Explanation:
For a PowerFlex system that requires compression, the necessary components include NVDIMMs and a storage pool with fine granularity. Here’s why these two components are required:
NVDIMMs: Non-Volatile Dual In-line Memory Modules (NVDIMMs) provide high-speed DRAM performance coupled with flash-backed persistent storage. They are used specifically for compression on PowerFlex storage-only nodes. At least two NVDIMMs per server are required if storage compression is active1.
Fine Granularity Storage Pool: Inline compression in PowerFlex is enabled when using the fine-granularity data layout for storage pools. This granularity level allows for more efficient data compression and storage optimization2.
These components work together to enable compression in the PowerFlex system, ensuring efficient storage utilization and performance. The use of NVDIMMs for compression enhances the system’s ability to handle the additional workload associated with compressing data, while the fine granularity storage pool provides the necessary structure for data layout that supports compression12.
