What Happens When There Are Issues?
Virtualizing Application Delivery Requires Collaboration eG Innovations and Atlantis Computing are key elements
to a successful, cost-effective XenApp Solution:
– Reduce the cost & complexity – Deliver on the ROI and user experience promise of

“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
I/O issues – Storage Bottleneck

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
