“Total Performance Visibility”

(Knowledge is Power)

Best Practice #1

Dashboard Indicates Service Issue

Service shows a serious problem

Drilldown to Transactions

User Impact detected

“Inside View of User Sessions“

(Monitor users not just Servers)

Best Practice #2

Provide – Real Time, in-depth, user session statistics with Correlation and quick Search.

Benefit: Reduce service downtime; Keep users happy!

Inside View for Every User

Identify problems only visible from within the user

session

“Pro-Active Monitoring”

(Prevention is better than cure)

Best Practice #3

Pro-Active Monitoring

A critical event was raised when Citrix server went

down

Prevent Outages

Benefit: Prevent problems from impacting users!

Proactive alert sent 30 mins before the

problem occurred – alert pertained to

user’s memory usage

“Monitoring of Capacity & Configuration Changes”

(Changes and Bottlenecks)

Best Practice #4

PERFORMANCE ALERTS

5. Correlating Performance and Configuration

Correlate performance with configuration changes

CONFIGURATION CHANGE

Benefit: Saves endless hours of troubleshooting

Track Configuration Changes

6. Historical Reports on Users, Not VMs

Benefit: Know usage patterns, trends for effective capacity planning

Find out who the top users are

Understand Usage Patterns

5. Correlating Performance and Configuration

Benefit: Right size your environment for better ROI

Find Your Bottlenecks

I/O issues – ESX Impact

Best Practice Approach1. Total Performance Visibility – Complete, end-to-end

service view with performance correlation 2. Inside View of User Sessions – In-depth visibility with

In-N-Out Monitoring inside each user’s desktop session

3. Pro-Active Monitoring – Auto-baseline and end-to-end correlation to fix performance problems before users get impacted

4. Monitoring of Capacity and Configuration Changes – Right-size your environment for maximum ROI and weed out changes that cause performance issues

Major Risks of Virtualizing XenApp

SAN

Storage Network

Storage Performance Bottleneck

Storage Network Bottleneck

PVS Write-Cache Storage Options Most use shared SAN/NAS storage Local disk has limited IOPS and is difficult

to maintain Local SSDs fail with write-heavy

workloads PVS servers will become a storage or

network bottleneck RAM has limited capacity

SAN/NASStorage

Where are the XenApp deployment risks?

Under-sizing of the PVS write-cache SAN/NAS introducing storage network risk

The impact: Cost overruns – can be very significant Project delays – while infrastructure is resized Unhappy users and management – CFO, CIO, CEO, etc.… leads to risk aversion and very cautious approach to project

Atlantis ILIO for Citrix XenApp Performance

– Accelerates boot/logon, provisioning, application response time

Storage Savings – 100%, No Storage! – No shared storage, local disk or SSDs required– Stores XenApp VMs/PVS write cache in-memory– Reduces RAM requirements by 90+% compared to PVS

alone

Risk Reduction – Absorbs write-cache sizing errors– Avoid network bottlenecks – No network storage traffic– No changes to XenApp images– Supports PVS or full clones
