SFX 5016

Get better utilization, efficiency and TCO out of your data infrastructure.

Building upon ScaleFlux’s innovative controller architecture, the SFX 5016 will set new benchmarks for enterprise NVMe SSD efficiency and performance, making your choice of SSD matter again.

SFX 5016 Controller Chip

In the face of increasing demands for the power in servers, racks, and data centers combined with tightening regulations on sustainability, an SSD controller that multiplies efficiency, sustainability, utilization and TCO can be a valuable tool for SSD and System designers as well as Infrastructure & Operations teams.  

The SFX 5016 stands apart from ordinary NVMe SSD controllers by integrating hardware accelerator engines directly into the system-on-chip (SoC) drive controller. These accelerator engines efficiently and transparently compress the data on Writes and decompress the data on Reads, resulting in SSD performance, latency, endurance, and economics that are up to 10x better than ordinary enterprise NVMe SSDs deliver.  Supporting up to 256TB of data storage, the SFX 5016 handles both high-performance and high-capacity designs gracefully.  

The ScaleFlux team understands that complexity kills.  They’ve designed SFX 5016 for simplicity and ease-of-use with standard NVMe drivers and standard NVMe commands.  So, there’s no rewriting applications or installing new software to use SFX 5016-based drives.  Additionally, the chip’s layout enables designers to use one controller to span across the standard form factors – from E1.S through U.2 to E3.S and larger form factors – to simplify firmware qualification and management. 

Key benefits of SFX 5016
