Quick assessment
An assessment of the customer environment helps to ensure that you
implement the correct VSPEX solution. This section provides an easy-to-use
worksheet to simplify the sizing calculations, and help assess the customer
environment.
First, summarize the user types planned for migration into the VSPEX End-
User Computing environment. For each group, determine the number of
virtual CPUs, the amount of memory, the required storage performance,
the required storage capacity, and the number of reference virtual
desktops required from the resource pool.
Applying the reference workload provides examples of this process.
Fill out a row in the worksheet for each application, as shown in Table 17.

Fill out the resource requirements for the User Type. The row requires inputs
on three different resources: CPU, Memory, and IOPS.
The reference virtual desktop assumes most desktop applications are
optimized for a single CPU. If one type of user requires a desktop with
multiple virtual CPUs, modify the proposed virtual desktop count to
account for the additional resources. For example, if you virtualize 100
desktops, but 20 users require 2 CPUs instead of 1, consider that your pool
needs to provide 120 virtual desktops of capability.
Memory plays a key role in ensuring application functionality and
performance. Each group of desktops will have different targets for the
available memory that is considered acceptable. Like the CPU
calculation, if a group of users requires additional memory resources,
simply adjust the number of planned desktops to accommodate the
additional resource requirements.
For example, if there are 200 desktops to be virtualized, but each one
needs 4 GB of memory instead of the 2 GB that is provided in the
reference virtual desktop, plan for 400 reference virtual desktops.
