The OneFS data reduction portfolio consists of an array of several features, including compression, deduplication, and small file efficiency. While these components all coexist, they are not universally supported across the full hardware platform portfolio. The following table shows which features are available on each PowerScale hardware platform:
Key:
Furthermore, these OneFS data reduction features are individually licensed and have slightly differing use cases and performance profiles:
Data Reduction Feature | Licensing Requirement |
In-line compression | No license required. |
In-line dedupe | No license required. |
SmartDedupe | Cluster-wide SmartDedupe License. |
SFSE packing | No license required. |
Data in-lining | No license required. |
The following decision tree can assist with identifying the available and appropriate data reduction features for particular cluster configurations, data sets, and workloads:
The following sections of this paper examine each of the OneFS data reduction and storage efficiency features in more detail:
Each section provides best practices and considerations and contains information about the available tools and strategies for estimating and assessing the efficiency and performance impact of each solution. The inline and post-process deduplication sections also discuss the interoperability between the two approaches.
