Overview
The ScaleFlux FC6116 is a flagship PCIe Gen6 NVMe SSD controller purpose-built for AI, hyperscale, enterprise and cloud storage deployments. It supports both PCIe Gen6 x4 and dual-port 2x2 configurations, doubling the bandwidth class of the previous PCIe Gen5 generation so more KV-cache and context data can move between high-bandwidth memory and flash.
For infrastructure buyers the differentiators are the security and reliability blocks: PCIe Integrity and Data Encryption (IDE) on the link, OCP Caliptra 2.0 root-of-trust compliance with firmware attestation, CNSA 2.0 post-quantum cryptography and TCG Opal 2.0. Enterprise-class features include full power-loss protection, end-to-end data path protection and advanced LDPC error correction, in line with the OCP Datacenter NVMe SSD specification.
ScaleFlux introduced the FC6116 alongside its MC600 CXL memory controller at FMS 2026, targeting the storage tier that sits between GPU HBM and networked storage in AI factories. QS Compute supplies Gen6-class storage controllers and the SSDs built around them for AI infrastructure.
Key Benefits
PCIe Gen6 x4 / 2x2 doubles Gen5-class bandwidth for AI data paths. PCIe IDE + Caliptra 2.0 secures the drive-to-host link and firmware. CNSA 2.0 PQC future-proofs encryption. OCP-compliant for hyperscale qualification.
Applications
AI training and inference storage tiers; KV-cache and context-memory SSDs; hyperscale cloud storage; enterprise NVMe arrays; and OCP-qualified datacenter drives.
