Why View Planner

9. 99
Custom Applications Thoughts – ISV Perspective
Automate my fat client
application (which
tool should I use)?
Application SLA versus
Number of Users?
How do I simulate
PCoIP sessions?
How will I simulate end
user devices (e.g.
Speech Mic) in virtual
environment?
As part of BYOD programme, Customer adopted VMware Horizon View
As an ISV, how do I address:
- My Applications User Experience (SLA)
- Desktop Consolidation and Sizing

10. 1010
VMware View Planner
 VMware View Planner is a next generation VDI
workload generator and sizing tool that enables
each of these use cases
 Custom applications including ISV
 Platform characterization (CPU, Memory, Storage)
 Evaluate user experience
 Understand scaling issues and identify bottlenecks

View Planner Results Analysis
 Resource Utilization Measurement
• Collect “esxtop” data in batch mode
• CPU utilization
• Memory utilization
• Disk utilization
• vCenter performance chart
• vCenter Operations Manager
 Response Time Measurement (Application SLA)
• Use View Planner “Operational Latency”
• Use Custom Timer Functions

View Planner Best Practices

19. 1919
View Planner Workload – Best Practices
 Write script instead of record and play
 Provision View Desktop pool (floating) using VMware View
Administrator web interface
 Use VMware View Storage Accelerator (VSA) feature to reduce the
IOPS during boot storm
 Collect compute/resource utilization data of desktops using
“esxtop” utility in batch mode.
 Control boot storm for low-end storage with View Planner settings
 For passive mode tests
• Size the virtual client VM to run 3 – 4 View Desktop sessions
• As a rule of thumb, 1 View Desktop session consumes around ~400 MB
of memory in client VM per PCoIP session

Epic Hyperspace Client

22. 2222
Epic Hyperspace
 Epic Hyperspace is the single application framework that allows
role-based access to all of a user’s appropriate Epic functionality in
one place. It is used by staff across the enterprise – physicians,
nurses, radiologists, billing staff, etc. – as a common entry point to
the single Epic system.
 Epic Hyperspace Client (.NET and VB6) application UI is used by
physician, clinician to access data from Epic database.
 AutoIT in combination to Native application APIs and
windows/control commands used to prepare the script to test Epic
Hyperspace client application.

Nuance Dragon
Medical Practice Edition

28. 2828
Nuance Dragon Medical Practice Edition
 Most widely used and successful speech recognition solution
in medical practices
 Clinicians document “in their own words”
 Doctors can record their observation using speech mic while
seeing the patient

29. 2929
Nuance Medical Practice Edition Dictation on VMware View
 Objective was to measure Dragon Medical speech
recognition engine performance when the View Desktop
environment is saturated
 Virtual Audio Cable (VAC) software is installed in View Desktop
for simulating Speech Mic II operation
 AutoIT is used to automate the workload
Speech Mic Connected

Dragon Medical Practice Edition Dictation Experience
 35 line of text including medical terminology needed to describe the medical
condition of a patient. View Planner “operational latency” value is measured for
“Dragon - Dictate” function.
 “Dragon – Dictate” is the core function used to measure. Key was dictation time
should not degrade while we scale users.
One User
Twenty Four User

32. 3232
Host Resource Utilization under Stressed Condition
 Results of stress tests where all the users (100%) dictating at the
same time. Typically in production environment; only 3-5% of the
users dictate at any given point of time.
 Host Configuration: Intel X5560 (Nehalem series) 12 core, 48 GB
of RAM.

Cerner Millennium PowerChart
and PathNet

34. 3434
Cerner Medical Solution
 Enable physicians, nurses and other authorized users to share
data and streamline processes
 Online “digital chart” displays
 Up-to-date patient information on real time
 Accurate ordering, documentation, and billing of hospital
or health system

35. 3535
Cerner Instant Access on VMware View
 Following application are automated:
• Millennium PowerChart

36. 3636
Cerner Application Response Time
 Goal was to measure application response time when host
utilization reaches a defined threshold value
 The Cerner Millennium Response Time Measurement System
(RTMS) system is used to measure response time application
 RTMS measure for single desktop:
 Virtual Desktop RTMS when scaled:
 Virtual Desktop when “vcpu” increased (1 vcpu vs. 2 vcpu)
