Hyper-V Configuration NotesProcessorCPU ratio must be 1:1Do not use oversubscription of processor cores

MemoryDo not use Dynamic memory for servers running Lync

NetworkDedicate a physical adapter to Lync ServerUse Synthetic Adapters

DiskDedicated disk arrays for virtual machinesUse fixed virtual disks

Stress ToolingUser Provisioning Tool

• Create users and groups

• Enable users for Lync• Generate contact lists• Create test location

info.

Stress ToolingUser Provisioning Tool

Changing “Average Contacts per User” will increase subscriptions per user and increase processor utilization on the Lync Frontends.

Stress ToolingLync Load Configuration Tool

• Specify Stress Agents• Service discovery• Enable Modalities to

test• Set load variables such

as number and frequency of PSTN calls

Stress ToolingLync Load Configuration Tool

Be mindful of the features you enabled and how you configure them. For instance the Reach client can increase processor utilization on the Frontends.

Testing

Testing MethodologyVerify your environment is functionalRun tests for 24 hoursRun the tests twiceUse control clients

Running TestsLync Load Configuration Tool

• Once desired configuration determined Generate files

• Directory created for each stress agent

• Each directory should be copied the corresponding agent

Running TestsLync Performance and stress tool

• Runs all the tool generated tests

• Runs a specific test such as instant messaging
