Explanation:

HPE GreenLake for Block Storage performs write operations caching by caching the data on DFC-hosted SSDs. The Data Fabric Controller (DFC) manages the SSDs and is responsible for optimizing the performance of the storage system by caching write operations. This approach ensures that write-intensive workloads are handled efficiently, providing lower latency and higher throughput for applications that demand fast storage performance.
