VMware vSphere Performance – Part One: Optimizing ESXi Host Memory

January 16, 2015

Once you have have assessed the hardware requirements for ESXi host systems (requires a minimum of 2GB to install) to ensure sufficient memory resources are provided to satisfy the demand of the virtual machines, system overhead and the level of failure protection required, we shall look at various options for optimising ESXi host system memory. … More VMware vSphere Performance – Part One: Optimizing ESXi Host Memory

Automating the simulation of random memory workloads using TestLimit utility with Powershell

March 8, 2014

I was recently looking at simulating memory usage across a number of VMs where the utilisation pattern, time duration of the memory load and idle time between workloads would be random. I was looking at using the Sysinternals TestLimt utility to achieve this by invoking a leak and touch memory to simulate resource usage. As I … More Automating the simulation of random memory workloads using TestLimit utility with Powershell
