A single system can meet large-scale intensive interactive applications, and its powerful random IOPS performance can achieve frequent reading and writing and access requests for large files and databases, far exceeding the IOPS performance requirements of current large databases and OLTP systems.;
       D-JET 9000 single system can be configured with up to 4096GB of cache, large cache can provide higher performance;
        The D-JET 9000 system uses dynamic caching technology to intelligently use caching, reducing the use of caching in environments such as data streams, significantly improving IOPS performance and bandwidth, and providing excellent performance in mixed load environments.。

High security and reliability
        The reliability of the D-JET 9000 exceeds 99.999%, which means that the annual downtime (including planned downtime) is less than 3 minutes. It provides high reliability measures from multiple levels, ensuring the continuous business of the DxET 9000 system 7x24. Sex。
       Device module level redundancy: All hardware components, including controllers, disk expansion enclosures, power supplies, fans, network connectivity modules, etc., are redundantly designed;
        Data link redundancyThe D-JET 9000 system provides multiple data connection channels inside and outside, which not only can improve the data transmission bandwidth through multi-path I/O, but also can do link redundancy, and can guarantee data transmission in case one of the data channels is damaged. Safety;
        Device level redundancyThe connection system between the D-JET 9000 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 structureActive-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 consistencyThe D-JET 9000 storage operating system provides 256-bit Checksum for each data block, ensuring data consistency and preventing system crashes due to data inconsistency.。
        RAID protection and hot spare diskThe D-JET 9000 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 9000 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.;
        D-JET 9000 can replace I/O components and any redundant components without downtime to ensure business continuity; each disk holds storage configuration information; active disk monitoring prevents data loss caused by disk failure;
