A Principled Technologies test report 7
Cisco UCS B230 M2 Blade Server:
Uncompromised virtual desktop performance
 Microsoft Internet Explorer instance two: Navigating a Web site, maximizing,
and scrolling
 Microsoft Word (UserRead): Reading and typing text, and printing to PDF
 Bullzip: Generating a PDF
 Adobe® Reader®: Reading a PDF
 Microsoft PowerPoint®: Watching a presentation and adding a slide
 Microsoft Excel®: Reading and minimizing
 7-Zip: Saving a ZIP file
Login VSI Version 3.0 (Release 6) benchmarks user experience more effectively than
previous versions of Login VSI because its workloads and what the VSI Index measures more
accurately reflect the tasks actual users perform on their virtual desktops. Reported response
times are higher in Login VSI 3.0 than in Login VSI 2.0 and other previous versions because the
benchmark uses this heavier workload. The Login VSI benchmark mandates the minimum
acceptable response time for the testing.
The Login VSI 3.0 benchmark uses seven operations to determine the VSImax, the
maximum number of users the system can handle before suffering serious degradation in
performance. By using seven operations instead of only two, as earlier versions of Login VSI did,
Login VSI 3.0 better reflects what a user actually experiences. The seven operations are as
follows:
 Copying a new document from the document pool in the home drive
 Starting Microsoft Word
 Starting the File Open dialogue
 Starting the Search and Replace dialogue
 Starting the Print dialogue
 Starting Notepad
 Compressing the document into a ZIP file with 7-zip command line
Login VSI reports minimum, average, and maximum response times, as well as the VSI
Index average while performing the workload. The Login VSI Index average is similar to the
average response time, as it averages the maximum and minimum response times, but it
removes 2 percent from the maximum and minimum response time before calculating the
average. The response times are reported in time in milliseconds to perform the workload tasks.
The Login VSImax is the total number of virtual desktops the server can support while still
maintaining a response time of 4,000 milliseconds (4 seconds) or below, and is based on the VSI
Index average. In our testing at 175 sessions, the server still did not reach Login VSImax,
indicating that the server could handle the load with processor and storage resources to spare.
