SOFTWARE--HARDWARE CODESIGN
The ASIC controller of DERA NVMe SSD 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, D5000/D5007
series deliver reliable and high performance NVMe storage features.
数据可靠性
DERA NVMe SSD 的控制器芯片集成了高强度 ECC 硬件编解码单元,检测并纠正 NAND 介质访问的数据错误。
在此基础上,对完整数据通道的端到端保护、NAND 自适应冗余保护机制、意外掉电检测及处理为数据完整性
提供更多保障。D5000/D5007在运行过程中动态监测设备温度并实时处理,避免因散热条件不足导致设备损坏
丢失数据,降低了运维复杂度。
Data Integrity
The intense hardware ECC units built in D5000/D5007 series throttle errors occurred during accesses
to NAND device. D5000/D5007 series also implement end-to-end protection on the whole data paths
against silent errors, adaptive redundancy protection among independent NANDunits, and protection
against unexpected power-losses, whichare forged into an integrated protection for user data. In add-
ition, D5000/D5007 series constantly sense thetemperatures on board once powered on and react in
realtime accordingly to keep the devices from overheating disasters, decreasing the daily operation
complexities.
平稳的性能
DERA NVMe SSD 的管理算法充分预计了高压力下的极端情况和工作负载的多变性,对前端I/O请求和后台行为进
行了精细调度和控制,确保在任何情况下性能表现平稳。DERA NVMe SSD 的随机读写性能可以在相当高的负载
压力下,保持 90%以上的一致性。

Stable Performance
The FTL algorithm of D5000/D5007 series sufficiently anticipate the extreme conditions of highly-intense
workloads and workload variations with sophisticated scheduling andcontrols over front-end I/O demands
and FTL back-end activities, ensuring a stable performance in all cases. D5000/D5007 series deliver a perf-
ormance consistency above 90% in significantly heavy random I/O workloads.
