Such a data center would instantly respond not only to production databases but to unstructured data requests, archive recalls and even backup and restore tasks. The idea is appealing, but is the all-flash data center realistic? An all-flash data center seems reasonable for several good reasons.

Second, data reduction technologies, such as deduplication and compression, work well in a flash environment because the excess performance of flash allows these processes to run with almost no noticeable impact on users and applications. The result is the typical all-flash array can benefit from a three- to five-times increase in data efficiency.
