Microsoft introduced a brand new and exciting file system technology with Windows Server 2016 called ReFS or Resilient File System. Microsoft’s ReFS File System – No Longer Handicapped Especially in the realm of virtualized systems when there tends to be a tremendous amount of duplication between the server operating systems contained therein, there can potentially be HUGE space savings with deduplication. This enables a much more efficient storage system from a space perspective and prevents unnecessarily keeping extra copies of identical data on expensive storage subsystems when there is no need for that. “Deduplication is the ability to recognize and find these identical pieces of information that exist between the bits on disk and get rid of the extra copies of them.”Įxample: If you had the same identical set of files that were found in 20 different servers, you could effectively eliminate 19 copies and only keep 1 copy that could be used for all 20. When storing very similar servers, files, and other stored items, it is very probable you will have multiple bits of data that could be identical between a number of servers stored on a volume such as is found in storage backing a Hyper-V virtualized environment. Most of today’s complex storage systems store data in various chunks of data using different technologies.
However, it is an important technology feature of today’s modern storage solutions.
This can certainly be used as a buzzword among storage vendors. Most likely if you have been around storage or virtualization technologies for any length of time, you have no doubt heard about data deduplication or deduplication for short.
