the traditional dual-controller architecture and leading to unprecedented system scalability and availability.

PCIe-based interconnection, end-to-end reliability
The Smart Matrix architecture uses PCIe 2.0 for controller interconnection, delivering bandwidth of up to 192 GB/s. Each controller provides front- and back-end ports as well as global cache. Multiple controllers can
simultaneously flush data to disks for higher I/O efficiency.

Scale-out expansion
The Smart Matrix architecture enables system resources to increase linearly. Controllers of an OceanStor 18000 series storage system can be expanded to 16 while the system is online, along with being deployed
in a distributed manner in the data center.

RAID 2.0+ Virtualized Intelligent Volume

Next-generation intelligent disk management technology
Space on all disks in a storage system is divided into chunks. The chunks constitute chunk groups (CKGs), which are further divided into fine-grained extents. These extents then form LUNs. This process enables data to be evenly distributed to disks, greatly improving I/O performance, eliminating hotspot disks, reducing the disk failure rate, and enhancing system reliability. Each disk reserves certain hot spare space. If a disk becomes faulty, all the other disks participate in data reconstruction, accelerating data recovery by 20 times and further boosting system reliability.
Smart series resource allocation software
The Smart series software can further improve efficiency and flexibility of the OceanStor 18000 series. SmartTier automatically optimizes performance and lowers costs. SmartMotion dynamically adjusts
data distribution to balance performance and capacity among disks. SmartThin optimizes storage space utilization. SmartQoS controls service quality and prioritizes resource demands of critical services.
SmartPartition partitions and isolates storage cache, and ensures sufficient cache resources for critical services.
