What is the problem?

• Rapid change
• Increasing use of
virtualization technology
• Emergence of cloud
computing
• Need to reduce costs at
any cost
• Maintain established
systems

Today’s coping strategies

• Cross-functional tiger teams
– Everyone brings the
reports from their tools
– Put the operational data
jigsaw puzzle together
– Determine the root cause
– Determine what to do
about it
– Go and implement the
agreed upon solution
• Why isn’t this more simple?


Where is the Problem?

Active Directory
SQL
SAN
Switch

Enterprise
Client Apps
Network Web on XenApp on
ESX ZDC on VMware ESX

Profile Server

License Server

Oracle vCenter
What is the root cause of the service problem?
Network? VMware? AD? SQL? Storage? Profile Server?

Why don’t today’s established
performance tools do the job?

• Blind — tools look at details rather than the
whole picture
• Static — tools were designed for static
environments
• Slow — a holistic view has to be built one piece
at a time
• Complex/difficult — many different disciplines
must be involved
• Costly — Many organizations don’t have all of
the different types of expertise
• Fragmented — operational data is maintained
everywhere and nowhere


What would an ideal tool look like?

• Complete visibility — sees everything from the end
user to the data center
• Aware of all forms of virtualization — see into
virtual desktops, applications, systems, networks and
storage
• Auto diagnosis — constant monitoring and
predictive analysis producing automatic root cause
analysis
• Simplified — Built in intelligence to make things
simple
• Pre-emptive — Proactively identify issues before
they can turn into problems
• Cost effective — Reduce the cost of operations
• Comprehensive — Manage performance across all
silos from the end user to the data center


7 Myths - Fact or Fiction?

1. Virtualization makes performance management easier
2. Resource reservation ensures that VMs don’t interfere
with each other
3. Virtualization is just another silo that can be managed
independently from other tiers
4. Virtualization platforms already include all tools and metrics
needed to manage the virtual layer
5. The hypervisor view of virtual machines is sufficient
to manage VMs
6. VDI performance management can be done using tools
that support Virtual Servers
7. Scaling is linear - more hardware means more performance

Audience Poll
“What are your biggest
virtualization challenges?”
 Virtualization performance management is more complex

 Performance and user experience problems

 Inadequate performance management tools

 Lack of visibility into VMs and dependencies

 VM sprawl

Myth #1 “Virtualization makes
performance management easier”
 Scope for performance management remains the same
 10 servers, 30 guests => 300 virtual machines to monitor
 Higher complexity because of resource sharing across VMs
 Guests share CPU, memory, disk, network resources
 A single malfunctioning application in a guest can impact
performance of all other VMs

Myth #2 “Resource reservation ensures
that VMs don’t interfere with each other”

Slow Database Queries Streaming Media App

Shared
resources
become
bottlenecks:
• Network
• Storage
• Compute
• Apps
Disk reads • Desktop
Excessive disk reads by the one VM slows down application
within another VM


Myth #3 “Virtualization is just another silo
that can be managed independently from
other tiers”
“My
application
is slow!”

A problem in one tier can affect all the other tiers.
Is it the network, database, app server, or virtualization tier?


Myth #4 “Virtualization platforms already
include all tools and metrics needed for
performance management”
“My
application is Looks

slow!” problem either

Myth #6 “VDI performance management
can be done using tools that support Virtual

Performance management for
VDI is extremely unique as you

Myth #7 “Scaling is linear, more
hardware means more performance”

It is critical to understand the overall performance
at all levels and identify the bottlenecks
