• Component failure protection

  Storage system components are in 1+1 redundancy and work in active-active mode. Normally, the two redundant components are working simultaneously and share loads. If one component fails or is offline, the other one takes over all loads without affecting ongoing services.

• RAID 2.0+

  The RAID 2.0+ underlying virtualization technology is used to automatically balance loads across disks. If a disk encounters a fault, all the other disks in the same disk domain help reconstruct the faulty disk’s service data, achieving a 20-fold faster reconstruction speed than traditional RAID and significantly reducing the possibility of multi-disk failure. RAID 2.0+ supports dynamic RAID and flexible data layout, accelerating SSD reconstruction.

• Power failure protection

  Built-in backup battery units (BBUs) supply power to controller enclosures in the event of unexpected power failures. BBUs enable cache data to be written to built-in disks of controllers to avoid data loss.

• Global wear leveling

  The wear degrees vary among SSDs. Some SSDs are damaged ahead of the normal period and the maintenance costs will increase. OceanStor Dorado3000 V3, Dorado5000 V3, and Dorado6000 V3 storage system adopts the global wear leveling technology to wear-level all SSDs evenly, extending the SSD lifespan.

• Global anti-wear leveling

  If the wear degree of an SSD reaches the threshold, OceanStor Dorado3000 V3, Dorado5000 V3, and Dorado6000 V3 storage system uses the global anti-wear leveling technology to wear SSD one by one. This technology prevents concurrent failures of multiple SSDs, thereby significantly improving reliability of the storage system.

• Disk data pre-copy

  The disk data pre-copy technology enables the storage system to routinely check hardware status and migrate data from any failing disk to minimize the risks of data loss.
