As PFEs, one of our major roles and responsibilities is to relay best practices and “ lessons from the field .” In this post, I’ll present a method – not the only method – of how to progress through a Hyper-V infrastructure design. This is a high-level post and the content should not be considered “enough” to arrive at a suitable end-result design, but h opefully, this helps the reader along the virtualization path and will stimulate some thoughts and discussions .
Standard Utilization VM – 1 proc; 1024 GB RAM; 40 GB C:\
High Utilization VM – 2 proc; 2048 GB RAM; 60 GB C:\
Another idea is to spec each VM based on detailed measurements/requirements for each particular workload.
This can provide more optimal use of physical host server resources but can be more difficult to accomplish due to variations of server workloads and additional time to benchmark/perfmon each application
Application XYZ measured out for 1GB RAM and two Procs
Application ABC measured out at 768 MB RAM and one Proc
SCOM/SCVMM and Dynamic Memory features can help facilitate this effort more easily
Determine the number of planned VM Guests and consider future capacity needs
