In an earlier post, my colleague Reid Bourdet described how we migrated our largest Cisco Unified Communications Manager (Cisco UCM) cluster to a virtual machine environment running on Cisco Unified Computing System (Cisco UCS) servers. This was the 19-node (server) Cisco UCM cluster that serves the Cisco headquarters campus in San Jose, California; and we completed the migration over a weekend.
What makes that move even more interesting is that we’re nearly done consolidating 5 separate clusters into one virtual environment, and reducing the total number of servers by a factor of four. Virtualization on the Cisco UCS hardware allows us to consolidate multiple UCM nodes on a single blade. In this post, I’ll provide more details about the scope of this migration, the results we’ve gained, and how we’ll continue migrating other Cisco UCM clusters to Cisco UCS servers around the world.
