In our next two topics in this series, we will cover the capacity planning related features in the MAP toolkit 7.0. For those of you who have used the server consolidation features in MAP, a few of these steps will seem familiar. There a couple of new things that you will need to perform and we will spend most of the time covering those.
There are two key problems that the MAP toolkit is trying to solve when planning for VDI and Session Virtualization. The first is how to model the performance characteristics and usage profile of a type of worker (e.g. people in your call center, information workers, task workers, people in finance). The second is how many Remote Desktop Server Virtualization or Session Hosts will you need to support one or more of those ‘desktop workloads’. Today, we will cover the first - A way to capture and model the hardware performance impact of a usage scenario.
The steps you will need to create a desktop workload model are:
A couple of things to note about gathering performance metrics for this scenario:
Once you’ve gathered an appropriate amount of performance data for the desktops you have targeted. You can now create your first entry in the Desktop Workload Library.
There are four steps to creating an entry in the Desktop Workload Library.
You can start the Desktop Workload Library Wizard from the Desktop Virtualization Summary page within the toolkit console.
The first page of the wizard allows you to create, edit and delete entries from your workload library.
I’m going to create one for the Information Worker profile in my organization and click ‘Next’.
On the next page of the wizard, I’m presented with a list of computers along with the name of their operating system, how many successful performance metric samples were collected and the 95th percentile calculations for CPU, Memory, Disk and Network utilization metrics.
I simply select the computers that I want to include in the model and click ‘Next’.
I review my selections and then click ‘Finish’ and MAP will calculate the performance profile for this set of desktops.
MAP does a couple of things when calculating the performance profile.
In the Desktop Workload Library, you will see the average and peak profiles. For display purposes, the average values are provided.
Now that we have a workload, we can determine how many servers we will need to host this workload. We will cover that in part III – coming soon.
Until then, download the MAP toolkit 7.0 and tell us what you think about this feature!
