Virtual Desktop Infrastructure design challenges

Organizations face many challenges when designing a Virtual Desktop Infrastructure (VDI) that

can absorb the bursts of input/output (I/O) users place on a network. The act of centralizing users

also centralizes the workload of those users. Centralized user workloads tend to be very dynamic,

yet somewhat coordinated in nature. This is because the highly volatile workload of thousands of

virtual desktop images can cause periodic performance issues.

A flawed design plan can lead to periods of erratic and unpredictable virtual desktop

performance. Users can adapt to slow performance, however, unpredictable performance is sure

to quickly frustrate them. A well thought-out design and implementation plan is critical to

building a successful environment that provides predictable performance within a VDI

infrastructure.

A well thought-out design and implementation plan:

♦ Has enterprise-wide, departmental agreement on the design, test, validation, and user

acceptance plans.

♦ Can handle the I/O load from the clients without causing excessive increases in the response

time as measured by the user.

Figure 1 shows resource utilization of a typical server and a VDI workload.

Figure 1 VDI workload – Example

In small-to-medium size VDI deployments, most of the issues are about the client experience and

total cost of ownership (TCO) of the solution. However, in large scale deployments storage

scaling is the primary issue that prevents production implementations. This is because

deployments with thousands of VDI images on a single array synchronous I/O spikes from all the

virtual desktops can potentially cause performance issues.
