As follow up to my previous post on VMworld 2012 Top 10 Most Popular Sessions, here is my second and the last nominated top 10 session for this year.
This session was called “VMware vSphere Cluster Resource Pools Best Practices”. In this session Frank Denneman and I discuss in detail what to consider and calculate when utilizing Resource Pools. This is a topic of extreme importance which has been covered and discussed many times by many of us in the community. This time around Frank put together a good amount of useful information and point out some of the major pitfalls of the use of resource pools. The dynamic resource management capabilities provided by the vSphere platform adds an immense value to any virtualized infrastructure and everyone should know and understand the details
Now, because of the importance and powerful role resource pools plays in the platform as it relates to performance, service level agreements, and integration with other products and solutions, it’s important to understand what they do, what they can be used for, when to use them, and when not to use them.
One of the biggest and most discussed gotchas related to the use of resources pools has been using them as folders. This type of use is loaded with risks and is the type of discussion Frank and I lead in this session amongst others.
Resource Pools are very useful for many reasons, but in order to use them correctly you have to know and understand the details. Our goal for this session was to deliver the deep technical information about resource pools in a very simplistic, and relatable format that everyone could understand. Basically, Frank talks about algorithms, logic, and numbers and make your brain hurt and then I made everyone hungry by relating the information in the form of pizza and pizza pie consumption.
The session was well accepted and people seemed to enjoy it at both VMworld events. For those of you that didn’t get an opportunity to attend VMworld this year here you go.
For those of you who didn’t get the opportunity to attend VMworld 2012 in San Francisco, and missed out on the sessions delivered by Frank Denneman, Chris Colotti, and myself on vCloud Director Allocation Models, and vSphere resource scheduling, don’t worry we got you covered. Frank Denneman (@FrankDenneman) and I delivered the VMworld 2012 session INF-VSP1683 VMware vSphere Cluster Resource Pools Best Practices. Here we discussed various design consideration when using or architecting the foundation of solid cloud environments. Here we got in to details and gotchas about the use of resource pools and functionalities as they related to resource allocation models. The information delivered was extremely important as the building block for vCloud Director Allocation models is based on vSphere Resource pools. This session was nominated as one of VMworld’s 2012 Top 10 sessions.
Another key session on this topic was one delivered by Chris Colotti (@ccolotti) and myself, OPS-CSM1167 Architecting for VMware vCloud Allocation Models. In this session Chris and I discussed the details of the three different allocation models of vCloud Director and explained the affect they have on the vSphere resource scheduling. We talked about and demonstrated examples of use cases for the different allocation models and how to use them. The main goal was to basically demonstrate that by having a solid understanding of the vSphere resource allocation, the logic, understanding and use of vCloud allocation models would be simplified and much easier to understand.
Well… for those unlucky ones that missed out on VMworld 2012 and missed the sessions don’t worry we got you covered. Some of the content that was the basis for the two presentations mentioned above was just published VMware vCloud Director Resource Allocation Models. I got the opportunity to review the document and If you follow me on Twitter, you may have seen my tweet about it how exited I was about this paper coming out about two months ago. Frank and Chris did an excellent job with the paper. The way the content and illustrations are delivered tie everything together from the vSphere resource allocation to the vCloud Director allocation model perspective, and how all of that affects VMware HA. The white paper is based on vCloud Director 1.5 but all of the content and information it’s still relevant to vCloud Director 5.1.
This is a document that I would recommend for all vCloud Director architects, and vCloud Director administrators to read, and consume completely. Go Big!
