Storage Class Memory Workload Study - overview

This project studies performance measurement of a recent all-Phase Change Memory Solid State Device prototype and creates cost performance model using real-world workload profiles. The project explores two typical storage use-cases: storage tiering and caching. For tiering, we model a hypothetical storage system that consists of flash, HDD, and PCM to identify the combinations of device types that offer the best performance within cost constraints. For caching, we study whether PCM can improve performance compared to flash in terms of aggregated I/O time and read latency. Our aim is to analyze the feasibility and commercialization opportunity of PCM devices in enterprise storage environment.
