Best Practice #2
“Inside View
of User Sessions“
(Monitor users not just Servers)
Inside View for Every User
Identify problems only
visible from within the user
session
Provide – Real Time, in-depth, user session statistics with
Correlation and quick Search.
Benefit: Reduce service downtime; Keep users happy!
Best Practice #3
“Pro-Active Monitoring”
(Prevention is better than cure)
Pro-Active Monitoring
A critical event
was raised when
Citrix server went
down
Prevent Outages
Proactive alert sent 30
mins before the
problem occurred –
alert pertained to
user’s memory usage
Benefit: Prevent problems from impacting users!
Best Practice #4
“Monitoring of Capacity
& Configuration Changes”
(Changes and Bottlenecks)
5. Correlating Performance and Configuration
Track Configuration Changes
Correlate performance with configuration changes
PERFORMANCE ALERTS
CONFIGURATION CHANGE
Benefit: Saves endless hours of troubleshooting
6. Historical Reports on Users, Not VMs
Understand Usage Patterns
Find out who the top users are
Benefit: Know usage patterns, trends for effective capacity planning
5. Correlating Performance and Configuration
Find Your Bottlenecks
Benefit: Right size your environment for better ROI
I/O issues – ESX Impact
I/O issues – Storage Bottleneck
Benefit: Right size your environment for better ROI

Best Practice Approach
1. 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-toend 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

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

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
–

Storage Requirements with PVS
 4-12 XenApp VMs per
physical server
 Most common Write-Cache
size 16-20GB
 8 IOPS per user for “heavy
users”
