Storage without compromise:
When Performance is Not Enough
Architectural Approach
Legacy Controllers Fail to Deliver and Suppliers Didn’t Care
SSDs are defined by the capability of their controllers.
High power legacy controllers, with complex FTL layers and heavy CPU subsystems, cannot meet specifications without overheating.
Their answer is to throttle SSDs to low power and temperature, which compromises the throughput performance, low latency consistency, and Quality of Service.
아키텍처
FADU Reinvented the FLASH Controller from the Ground Up
In 2015, we invented a new design to overcome the limitations and establish an architectural roadmap that scales as generations pushed performance and power.
- Simplified the FTL
- Replaced the complex CPU with a RISC-V core
- Introduces a Flash Acceleration Layer (FAL) to improve QoS
- Eliminated common controls between the host, CPU and DRAM
Benefits
Maximize Performance by Minimizing Throttle
FADU’s controller keeps cool, leaving more thermal headroom for NAND memory and running virtually full-throttle so NAND stays cool and performance peaks.
Save OpEx by Reducing Energy Consumption
Cooling and powering storage arrays has no ROI. FADU’s architecture saves OpEx on both cooling and from lower controller power consumption.
Achieve Peak, Sustained QoS and Consistent Low Latency
We’ve added new accelerators and schedulers enabling FADU to deliver extraordinary Quality of Service (QoS) to help meet the most stringent Service Level Agreements.
