I have seen many VMware View environments (or Horizon View as it is called now) being under utilized which defeats the purpose of Virtualization in the first place. To have a proper utilization, resource requirements need to be calculated and the process is not as straight forward. So in this post I shall provide a high level view of the process of sizing up the infrastructure for Horizon View.
The data metrics assessment can be performed on Physical Desktops or Virtual Desktops (Migration V2V scenarios). There are four main components that we need to collect data metrics on to help size up the supporting infrastructure. Those components are: CPU, RAM, Network and Disk.
The objectives for the assessment are:
– Establish baseline for average user.
– Classify users into groups based on resource consumption.
– Identify top applications used and their resource requirements.
– Identify any potential risks to the VDI deployment.
Some of the key metrics we will be collecting and analyzing:
- CPU usage
- Memory usage
- Network throughput
- Network latency
- Disk IOPS
- Disk Read
- Disk Write
- Disk throughput
- List of most applications used
- Number of monitors
- Graphics Requirements
- 100 will use applications that require at least 8 GB RAM and 2 vCPUs and 2 monitors
- 300 users will have medium resource requirements of 3 GB RAM and 1vCPU
- 600 users will use kiosks with low resource requirements of 2 GB RAM and 1 vCPU
- Power Users: This desktop pool will be based on an image for 100 users that require 2 monitors, 8 GB RAM and 2 vCPUs.
- Knowledge Users: This desktop pool will be based on an image for 300 users that require 3 GB RAM and 1vCPU.
- Task Users: This desktop pool will be based on an image for 600 users that require 2 GB RAM and 1 vCPU
Thank you for reading.
