With all of the resources defined, determine an appropriate value for the
Equivalent Reference virtual desktops line by using the relationships in
Table 18. Round all values up to the closest whole number.

For example, a group of 100 users need the 2 virtual CPUs and 12 IOPS per
desktop described earlier along with 8 GB of memory on the resource
requirements line. For this example they need 2 reference desktops of CPU,
4 reference desktops of memory, and 2 reference desktops of IOPS based
on the virtual desktop characteristics in Table 18. These figures go in the
“Equivalent Reference Desktops” row as shown in Table 19. Use the
maximum value in the row to fill in the “Equivalent Reference Virtual
Desktops” column.
Multiply the number of equivalent reference virtual desktops by the
number of users to arrive at the total resource needs for that type of user.

Once the worksheet is filled out for each user type that the customer wants
to migrate into the virtual infrastructure, compute the total number of
reference virtual desktops required in the pool by computing the sum of
the Total column on the right side of the worksheet as shown in Table 20.
