The PowerStore inline data reduction feature provides maximum space savings by combining both software data deduplication and hardware compression. Data reduction is always active and works seamlessly in the background with PowerStore. MongoDB also includes several compression options to help reduce the amount of space that is consumed by the operating system.
This section reviews the compression options that MongoDB offers and explains the effects of combining PowerStore data reduction with MongoDB compression. A test environment was set up on a PowerStore X model to run a series of tests with the different MongoDB compressions. Both logical and physical space consumptions were recorded and compared.
