Building blocks for virtualization
VMware just published the second VMware Technical Journal. This winter edition contains great publications on topics like vProbes, Paravirtual vRDMA Devices, Cloud Tenant UI design process, Storage DRS and FrobOS. There is also a nice introduction by VMware’s CEO Pat Gelsinger. Simply to much to mention, I suggest you just download it… I think it is a great read and it gives an idea about some of the things VMware engineers work on.
I’ve read this several times by now, so I figured I would share it with you. Hopefully most of you will already be aware though at this point as several people blogged and tweeted about it.
The VMware Technical Journal is a new publication for the company. We are looking forward to producing future journal issues at regular intervals to highlight the R&D efforts taking place in several different areas of engineering. Our current issue includes papers related to distributed resource management, user experience monitoring, and statistics collection frameworks for virtualized environments, along with several other topics. In future issues we will highlight other areas of VMware R&D, including Cloud Application Platform and End User Computing, and research collaborations with academic partners.
All of the papers included in the tech journal can also be downloaded separately through the following links:
Worth reading believe me!
I’ve already put in the request to make these available as both mobi/epub.
A white paper which I have worked on extensively has just been published. The case study takes a design / architecture approach and lists design considerations, requirements and assumptions throughout the document. I want to thank the people who worked with me on this document: Aidan Dalgleish, Frank Denneman, Matthew Northam, Venky Deshpande and Cormac Hogan. Below you can find more details… don’t forget to download it! I made sure it was available in various formats so each and everyone of you can read it on its favorite device.
Source - Cloud Infrastructure Architecture Case Study
Description: The VMware Cloud Infrastructure Architecture Case Study Series was developed to provide an understanding of the various components of the VMware Cloud Infrastructure Suite. The goal is to explain how these components can be used in specific scenarios, which are based on real-world customer examples and therefore contain real-world requirements and constraints. The VMware Cloud Infrastructure Suite consists of five technologies that together expand the capabilities and value that customers can realize from a virtualized infrastructure. This case study focuses on vSphere 5.0 and vShield App 5.0.

I had a lot of trouble finding the vSphere 5.0 What’s New whitepapers so I figured I would list all of them as I probably wouldn’t be the only one finding it challenging to get all of these. These are useful to quickly scan what has been introduced for a specific category. I would recommend reading these as it will give you a better understanding of what is coming up!
Yes not only Chad Sakac deals with face melting ultra uber geeky cool stuff I do as well (those on twitter know what I am referring to), but unfortunately I cannot share the details on some of the stuff I am working on. I can however provide you a link which contains the papers written by the engineers on some of the stuff that might be coming up in the future. Note the “might”, there is no guarantee it will ever make it into the VMware products, but nevertheless still cool to read:

Is this all distant future? No it isn’t. For instance the paper that talks about Parda is actually what ended up as Storage I/O Control in 4.1. A couple I would recommend reading or at least that had my personal interest are:
This is the whitepaper I’ve been waiting for. By now we all know that the CPU Scheduler has changed. The only problem is that there wasn’t any official documentation about what changed and where we would benefit. Well this has changed. VMware just published a new whitepaper titled “The CPU Scheduler in VMware® ESX™ 4“.
The CPU scheduler in VMware ESX 4 is crucial to providing good performance in a consolidated environment. Since most modern processors are equipped with multiple cores per processor, systems with tens of cores running hundreds of virtual machines are common. In such a large system, allocating CPU resource efficiently and fairly is critical. In ESX 4, there are significant changes to the ESX CPU scheduler that improve performance and scalability. This paper describes these changes and their impact. This paper also provides details of the CPU scheduling algorithms in the ESX server.
I can elaborate all I want but I need you guys to read the whitepaper to understand why vSphere is performing a lot better than VI 3.5. (I will give you a hint: “cell”.)
Another whitepaper that’s definitely worth reading is “Virtual Machine Monitor Execution Modes: in VMware vSphere 4.0“.
The monitor is a thin layer that provides virtual x86 hardware to the overlying operating system. This paper contains VMware vSphere 4.0 default monitor modes chosen for many popular guests running modern x86 CPUs. While most workloads perform well under these default settings, a user may derive performance benefits by overriding the defaults. The paper examines situations where manual monitor mode configuration may be practical and provides two ways of changing the default monitor mode of the virtual machine in vSphere.
And while you arealready taking the time off to educate yourself you might also want to read the “FT Architecture and Performance” whitepaper. Definitely worth reading!
