6 Best Practices
Each of the component layers in the system stack shown in Figure 14 requires careful design and
configuration to ensure optimal system performance.
Figure 14: Component Stack
Within each layer of the stack you must consider each of the following design goals:
Availability Ensuring high availability is a critical design guideline for each component in
the solution. Redundant sub-components and connection paths must be
maintained to avoid single points of failure.
Scalability Scalability is also critical design goal. Your solution architecture should be
able to scale to meet performance and capacity needs.
Performance Performance of each component in the stack must be balanced such that all
performance requirements for the VDI system are met (examples: I/O latency,
user response times).
We present a top-down discussion summarizing design and configuration best practices related to
each of the layers in the component stack in the following sections.
6.1 Application Layer
There are many considerations at the application layer that you need to focus on.
User Data Considerations
We recommend that you do not store user data in the virtual desktop’s local drive. Separate file servers
should be used for storing user data. Specifically, group policies should be used to configure a user’s
virtual desktop profile to leverage roaming user profiles and folder redirection. Roaming profiles allow
