D-JET 4000 system advantages
International leading performance
        The D-JET 4000 dual controller system delivers sustained bandwidth up to 4GB/s with random IOPS performance (ie disk IOPS) of up to 80,000 and burst IOPS (cache IOPS) performance of up to 1,000,000. Single system can meet the data storage performance requirements of enterprise integrated business systems;
        D-JET 4000 single system can be configured with up to 192GB of cache, large cache can provide higher performance;
        The D-JET 4000 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 4000 exceeds 99.999%, which means that the annual downtime (including planned shutdown) is less than 3 minutes. It provides high reliability measures from multiple levels, ensuring the continuous business of the D-JET 4000 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 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 redundancyThe 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 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 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 diskThe 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.;
        D-JET 4000 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;
        The D-JET 4000 single system supports tiered storage of SAS or SATA hybrid type disks, while performing system configuration, volume configuration and expansion, adding disk cabinet expansion, and routine maintenance without interrupting data access.。

High scalability
        The D-JET 4000 system has good scalability, and the D-JET 4000 controller can be used to achieve an approximately linear expansion of system performance. The D-JET 4000 single system expands the disk cabinet and disk by scaling up, enabling massive data storage up to 1984TB;
        The D-JET 4000 storage controller can configure the number of host ports and disk ports according to user requirements. Single system supports configuration of 8 8Gb/16Gb/32Gb host ports, 8 1GigE iSCSI host ports or 4 10GigE iSCSI host ports (optional) With) 6 6Gb SAS disk ports.
