Final Thoughts and Q&A

Disclaimer

• We shall refer to a few different storage technologies by name as examples.

• We can’t use every single storage vendor on earth for examples.

• Don’t let it harsh your mellow if we don’t use your favorite.

• Some things presented here are the opinions of the presenters

Storage for Horizon –Ten Tips

1. Don’t Gamble – Do an Assessment!

REGISTER• Fill out a short form for access to your personal dashboard

• Cloud-based back-end is automatically provisioned for you1

RUN

• Download our simple agent and run it to gather the necessary data

from your environment

• The dashboard keeps you up to date on the progress of your assessment2

REPORT

• Access personalized reports to review your environment’s readiness

and your infrastructure requirements

• Gain visibility into the costs associated with your Horizon environment

3. The Thing about IOPs

Virtual Disk IO – It’s Mostly about Latency

ApplicationGuest OS

ESX Storage

3. KAVG

2. DAVG

1. GAVG

QAVG

GAVG = KAVG + DAVG

Fabric

vSCSI

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

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 for Horizon View.

8. Formulas, Formulas, Formulas

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

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

Space Performance

9. Rules of Thumb

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

AFA CONSIDERATIONSPerformance

• 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

PERFORMANCE VALIDATION

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

Call to Action

Perform an assessment

Beware of rules of thumb

Focus on the latency

Take risks with new storage technologies

Know your use cases

Consider SPAMS

Have fun!
