U.2 Long Form Factor

Overview

The U.2 long form factor is Pure Storage's interim extended-U.2 drive design. It extends a standard U.2 tray to fit more NAND, reaching 300 terabytes, but is approaching the cooling limits of a PCB inside the tray. Pure positioned it as a stopgap reached during its high-capacity journey while the industry transitioned to the standardized EDSFF E2 form factor, to which Pure contributed its learnings.
