Different Workloads, Different Markets
• Workloads– Cloud
• Traditional• Cloud workload
– Server virtualization– Desktops (VDI)
• Markets– Small/medium businesses– Large enterprises– Cloud
XenServer Meets All Virtualization Needs
EnterpriseData Center
•High performance, resilient virtualization platform
•Simple deployment and management model•Host based licensing to control CAPEX
DesktopVirtualization
•Optimized for high performance desktop workloads
•Storage optimizations to control VDI CAPEX
•Platform for IaaS and Cloud Service Providers•Powers the NetScaler SDX platform•Fully supports Software Defined Networking
Hypervisor Tools
• Tools from Citrix– XenCenter
• Management tool• Some diagnostics and monitoring
– APIs• Broad set of APIs• Very expressive• Absolutely not for everyone!
Different Workloads, Different Profiles
• Your workload’s profile will vary:– Application type– Time of day– Failures– Bottlenecks
• Affected hardware resources include:– CPU– Memory– Storage– Network
Scale Matters
• Characteristics vary between:– A single host– A pool of hosts– Multiple singleton hosts– Multiple pools
• The bottlenecks change• The trouble-shooting changes• The failure modes change
Environment Matters
• Is all your hardware the same?– Network cards– Storage arrays– CPUs– Memory– Local disks
• Are you sure?• Is this even a good idea?

Poll: Which IT Components Can You See?
• Desktop Layer• Application Layer• Hypervisor/virtualization Layer• Storage/Database Layer• Server/Networking Layer
You Need Cross-Layer Visibility
• The entire stack– Application– Virtual Machine Operating System– Hypervisor platform– Networking– Storage– Hypervisor hardware
• Complex interactions between layers
Typical Performance Management Challenges
• User experience issues• Lack of visibility across silos• Complex and/or slow issue identification• Proactive problem solving• Chasing issues that originate in other IT
domains

Finding The Root Cause of These Challenges is Critical
XenServer Provides the Platform
• But your infrastructure is more than the hypervisor– …different users– …different workloads– …different hardware– …different layers
• Your infrastructure is complex, and so are the challenges
Poll: What Are Your Biggest Performance Management Challenges?
• User experience issues• Lack of visibility across silos• Complex and/or slow issue identification• Proactive problem solving• Chasing issues that originate in other IT domains

Assuring Peak Performance of Critical Business Applications
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”
Streaming Media App
Slow Database Queries
Disk Reads
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 From
Other Tiers”

A problem in one tier can affect all the other tiers. Is it the network, database, app server, or virtualization tier?
“My application is slow!”

Management”

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 Canbe Done Using Tools that Support Virtual Servers”
Citrix XenServerMicrosoft Hyper-V
Virtualization
Desktop Brokers and
Support Systems
VDI
A 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
What does this lead to?•High business cost of downtime•Slow applications impact productivity•Poor user experience
User Frustration & Low Productivity
•Wasted resources on manual, complex, lengthy diagnosis•Requires too many experts & too many tools
RisingIT Support
Cost & Complexity
•Throwing costly hardware at problems•Oversized & inefficient environment
RisingInfrastructure Cost
•Delayed deployment & rollout•Performance issues & fire drills•Failed projects & initiatives
Project delays, cost overruns, missed
objectives
