The Future of I.T. – There is an app for that

One thing I noticed while attending this year’s VMworld in San Francisco was how many people attending the event had iPads. Actually, it was the hottest item being given away by almost all the vendors in attendance at the show. I was lucky enough to get one of the iPads that EMC was giving away. I recently heard that the iPad is the hottest selling tech item in history so far. During VMworld I got a chance to see the VMware iPad application to control your virtual environment and was really impressed. I really think the iPad might have a chance to become the tool of choice for the IT admins to monitor and administrate their environment. I am hoping that by VMworld 2011 we will be seeing a lot more client applications written and ported to the iPad and/or other mobile devices.

How Many VM’s Can I Run?

I saw a question get posted on twitter that kind of intrigues me a little. The question was pretty straight forward. “How many virtual machines should I be able to run on a host?” That is really a fair question in itself but what I find intriguing is that this is the first question he asks. Is this really the first thing administrators think to ask when designing their environment? After all there is no set formula on how many virtual machines you can run on a host. You can be a little more exact when working with VDI because for the most part all the virtual machines would be set up pretty much the same way and the numbers can be a little more predictable. That would not be the case when working with server virtualization. You are going to have servers all with different configurations and amount of resources provisioned to the virtual machines. This variation is what will change your slot count and the amount of virtual machines you can run on the host.

VMworld from an Open Source Perspective

VMworld is clearly the largest dedicated virtualization conference, and yet from an Open Source perspective it is slightly disappointing because the VMware ecosystem naturally attracts proprietary software vendors, and also some of the more interesting activities in Open Source are through multi-vendor foundations which do not have the same marketing budgets as vendors themselves.

Nevertheless, there are a number of key Open Source players, and some interesting smaller players, represented at VMworld.

Quest + Vizioncore + Surgient = A Virtualization Management Gorilla?

The combination of Quest, Vizioncore and Surgient creates a company that for the first time has all of the management pieces required for an enterprise to be able to virtualize tier one applications and to automate the process of assuring service levels for these applications. This puts Quest in position to be a clear leader in the virtualization management market.

Working with VMware Update Manager Server

Have you ever considered the best way to plan, design and work with VMware Update Manager (VUM)? In the early days using VMware 3.x when VUM was first released, I would end up installing VUM on the vCenter server itself. After all, that was the recommendation from VMware at the time. I propose that this is no longer the case and I would like to present a list of best practices to follow when working with VMware Update Manager. This list came from VMware, but should only be considered as a guide. Each environment is different and your mileage may / will vary.

What Do You Think When You Hear The Word Host?

When you hear the term “host” when talking about virtual environment, what is the first thing you think of? For me, the answer is simple, a host is an appliance. For years now I have been standing on my soap box and preaching the power and fundamentals of automation in building and configuring your virtual environment. I came across a thread on the VMware VMTN Community Forum where a concerned individual was in a position that he was going to have to rebuild his host from scratch. What he did to get himself into this position was to run a hardening script on the host and then the host became broken and unusable. This person was concerned that he did not have a backup of the host and was looking for a way to rollback.
