Virtualization Performance

Dan KusnetzkyDistinguished AnalystKusnetzky Group [email protected]

• Rapid change• Increasing use of

virtualization technology• Emergence of cloud

computing• Need to reduce costs at

any cost• Maintain established

systems

What is the problem?

Kusnetzky Group, LLC © 2012

• 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?

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

Where is the Problem?

• 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

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


• 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

What would an ideal tool look like?


1. Virtualization makes performance management easier2. Resource reservation ensures that VMs don’t interfere

with each other3. Virtualization is just another silo that can be managed

independently from other tiers4. Virtualization platforms already include all tools and metrics

needed to manage the virtual layer5. The hypervisor view of virtual machines is sufficient

to manage VMs6. VDI performance management can be done using tools

that support Virtual Servers7. Scaling is linear - more hardware means more performance

7 Myths - Fact or Fiction?



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


Virtualization Performance Management

Bala VaidhinathanCTOeG [email protected]


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

Physical Virtual


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

Disk reads

Streaming Media AppSlow Database Queries

Excessive disk reads by the one VM slows down application within another VM

Shared resources become bottlenecks:• Network• Storage• Compute• Apps• Desktop


Myth #3 “Virtualization is just another silo that can be managed independently fromother tiers”

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

Myth #5 “The hypervisor view of virtualmachines is sufficient to manage VMs”

• The Outside view shows the portion of physical resources used by each VM (CPU, disk, memory)

• Provided by the virtualization hypervisor

• Useful for capacity planning and identifying certain VM issues

• Does NOT show why a VM is consuming resources

Apps inside a VM

• The Inside view shows the portion of resources allocated to a VM that are used by each application and each user of the VM

• Provided by the guest OS (for Windows: WMI)

• Useful for user load balancing, identifying guest OS issues, misbehaving applications, and unauthorized user activities

• Does show why a VM is consuming resources, accelerates fix


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

Performance management for VDI is extremely unique as you need a solution that

combines multiple different performance management

methodologies

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
