Why View Planner

9 9

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 10

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

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 19

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 22

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 28

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 29

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

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 32

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 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:
