Capacity Management Defined
What is Capacity Management? The discipline that
ensures IT infrastructure is used in the most
efficient and cost-effective manner providing
the right capacity at the right time, to meet
current and future business needs
Balancing business demand with IT supply
4
What Were Hearing
Visibility into Available Capacity

• How many more VMs will fit in my current VI?
• What is my historical capacity utilization?

• Are my VMs sized correctly?
• Can I reclaim over-provisioned or unused capacity?

Efficient Use of Existing Capacity
Ability to Predict Future Needs

• When will I run out of capacity?
• What if I add, remove, reconfigure capacity?

5
Capacity Decisions Throughout the VM Lifecycle
6
Key Considerations Resource Dependencies

• VM depends on all 4 resources (CPU, Memory, Disk,
  Network)
• Multiple servers per cluster
• Shared storage
• Multiple VMs/ LUN
• Multiple VMs/ IO path

7
Key Considerations Workload Mobility

• Workloads shift
• VMotion / Storage VMotion
• VMware DRS
• VMware HA
• Workloads grow
• Workloads get added and removed

8
Key Considerations CPU Memory Optimizations

• CPU Optimizations
• Virtual SMP Scheduling
• VMware DRS Shares and Limits
• Memory Optimizations
• Memory Ballooning
• Transparent Page Sharing
• Swapping

Key Considerations Storage Optimizations

Capacity Management Methods

• Rule of Thumb
• Guesstimates
• Tacit knowledge

It worked for me in the past

• Subjective to experiential bias
• Overly conservative to be safe

To be safe, Ill add an x buffer

• Homegrown Solution
• Excel spreadsheet
• SQL / Perl script

• Time-consuming to build, maintain, prepare and
  analyze
• Static snapshot in time

• Purpose-Built Tool
• Off-the-shelf software
• Best of breed expertise

• Automated and continuous capacity intelligence
• Enables informed, real-time decision-making

VMware vCenter CapacityIQ

• Capacity management solution for VMware vCenter,
  enabling users to analyze, forecast, and plan
  capacity needs of their virtual datacenter
• Benefits
• Deliver the right capacity at the right time
• Make informed planning, purchasing, and
  provisioning decisions
• Enable capacity to be utilized most efficiently
  and cost-effectively
• Key Features
• Perform What-If impact analysis to model effect
  of capacity changes
• Identify and reclaim unused capacity
• Forecast timing of capacity shortfalls and needs

VM Profiling

• Analysis of VM behavior and resource demands
• Accounts for
• CPU, Memory, Storage, Network
• Peak and average resource demand over time
• Basis for capacity estimates

Virtual Machine Basic Unit of Capacity
Consumption
16
VM Profiling Examples

• Idle Capacity
• Idle VMsVM has consistently low resource
  utilization over a long period of time
• Powered-Off VMsVM has been powered off over a
  long period of time
• VM Sizing Opportunities
• Over-Allocated VMsVM has been allocated more
  capacity than it needs
• Under-Allocated VMsVM needs more capacity than
  it has been allocated

17
Capacity Modeling

• Impact analysis of capacity changes
• Based on
• What-If modeling scenarios simulated set of
  changes in capacity demand or supply
• Historical resource trends
• Virtualization-awareness
• Recognizes VMware HA- and DRS-enabled clusters,
  and factors those into the predictions

???
What if I add more VMs? Is there enough capacity?
18
Capacity Dashboard

• Simple at-a-glance view into current and future
  capacity states
• Integrated into VMware vCenter
• User-tunable global settings
