Unity Connection Cluster over Wan requirement

[J_Vansen_S]

hi All,

We are planning a cluster of WAN setup for our CUCM, UCCX, and CUCN in a BE6000.

Our setup consist of only 2 sites: Site A and Site B

We are running 1unit of BE6000 per site. So naturally Publisher on Site A and Subscriber on Site B.

We have bought roughly 250 mailbox licenses. How would i split my mailbox between the cluster?

Ultimately how much bandwidth do i need to support 250mailbox in my whole UC infra?

CUCM bandwidth req: ICCS(1.5mb) + DB sync(1.5) = 3Mbps

CCX bandwidth req = 2Mbps

CUCN = ?

in addition keep in mind that UCXN on BE6k can only go up to 48 total ports access clustered nodes, so 250 would not be an option:
