GAVG = KAVG + DAVG
Fabric

HBA
Time in ESXi storage stack is minimal, for all practical purposes
KAVG ~= QAVG. In a well configured system QAVG should be zero
Array SP
When KAVG > 0, I/O
is typically backed up in
a device or adapter Queue

7. The Importance of Tuning

28. OS Optimization Tool (OSOT)
• What
– A standalone tool to optimize Windows OS
image for Horizon View.
• Benefit
– Improve performance and optimize infrastructure.
Reduce CPU/memory/storage/network overhead.
• How
– By disabling unnecessary services/features,
customize configurations, etc.
• Fling
– https://labs.vmware.com/flings/vmware-os-
optimization-tool
• Derived from VMware OS Optimization Guide f
or Horizon View.

8. Formulas, Formulas, Formulas

30. Calculators and Formulas
• Calculators will use rule of thumb numbers –
unless you have real numbers
• Very high tech napkin
• Great for planning, bad to solely on for
implementation
• Our PSO and Partners never rely strictly on
calculator
30

31. Space and Performance
• Always do space calculations
– Trust but verify
• Things that impact space calculations:
– Using Local SSD or PCI Flash
• Stateless Desktop for example
– Full Clones
– Linked Clones
• Persistent disks
• Disposable Disks
• Recompose frequency & SESparse
– View Storage Accelerator (CBRC)
– Memory Reservations (vswap)
• Do IOPS calculations
– Except when it doesn’t matter
• Things that impact performance:
– View Storage Accelerator (CBRC)
• Don’t overcommit server RAM!!
– Array type
– Array cache
– Storage tiering
– Storage Network
– VAAI

9. Rules of Thumb

33. Rules of Thumb
33
• You will find other rules of thumb guide numbers – that’s why they can be
dangerous…confusing…wrong
• Keep in mind these are average numbers
– Read / Write Mix
– Bursts – Boots, Provisioning. Logins, Lunar Cycles, Antivirus
– Average Numbers = Likely failure

57. AFA CONSIDERATIONS
Performance
• Modern all-flash storage
– More than just performance
• Spec sheets
– Trust … but verify!
• Perform due diligence to understand:
– Behavior of AFA under duress
– Consistency of response times
– Accuracy of reported metrics
– Real world workloads

58. PERFORMANCE VALIDATION

59. GOOD HOUSEKEEPING
1. Follow the House Rules
• Apply all best practices
2. Always clean up after yourself
• Space Reclamation
3. Safety First
• Monitoring
• DR Protection

60. Call to Action
Perform an
