Test tools
To facilitate the placement and management of simulated loads on an HP SBC server, HP used
Terminal Services Scalability Planning Tools (TSScaling), a suite of tools developed by Microsoft to
help organizations with Microsoft Windows® Server 2003 Terminal Server capacity planning.
Table 1 describes these tools.

User profiles
To simulate typical workloads in this environment, HP used scripts based on the Heavy, Medium, and
Light User profiles described in Table 2.

. User profiles incorporated into the test scripts
User class
Activities
Heavy User
Heavy Users (also known as Structured Task Workers) tend to open multiple applications
simultaneously and remain active for long periods. Heavy Users often leave applications open
when not in use.
Medium User
Medium Users (also known as Knowledge Workers) are defined as users who gather, add value
to, and communicate information in a decision-support process. Cost of downtime is variable but
highly visible. These resources are driven by projects and ad-hoc needs towards flexible tasks.
These workers make their own decisions on what to work on and how to accomplish the task.
Sample tasks include: marketing, project management, sales, desktop publishing, decision
support, data mining, financial analysis, executive and supervisory management, design, and
authoring.
Light User
Light Users (also known as Data Entry Workers) input data into computer systems. Activities
include transcription, typing, order entry, clerical work and manufacturing.
