16-channel PCIe 4.0 NVMe HW+ FW turnkey SSD controller

Silicon Motion launched a complete enterprise-grade 16-channel PCIe 4.0 NVMe hardware plus firmware turnkey SSD controller solution that includes a turnkey NVMe firmware stack and hardware reference design kit. The new SM8266 comes with a capacity up to 16TB with 16 NAND flash channels,and is designed to support the latest 3D TLC and QLC NAND flash technologies. The SM8266 is designed to provide consistent, low latency QoS domains.

"Our solution is the only complete PCIe Gen4 turnkey solution available today from an established merchant controller supplier," said Nelson Duann, Silicon Motion's Senior Vice President of Marketing and R&D. "Since the introduction of our PCIe Gen3 turnkey solution, we have established a longer track record of supplying turnkey solutions in terms of customer adoption and sale volume than any other company. Our Shannon Systems team is already custom designing enterprise-grade NVMe, Open-Channel and Key-Value SSDs using SM8266 for hyperscale customers' data centers with production expected in 2021."

SM8266, according to Silicon Motion is equipped with below proprietary technologies:

6th generation NANDXtend technology, which incorporates machine learning algorithms supporting Silicon Motion's proprietary high-performance LDPC error correction code (ECC) engine with RAID, ensuring better data integrity even in extreme operating environments.

End-to-end data path protection, which applies ECC to the SSD's SRAM and DRAM buffers as well as to the primary NAND flash memory array. This maintains data integrity as data is transmitted between the host and the SSD, and between buffer memories and NAND flash.
Power loss protection, which eliminates the risk of data loss in the event of an unexpected power outage.

Other features of SM8266 as shared by Silicon Motion include:

High performance PCIe Gen4 x4 & NVMe 1.4 compliance
Turnkey stacks enable standard NVMe SSD as well as proprietary Open-Channel and Key-Value SSD implementations
Support for up to 16TB of physical NAND capacity
Low and consistent latency enabled by physical and logical isolation
Ultra-high sequential read performance of up to 6.5GB/s and 950K sustained random read IOPS
Data security with AES 256-bit hardware supporting SED, Secure Boot and TCG Opal
