White Paper 
Geo-Redundancy for Cisco Prime Collaboration 
Assurance and Analytics 
Geo-Redundancy: Your key to Cisco Prime Collaboration Continuity 
You’ve invested in an advanced, feature-rich communications platform. And thanks to Cisco Prime
 Collaboration 
Assurance a
nd Analytics, you’re able to gather critical data from that system and diagnose service-quality issues 
before they become real problems. But even the most sophisticated platform can be affected by unexpected 
failures. Natural disasters. Power outages. They can take a system down and keep you from delivering on your 
commitments to customers. This white paper provides an overview and links to resources on how to avoid 
downtime and “disaster-proof” your communications, even in the face of catastrophic events. It all hinges on 
geographical redundancy (geo-redundancy). 
Simply put, geo-redundancy means running multiple instances of an application in geographically separate data 
centers. This practice provides application and service continuity and helps ensure that a major storm in one part of 
the country, for example, won’t shut down your operations. 
Cisco Prime Collaboration Assurance and Analytics requires geo-redundancy to prevent service failures during 
natural disasters or massive system outages such as power failures. The secret to geo-redundancy for Cisco 
Prime Collaboration Assurance and Analytics is VMware vSphere replication. 
What Is VMware vSphere Replication? 
VMware vSphere replication is a data protection and disaster recovery solution that provides host-based, 
asynchronous replication of virtual machines (VMs). It is fully integrated with VMware vCenter server and the 
VMware vSphere web client. And because it uses a cold standby approach with manual failover, it copies only 
changed blocks to the recovery site and uses very little bandwidth. vSphere replication can: 
● 
Use a “seed copy” of virtual machine data during initial synchronization 
● 
Help ensure efficient network usage by tracking changed disk areas and replicating only deltas 
You can get further details on VMware vSphere replication by visiting

System Requirements 
Cisco Prime Collaboration Assurance and Analytics itself does not require any special configuration to enable 
VMware vSphere replication. To enable the host-based replication in your virtual appliance environment, you need: 
● 
VMware vSphere replication, distributed as a 64-bit virtual appliance and packaged in the ova format 
● 
Dual-core CPU, 10-GB and 2-GB hard disks, and 4 GB of RAM 
● 
ESXi host on a VMware vCenter server (5.x or later) - this is a virtual appliance deployed using the OVF 
deployment wizard
