Vyopta Data Collector Server Sizing & Performance Considerations for Large CUCM Deployments



What is the Vyopta Data Collector server sizing & performance considerations for large CUCM deployments?


Based on our recommendations, a single Data Collector Virtual Machine (VM) should not be expected to support a call volume of more than 1,250,000 calls per day from Cisco Unified Communications Manager (CUCM).

The general recommendation is based on the following reasonable assumptions:

  • 1 CUCM Call Detail Record (CDR) is approximately 1KB in size
  • The average upload rate of 0.2MB per second from the Data Collector VM to the Vyopta Data Receiver 
  • 10MB of Call Detail Records equates to ~1,000 Call Detail Records, per minute

The operating characteristics for Data Collection are highly variable – hourly call volume distribution, network topology, bandwidth, infrastructure location, infrastructure model/type, and utilization are all factors that will affect performance. 

Note: Adding other infrastructure systems will further reduce the capacity of the Data Collector VM.
