Scalable Architecture – Scale-Out

The typical business or organization is seeing data growth of 30% a year which doubles data every 2.5 years.

This data growth presents challenges to IT to ensure their backup system can scale easily to support that

growth. With scale-up disk backup solutions that have a front-end server/controller architecture and add just

disk shelves as data grows, you start with a short backup window, but as data grows, the backup window

expands because only disk is added but no additional deduplication processing resources. Eventually, the

backup window expands to a point where you must replace the front-end server with a more powerful server

via a costly “forklift upgrade.”

In contrast, ExaGrid’s scalable approach with global deduplication adds full servers—including memory,

processor, and bandwidth as well as disk. The figure below shows the differences between how the two

different architectures cope with data growth over time.
