Qsan Super Capacitor Module+ Flash

With a 16GB SLC NAND flash and super capacitor backup, this module ensures every byte of DRAM cache data is safely written to non-volatile storage during a power loss, eliminating data corruption risks. The Qsan Super Capacitor Module+ Flash is a dedicated flash backup module (FBM) engineered for Qsan XCubeSAN series storage systems, including XS3200, XS5200, and XS7200 models. It provides robust power loss protection (PLP) by combining a high-cycle super capacitor with industrial-grade SLC NAND flash, guaranteeing data integrity even in the event of an unexpected power failure.

Overview

Data centers and enterprises rely on uninterrupted data availability. This module acts as a critical safeguard for cached write operations, ensuring that data in transit is not lost when power is interrupted. The super capacitor provides immediate energy to sustain the system long enough for the DRAM cache contents to be flushed to the onboard SLC NAND flash. Once power is restored, the data can be recovered seamlessly, maintaining consistency and preventing silent data corruption.
