5. Sizing your environment Hyper-V Guests Guest Processor: 4 Cores Memory: 8GB Disks: 2-C: Network: 1GB Guest Processor: 12 Cores Memory: 32 GB Disks: 2-C: 4-D: Network: 1GB Guest Processor: 8Cores Memory: 16 GB Disks: 2-C: 2-D: Network: 1GB

6. Sizing your environment Hyper-V Guests • Used for Lync Roles: • Front ends • Back Ends • Standard Edition Guest Processor: 12 Cores Memory: 32 GB Disks: 2-C: 4-D: Network: 1GB Hardware Requirements: http://technet.microsoft.com/en-us/library/gg398835.aspx

7. Sizing your environment Hyper-V Guests Guest Processor: 8Cores Memory: 16 GB Disks: 2-C: 2-D: Network: 1GB • Used for Lync Roles: • Edge Servers • Directors Hardware Requirements: http://technet.microsoft.com/en-us/library/gg398835.aspx

8. Sizing your environment Hyper-V Guests Guest Processor: 4 Cores Memory: 8GB Disks: 2-C: Network: 1GB • Used for Lync Roles: • Stress Agents Hardware Requirements: http://technet.microsoft.com/en-us/library/gg679084.aspx

9. Sizing your environment Scaling the roles • On the server side Frontends scale the fastest • 3,333 Users / Front End Front End Back End Edge Server Stress Agent

10. Sizing your environment Scaling the roles • The backend will scale with Pool count. • 40,000 Users / Lync Pool Front End Back End Edge Server Stress Agent

11. Sizing your environment Scaling the roles • The edge server will scale with Pool count. • 40,000 Users / Lync Pool Front End Back End Edge Server Stress Agent

12. Sizing your environment Scaling the roles • The stress agents will scale the fastest • 4,500 Users / Agent Front End Back End Edge Server Stress Agent

13. Hyper-V Configuration Notes Processor CPU ratio must be 1:1 Do not use oversubscription of processor cores Memory Do not use Dynamic memory for servers running Lync Network Dedicate a physical adapter to Lync Server Use Synthetic Adapters Disk Dedicated disk arrays for virtual machines Use fixed virtual disks

14. Stress Tooling User Provisioning Tool • Create users and groups • Enable users for Lync • Generate contact lists • Create test location info.

15. Stress Tooling User Provisioning Tool Changing “Average Contacts per User” will increase subscriptions per user and increase processor utilization on the Lync Frontends.

16. Stress Tooling Lync Load Configuration Tool • Specify Stress Agents • Service discovery • Enable Modalities to test • Set load variables such as number and frequency of PSTN calls

17. Stress Tooling Lync 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.

19. Testing

20. Testing Methodology Verify your environment is functional Run tests for 24 hours Run the tests twice Use control clients

21. Running Tests Lync Load Configuration Tool • Once desired configuration determined Generate files • Directory created for each stress agent • Each directory should be copied the corresponding agent

22. Running Tests Lync Performance and stress tool • Runs all the tool generated tests • Runs a specific test such as instant messaging

23. Performance Monitoring Key Health Indicators • 2 categories, service & resource instrumentation • Add to performance collections • Analyze to determine services are in a healthy state

24. Performance Monitoring Performance Counters • Actual Counter Names • LS:DATAMCU - MCU Health And Performance\DATAMCU - MCU Health State • LS:AVMCU - MCU Health And Performance\AVMCU - MCU Health State • LS:AsMcu - MCU Health And Performance\ASMCU - MCU Health State • LS:ImMcu - MCU Health And Performance\IMMCU - MCU Health State

25. Summary Hyper-V Guest requirements and recommendations Scaling units for different Lync roles Stress Tools Provisioning test users Configuring the user profiles Running stress tests Performance Monitoring Key Health Indicators Performance counters
