Analyst(s): Nik Simpson

Summary

IT equipment is frequently replaced during a data center consolidation, with considerable effort put into designing a new storage infrastructure. However, it's important not to forget that the real value is in the application data. As a result, IT organizations must focus on how to consolidate data from the original data centers, based on application availability requirements and the constraints of the storage infrastructure at the consolidated data center. In this Burton Group assessment, Senior Analyst Nik Simpson examines the issues surrounding storage infrastructure and data movement during a data center consolidation.
