Cisco gains more user capacity with fewer servers by migrating to new voicemail system and new computing platform at the same time.

This case study describes how Cisco IT migrated from a Cisco Unity® voicemail solution, running on Cisco® 7800 Series Media Convergence Servers, to Cisco Unity Connection, running on Cisco Unified Computing™ System (UCS) servers. Virtualization was a factor as Cisco IT considered upgrading its Cisco Unity voicemail system to support more than 87,000 user mailboxes, take advantage of new user features, and reduce the number and costs of voicemail servers. Today, Cisco has implemented Cisco Unity Connection on 16 networked nodes, using 32 active-active virtual servers, the maximum system configuration.By migrating to Cisco Unity Connection and Cisco UCS at the same time, Cisco IT was able to simplify the upgrade process and capture cost savings, especially for server replacement. Because the Cisco Unity Connection software was installed and tested on the Cisco UCS servers before they were activated in production, a gradual, node-by-node transition was not necessary. Cisco IT and Cisco employees are now realizing several benefits from the migration to Cisco Unity Connection and Cisco UCS servers:

  • Reduced costs and operations demand with 80 percent fewer physical servers.
  • Simpler voicemail system design and management.
  • Faster and simpler migration process.
  • More effective business continuity and disaster recovery, because both servers in a pair are always active.
  • New user options for accessing and managing messages.
