Performance Best Practices for VMware vSphere 4.1

New whitepaper available for best performance practices.

This 60 pages free e-book applys to ESX 4.1 and ESXi 4.1.  The PDF book does not only gives you all the tweaks and advices how to configure your vSphere Infrastructure, but also it gives you some advices before you make the choice and buy your hardware. Then the CPU, memory, storage and networking best practices chapters guides you through to optimize to maximum your Virtual infrastructure running under VMware vSphere 4.1.

It's one of those PDFs to have wherever you are. For example in your Dropbox… -:) In case you don't know what Dropbox is, you can read my article about using Dropbox here and here.

There are also some information about performance improvements in vSphere 4.1 compared to vSphere 4.0. Also the vCenter Server sizing guidelines and software requirements.

You'll be able to learn about some best practices in performance monitoring, tuning and troubleshooting. And finaly there are also case studies demonstrating performance improvements in vSphere 4.1.

A quick quote from the PDF:

Memory Sizing
Carefully select the amount of memory you allocate to your virtual machines. You should allocate enough memory to hold the working set of applications you will run in the virtual machine, thus minimizing swapping, but avoid over-allocating memory. Allocating more memory than needed unnecessarily increases the virtual machine memory overhead, thus using up memory that could be used to support more virtual machines.
When possible, configure 32-bit Linux virtual machines to have no more than 896MB of memory. 32-bit Linux kernels use different techniques to map memory on systems with more than 896MB. These techniques impose additional overhead on the virtual machine monitor and can result in slightly reduced performance.
