ScaleFlux Launches PCIe Gen6 SSD and CXL 3.2 Controllers
ScaleFlux has unveiled two next-generation silicon platforms at Future of Memory and Storage (FMS) 2026, targeting the rapidly increasing bandwidth, capacity, and power-efficiency requirements of AI, hyperscale cloud, and enterprise infrastructure.
The new FC6116 PCIe Gen6 NVMe SSD Controller and MC600 PCIe Gen6 CXL 3.2 Type 3 Memory Controller extend ScaleFlux’s storage and memory portfolio into the PCIe Gen6 era.
The two controllers address complementary parts of the infrastructure stack. The FC6116 targets high-performance NVMe storage, while the MC600 enables CXL-based memory expansion and pooling. Both emphasize bandwidth efficiency, power optimization, security, and flexible deployment.
ScaleFlux is also positioning the products as turnkey platforms rather than standalone silicon, providing production-ready firmware, validated reference designs, and contract-manufacturing partner support intended to reduce development and qualification time.
🚀 FC6116 Brings 28 GB/s PCIe Gen6 Storage Performance #
The FC6116 is ScaleFlux’s flagship PCIe Gen6 NVMe SSD controller, designed for AI clusters, hyperscale data centers, enterprise storage, and cloud infrastructure.
The controller supports both PCIe Gen6 x4 and dual-port 2x2 configurations. In its Gen6 x4 configuration, ScaleFlux claims performance that effectively saturates the available PCIe interface.
Key specifications include:
- Up to 28 GB/s sequential read throughput
- Up to 25 GB/s sequential write throughput
- Up to 7 million 4 KB random-read IOPS
- More than 1 million sustained 4 KB random-write IOPS
- Less than 9 W active controller power
- Support for TLC, QLC, and SLC NAND
- Storage capacities up to 256 TB
The combination of high throughput and sub-9 W controller power is particularly relevant to AI storage systems, where increasing bandwidth without proportionally increasing power consumption is becoming a critical design constraint.
Broad NAND and Form-Factor Support #
The FC6116 supports major EDSFF form factors, including E1.S, E1.L, E3.S, E3.L, as well as U.2/U.3 configurations.
ScaleFlux also provides a turnkey Arm-based firmware platform designed to accelerate SSD development while retaining flexibility for customer-specific customization.
For large-scale AI deployments, this approach can reduce the engineering effort required to integrate the controller, firmware, NAND, and physical SSD platform into production systems.
Security and Data Integrity #
The FC6116 includes a broad set of security capabilities designed for enterprise and data-center environments.
Security features include:
- PCIe Integrity and Data Encryption (IDE)
- OCP Caliptra 2.0 compliance
- CNSA 2.0 post-quantum cryptography
- S.A.F.E. security framework support
- Firmware attestation
- TCG Opal 2.0
The controller also incorporates enterprise reliability mechanisms such as full power-loss protection, end-to-end data-path protection, advanced LDPC error correction, and compliance with the OCP Datacenter NVMe SSD Specification.
ScaleFlux plans to begin FC6116 sampling with key customers in Q4 2026.
🧠MC600 Targets PCIe Gen6 CXL Memory Expansion #
The second major product is the MC600, a PCIe Gen6 CXL 3.2 Type 3 Memory Controller designed for memory expansion and pooling in next-generation servers and AI infrastructure.
The controller is built around a PCIe Gen6 physical layer and complies with the CXL 3.2 specification.
ScaleFlux claims typical power consumption below 9 W in a PCIe Gen6 x8 configuration, giving system designers a way to add substantial memory capacity without creating a disproportionate increase in platform power or cooling requirements.
This is particularly important for hyperscale infrastructure, where memory capacity and memory bandwidth are increasingly constrained by both power budgets and physical server limitations.
DDR4 and DDR5 Support in One Controller #
One of the MC600’s most notable features is support for both DDR4 and DDR5 memory architectures.
The controller integrates:
- A quad-channel architecture supporting dual-channel DDR5
- 40-bit DDR5 channels with 2DPC support
- Dual-channel DDR4 support with 72-bit channels
- 2DPC support for DDR4
- RDIMM and UDIMM compatibility
- Up to 2 TB of DDR5 memory
Supporting both generations allows infrastructure operators to reuse existing DDR4 memory resources while transitioning toward newer CXL-based memory architectures.
For data-center operators, this compatibility can reduce migration costs and extend the useful life of deployed memory assets instead of forcing an immediate transition to an entirely new memory ecosystem.
Flexible CXL Deployment Options #
The MC600 supports several physical deployment models, including:
- PCIe add-in cards (AICs)
- EDSFF E3.S 1T
- EDSFF E3.S 2T
- Custom form factors
This flexibility allows the controller to be incorporated into different server, AI accelerator, storage, and edge-computing architectures.
As CXL becomes increasingly important for separating memory capacity from individual CPU sockets, flexible physical implementations can help system designers integrate memory expansion according to the requirements of different server platforms.
🔒 Security Is Built Into Both Platforms #
Security is a common design focus across the FC6116 and MC600.
The MC600 includes PCIe IDE, OCP Caliptra 2.0 compliance, S.A.F.E. security framework support, and firmware attestation.
Together with the FC6116’s broader storage-security feature set, the platforms are designed to address security requirements that extend beyond basic device authentication and into the integrity of firmware, data paths, and PCIe communications.
For AI and hyperscale deployments, this is increasingly important because storage and memory devices are becoming tightly integrated into distributed infrastructure rather than functioning as isolated peripherals.
âš¡ PCIe Gen6 and CXL Push Infrastructure Efficiency Forward #
The FC6116 and MC600 address two complementary bottlenecks emerging in modern AI and cloud infrastructure: high-speed storage and scalable memory capacity.
The FC6116 uses PCIe Gen6 bandwidth to deliver up to 28 GB/s of sequential read performance while maintaining controller power below 9 W. The MC600 similarly targets efficient memory expansion through CXL 3.2 while supporting up to 2 TB of DDR5 memory.
The combination reflects a broader infrastructure trend in which performance alone is no longer sufficient. AI systems increasingly require higher bandwidth per watt, greater memory density, flexible resource allocation, and stronger device-level security.
By providing production-ready firmware, reference designs, and manufacturing support alongside the silicon, ScaleFlux is also attempting to shorten the path from controller adoption to production hardware.
Both the FC6116 and MC600 are scheduled to begin sampling with key customers in Q4 2026, marking ScaleFlux’s entry into the next generation of PCIe Gen6 storage and CXL 3.2 memory infrastructure.
