workload separation, purchase additional disk drives for each group that
needs workload isolation and add them to a dedicated pool.
It is not appropriate to reduce the size of the main storage resource pool in
order to support isolation or to reduce the capability of the pool without
additional guidance beyond this paper. The storage layouts presented in
the solutions are designed to balance many different factors in terms of
high availability, performance, and data protection. Changing the
components of the pool can have significant and difficult-to-predict
impacts on other areas of the system.
Server resources
For the server resources in the VSPEX end-user computing solution, it is
possible to customize the hardware resources more effectively. To do this,
first total the resource requirements for the server components as shown in
Table 21. Note the addition of the “Total CPU Resources” and “Total
Memory Resources” columns at the right of the table.

In this example, the target architecture required 700 virtual CPUs and 1,800
GB of memory. With the stated assumptions of 8 desktops per physical
processor core and no memory over-provisioning, this translates to 88
physical processor cores and 1,800 GB of memory. In contrast, the 1,000
virtual desktop resource pool as documented in the solution calls for 2,000
GB of memory and at least 125 physical processor cores. In this
environment, the solution can be effectively implemented with fewer
server resources.
Note: Keep high availability requirements in mind when customizing the
resource pool hardware.
