Notes on 100 and 200 user VM configurations

(top)

For use only on UCS E series blades see Cisco Unity Connection on UCSE.

For more information on VMware vSphere ESXi datastore requirements for this VM configuration, refer to System Requirements document.

VMWare release 5.1 and older, requires reserving one physical core per physical server - see co-residency policy. With VMWare release 5.5 and later and Unity Connection release 10.5.2 and later while utilizing the latency sensitivity feature, you may remove the requirement of dedicated one physical core per physical server. This requires the Unity Connection VM Latency Sensitivity to be set to 'High' while at least one other VMs is set to 'Normal'. Recommend every VM to be set to 'Normal' except for Unity Connection VMs.

Limits for Standalone Configuration:

• 8 ports G.711 or G.729a (combined TUI, VUI, or TTS)
• 2 ports iLBC or G.722
• Voice mail only (No Integrated or Unified Messaging)

• 16 ports G.711 or G.729a (combined TUI, VUI, or TTS)
• 4 ports iLBC or G.722
• Voice mail only (No Integrated or Unified Messaging)

Feature	Descriptions	Minimum Software Version
Total number of Tenants supported on Unity Connection	0	N/A
Total number of concurrent video calls	0	N/A
Total number of Connection SRSV branches supported	0	N/A
