Optimizing Hyperscale Flash Storage Innovations in Large-Capacity QLC, Host-Based FTL, Configurable Indirection Unit and Application-Optimizing Data Placement

Submitted by agustin.nika on
Hyperscale environments demand storage solutions that balance density, performance, and power efficiency—without compromising reliability. This session will explore how Pure Storage’s DirectFlash® Module (DFM) architecture and software innovations are enabling the seamless adoption of high-density QLC NAND in hyperscale deployments. We will examine how host-based Flash Translation Layer (FTL) and Pure’s DirectFlash software address the challenges of write amplification, power optimization, and drive endurance.
