Device module level redundancy: All hardware components, including controllers, disk expansion enclosures, power supplies, fans, network connectivity modules, etc., are redundantly designed；
Data link redundancy：The D-JET 4000 system provides multiple data connection channels inside and outside. It can not only improve the data transmission bandwidth through multi-path I/O, but also can do link redundancy. In the case where one of the data channels is damaged, data transmission can still be guaranteed. Safety;
Device level redundancy：The connection system between the D-JET 4000 controller and the disk cabinet adopts the cross-wiring method to realize device-level redundancy, and the data transmission can be ensured even if one link-related device is damaged.；
Dual active controller structure（Active-Active）：Achieve high-availability (HA) data access, significantly improving data storage performance compared to traditional Active-Standby mode, reducing the risk of excessive single-controller load and downtime, and enabling failover To ensure the normal operation of the business；
Data consistency：The D-JET 4000 storage operating system provides 256-bit Checksum for each data block, which fully guarantees data consistency and prevents system crashes caused by data inconsistency.。
RAID protection and hot spare disk：The D-JET 4000 storage operating system supports RAID 0, 1, 5, 6, 10, 50, 60 and other methods. It not only provides complete RAID disk protection, prevents RAID write vulnerabilities, Silent Data Corruption, and improves RAID performance. During the system initialization process, a part of the physical disk is divided into global hot spare storage blocks. When the RAID group detects the faulty disk, it automatically transfers the data of the corresponding storage block on the failed disk to the hot spare storage block to enhance system security. reliability。
High availability
The D-JET 4000 system deploys a write cache image between controllers. During the process of writing write cache data to one of the controllers, the data is automatically mirrored to the write cache of another controller. It ensures the consistency of the dual controller data during the data writing process, and prevents data loss and business interruption caused by single controller damage.；
