MonTitan™, PCIe Gen5 SSD Development Platform

A high performance, user programmable PCIe Gen5 platform targeting the most challenging data center and Enterprise SSD solutions. Inspired by the OCP Data Center NVMe SSD and NVMe 2.0 specifications, MonTitan™ provides a purpose-built ASIC and FW architecture supporting user SSD Application Optimization in both NVM Express (NVMe) and Host Based FTL usage models for addressing data placement in next generation NAND.

SM8366 - High Performance 16 Channel PCIe Gen5 x4 NVMe SSD Controller

The SM8366 is MonTitan™ platform's high performance, dual ported Enterprise and Data Center PCIe Gen5 x4 NVMe controller targets the most demanding AFA, Caching, HCI, CRM, ERM and traditional DAS and RAID applications. Containing 16 channels and supporting up to 2400MT/s, the SM8366 provides industry leading blazingly fast Sequential (>14GB/s) and Random (>3.0M IOPS) SSD performance. It contains a scalable Single / Dual Channel 40bit DDR4-3200 / DDR5-4800 DRAM interface and is provided in a 21mm x21mm FCBGA package enabling a single chip and FW stack to be used across all new EDSFF form factors.


Silicon Motion's families of enterprise SSD controllers include solutions supporting standard PCIe Gen4 NVMe and SATA interfaces

Silicon Motion PCIe Gen4 NVMe controllers maximize the bandwidth of the PCIe Gen4 x4 Host interface with > 6.5GB/s sequential read and 900K sustained Random Read IOPS. Our Gen4 solution design provides physical and logical isolation in purpose-built hardware and firmware providing consistent, low latency QoS domains while enabling customers to use the latest, highest-density 3D TLC and QLC NAND Flash technologies.

Silicon Motion SATA controllers offers an ideal replacement for lower-performance HDDs while providing more predictable latency than client SSDs. Enterprise SSDs based on a Silicon Motion SATA controllers combine enterprise-level endurance, security, and performance for read-intensive and mixed workloads, while enabling users to retain existing datacenter infrastructure for the lowest possible total cost of ownership.
