virtual infrastructure
- Reduce internal fire-fighting by adopting more mature operational processes
- Prioritizing issues based on the impact to the business and on end users
- Reducing administration costs through proactive management and automation

On occasion I'm contacted by someone in Quest's PR Department to provide a paragraph or two, or some tips and tricks to virtualization for "Something they are working on" without any real knowledge (or care for that matter) as to what its for. I figure the sooner I complete it, the sooner I can get back to the task at hand for the day. Well this time I actually have a chance to see the results of my efforts on an eWeek.com article entitled How to Ensure Your Virtualization Initiatives Effectively Support Applications and Users. You'd almost think the people naming these articles should be the people thinking up the next name of our books... Anyways, if you have 5 minutes available, go ahead and give it a read, it actually has some useful information in it and doesn't shove marketing down your throat (One of my standard stipulations that I like to try and adhere to). |

As we kindly pointed out on page 272 of the new VI3 Book, we have a very thorough document written by Rob Zylowski, who is an awesome consultant not just for virtualization, but one of the best in the Windows and networking space that I have ever had the pleasure to work with. Ron, Mike, and I put aboslutely NO effort into this document. It is 100% Rob Zylowski. Unfortunately, it was cut from the book due to its mammoth size. It weighs in at 75 pages. This is the most thorough document of understanding the back-end database structure of VirtualCenter I have ever seen. |

As I mentioned in an article a few days ago, I will be representing Vizioncore at the Virtualization Congress show taking place in London from the 14th - 16th of October. I actually had every intention of releaseing my primary presentation that was rejected by VMware for the VMworld 2008 show to the public, but was stopped by my marketing team when this opportunity presented itself. With a slightly extended preparation time, and a much more interesting presentation format, I'm quite excited that I'll be able to provide some valuable information to the community about the future challenges surrounding virtualization, and how to meet them head on.
Yes, I realize the abstract describes me as a Vizioncore employee. I find that I often need to bring shirts for 3-4 different companies to various shows depending on exactly what I'm talking about on that particular day. |
