Unity Connection Cluster over WAN

[andinatech]

Hi All,

We are planning a cluster of WAN setup for our CUC.

I need to deploy 450 ports so we need two CUC of 250 ports in Active/Active configuration. Is it possible to deploy this scenario in a cluster over WAN beetwen two sites with a link with bandwitdh of 15 Mbps?.

Regards,

Jonathan Diaz

Hi Jonathan,

This is way less than the recommended bandwidth in Unity Connection design guide

https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/design/guide/10xcucdgx/10xcucdg060.html

• Depending on the number of voice messaging ports on each Unity Connection server, the path of connectivity must have the following guaranteed bandwidth with no steady-state congestion:

– For 50 voice messaging ports on each server—7 Mbps

– For 100 voice messaging ports on each server—14 Mbps

– For 150 voice messaging ports on each server—21 Mbps

– For 200 voice messaging ports on each server—28 Mbps

– For 250 voice messaging ports on each server—35 Mbps

---

Note The bandwidth numbers above are intended as guidelines to ensure proper operation of an active-active cluster with respect to synchronization traffic between the two servers. Additional conditions such as network congestion, CPU utilization, and message size may contribute to lower throughput than expected. Call-control and call-quality requirements are in addition to the guidelines above and should be calculated using the bandwidth recommendations in the applicable Cisco Unified Communications SRND
