Archiving and CDR Scalability

Office 2007

The scalability of the Archiving and CDR server depends on whether only CDRs are enabled or CDRs and archiving is enabled for the topology. The following summarizes the scalability of the Archiving and CDR Server as well as recommendations for configuration of purging of the database to achieve these scaling limits:

  • 125,000 users per Archiving and CDR server with only CDRs enabled. For optimal performance, the database should be configured to purge every seven days.
  • 65,000 users per Archiving and CDR server with both CDRs and IM archiving enabled. For optimal performance, the database should be configured to purge every three days. Additional RAM and disk I/O capacity is also required for this configuration.
