Session D-7: New Ways to Improve SSD Management and Performance (SSDs Track)
Paper Title: Optimizing NVMe Drives for Your Applications

Paper Abstract: IBM's Zurich Research Laboratory developed SALSA (SoftwAre Log Structured Array), a flexible Flash Translation Layer that aggregates and manages a group of inexpensive SSDs. It lives up to its name by adding a bit of spice to the managed SSDs! SALSA has a robust and simple LSA which allows for efficient garbage collection and reclamation, and in doing so can provide reduce write amplification to ensure higher endurance and performance. This talk will explain how SALSA has evolved to work effectively with Zoned Namespaces.
