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.

Relationship between requirements and

equivalent reference virtual desktops

CPU

Equivalent reference virtual desktops =

Resource requirements

Memory

Equivalent reference virtual desktops =

(Resource requirements)/2

IOPS

Equivalent reference virtual desktops =

(Resource requirements)/10

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.
