No doubt you are familiar with the established benefits of virtualization: improved efficiency and resource availability at a lower overall cost. Many IT departments, however, have discovered that virtualizing applications can create new and unexpected performance problems. As businesses drive towards the distributed IT infrastructure model, how can you be sure that your application performance and service levels will not be sacrificed following P2V migration? Join Correlsense and Emulex for an online seminar on how your business-critical applications can survive P2V migration without a performance degradation. During this session, we will discuss: -The growing complexity of the modern IT infrastructure and the accelerating pace of change -The challenges of guaranteeing service levels before, during and after a P2V migration -The importance of end-to-end visibility in monitoring application and storage performance We will conclude with a discussion of the Correlsense and Emulex solutions plus Q&A.

4. Why Application and I/O
Performance are Crucial for P2V

5. What The Experts Are Saying …
50% “..half or more of the database time is
attributable to storage I/O”
Storage - Gartner’s Sept 2011, “Magic Quadrant for Application Performance Monitoring”
Wait Time
“It is vital to understand the value of performance for
each environment and particular application.”
“Improving [storage I/O “The cost for I/O response time needs to be part of the
completion time] will have data center cost structure.”
a dramatic effect on - IDC, ‘Data Center I/O Performance Issues and Impacts’
[application] transaction
rate and scalability.”
– Pure Storage.com (Matt Kixmoeller)
“Measuring application response time and transaction throughput is the only
way to ensure acceptable performance before, during, and after [migration] to
a virtualized or private cloud environment.” – Virtualization Practice.com (Bernd Harzog)

7. The End-to-End (E2E) Challenge
Complexity is growing in the data center
– Virtualization brings efficiency gains but complexity challenges
– Service-oriented architectures mean performance management now a
holistic undertaking
Administrators are being pressured to
– Reduce the time to deploy new applications and technologies
– Increase the number of applications and technologies supported
– Extend the performance of existing infrastructure
The challenge…
– How to manage application availability and performance SLAs?
– Domain-specific monitoring lacks holistic visibility

8. Unspoken Fear of P2V
Traditional physical hardware is predictable and dedicated
Virtual infrastructure introduces sharing, over-subscription
Application performance before migration will not match application
performance post migration.
Solutions may be out of our control as the hardware resources are not
managed by others.
There is no way to go back.

9. Why Application Owners Should Care
About storage – and Vice Versa
New storage configuration options
– Application performance enhanced by fine-tuning storage components
– Server hardware performance gains increased significance of storage
performance
– Data analytics increases reliance on robust storage performance
Application vs. Storage – “Who’s problem is it, anyway?”
Problem Application Storage
Web-site performance To many embedded objects? Static content is on a slow storage
device?
On-line app Missing index? DB lock? Bad Peak usage is causing large
performance query? storage queues, making app wait?

10. P2V Best Practices

11. Are You Ready for P2V?
Don’t start without a plan
– Identify dependencies for apps and storage
– Prioritize order of virtualization Plan
Baseline ‘real-world’ infrastructure performance
– Establish where you are now and where you
want to be Baseline
Establish robust SLAs
Create
– Measure from end user through to storage
SLAs
Early warning & continuous monitoring
– Automate SLA monitoring Monitor, R
eport, Rea
– Pro-active alerting based on dynamic performance

12. Will You Have E2E visibility When You Migrate?
Traditional tools are insufficient for end-to-end performance management

13. P2V Checklist
Assure service-levels while migrating to a virtualized environment
– e.g. under-provisioning of application nodes, over utilization of LUNs!?

14. The 5 Layers of User Frustration
Here, with pro-
active monitoring
1. User notices slow application
and ignores
2. User hounded by slow app and tries When
does IT
their own fix (e.g. refresh/restart) find out?

3. User frustrated by slow app and
&%#!'s to friend or co-worker

“monitoring”
4. Severe disruption - user

15. Tools Available That Can Help

16. Proactive Monitoring Tool Basics
Increase operational efficiency
– Avoid Application `brown-outs` and slowdowns
– Reduces staff and time to resolution
Save on hidden costs
– Fix problems before they become really expensive
– Solve more problems in L1 & L2 support not development
Types of problems you can identify quickly
– Problems with end user experience
• Instantly isolate root cause from browser, through data-
center down to the storage
– Problems with application transactions
• Quickly Isolate root cause from application and database tiers
– Problems with storage performance
• Identify Impacted Applications and Services

17. Instant Problem Isolation
Instantly isolate root cause across the entire infrastructure.
– From browser, through entire technology stack and down to the storage
Eliminate finger pointing
– War-room (blame-storming) cross discipline communication tool

Combined advantages include:
– Monitor transaction performance from client end-users, web tier, application
tier, service tier, and database tiers
– Monitor the application view of storage performance (FC and FCoE, with iSCSI
and DAS coming soon)
– Drill down into transaction data to understand the storage impact, or lack
thereof, on application performance
– Proactive SLA management of the multi-tier application layers and storage
backend they rely on
