Software-hardware codesign

The ASIC controller of Dera NVMe SSD D5437/D5457/D5850/D5450/D5430 is developed by DERA with software-hardware co-design methodology. Built-in with many purpose-specific hardware units, the controller enables enterprise-class data integrity, sophisticated NAND flash management, and performance aggregation in a power-efficient way. Orchestrated by the FTL designed at the same pace with the controller, D5437/D5457/D5850/D5450/D5430 series deliver reliable and high performance NVMe storage features.

Data Integrity

The intense hardware ECC units built in D5437/D5457/D5850/D5450/D5430 throttle errors occurred during accesses to NAND device. D5437/D5457/D5850/D5450/D5430 series also implement end-to-end protection on the whole data paths against silent errors, adaptive redundancy protection among independent NAND units, and protection against unexpected power-losses, which are forged into an integrated protection for user data. Inaddition, D5437/D5457/D5850/D5450/D5430 series constantly sense the temperatures on board once powered on and react in realtime accordingly to keep the devices from overheating disasters, decreasing the daily operation complexities.

Stable Performance

The FTL algorithm of D5437/D5457/D5850/D5450/D5430 sufficiently anticipate the extreme conditions of highly-intense workloads and workload variations with sophisticated scheduling and controls over front-end I/O demands and FTL backend activities, ensuring a stable performance in all cases. D5437/D5457/D5850/D5450/D5430 series deliver a performance consistency above 90% in significantly heavy random I/O workloads.
