        D-Fusion 3000 series products include: D-Fusion 3200, D-Fusion 3500。

Unified storage architecture
        The D-Fusion 3000 unified storage system consists of two storage controllers, which are dual-control high-availability cluster storage systems, and support NAS and IP SAN storage networks.;
        The D-Fusion 3000 storage controller provides up to 12 GigE host interfaces, which can extend the 10GigE host interface, and the Ethernet interface supports LACP Trunking. The D-Fusion 3000 unified storage system provides optimized CIFS, NFS v2/v3/v4, FTP and HTTP access modes, and supports a mix of Linux, Unix, Windows, Solaris, IBM AIX and other operating systems in a TCP/IP network. Shared access to the environment;
       The D-Fusion 3000 unified storage system supports SAS disks and SATA disks. It supports the mixing of different types of disks in a single system and supports hot swapping of disks.。

 International leading performance
       Delivering up to 4GB/s of consistently stable bandwidth, the D-Fusion 3000 dual-controller system delivers over 160,000 OPS (operating operations per second), meeting the high-bandwidth performance requirements of high-performance business environments, and The demanding OPS requirements in small file processing, and such high performance can still be maintained under the simultaneous access of thousands of client servers;
        The D-Fusion 3000 unified storage system can meet the high bandwidth requirements of large file services, and can provide frequent reading, writing and requesting of large files and databases, and can easily open and access large directories containing more than 1 million files.。

Excellent expansionperformance
       The capacity of the D-Fusion 3000 system can reach 4416TB. The expansion operation can be performed online. It only needs to access more extended disk cabinets in real time, and will not affect the existing business operations.。

High security and reliabilitySex
        D-Fusion  The reliability of the 3000 unified storage system exceeds 99.999%, that is, the annual downtime (including planned downtime) is less than 3 minutes. It provides all aspects of high reliability protection measures from hardware, system, architecture and other aspects.。
Hardware layer
       All hardware components of the D-Fusion 3000 unified storage system, including controllers, power supplies, fans, and network connections, are redundantly designed.。
        The D-Fusion 3000 unified storage system uses real-time data checksum to automatically check and repair possible damaged sectors of the disk to ensure data integrity.。
System layer
        The D-Fusion 3000 unified storage system provides RAID 0, 1, 5, 6, 10, 50, 60 and other redundancy modes to support hot spare disks and automatic RAID reconstruction. D-Fusion RAID is created very fast, usually no more than 10 seconds. RAID 6 prevents data loss or corruption in the event of simultaneous damage to both disks. D-Fusion 3000s unique dynamic striping RAID technology can also effectively preventRAID“Write vulnerability”Phenomenon occurs;
        The D-Fusion 3000s PRODIGY-SP file system maintains consistency in extreme situations such as sudden power outages or system crashes, and automatically recovers quickly when the system is restarted.。The D-Fusion 3000 does not have a separate metadata server. All metadata is managed by the controller and distributed on disk for the same reliability protection as the data. This approach is far more reliable than a separate metadata server, because the latter interrupts the business when the metadata server crashes, and it takes a long time to complete a file system consistency check task like fsck, and more serious because of metadata. Get full recovery and cause some or all of the data to be corrupted or lost。
Architecture layer
        Two D-Fusion 3000 storage controllers are connected to each other to form a high-availability cluster. The cluster working mode is Active-Active, that is, all controllers can provide data access at the same time, and the traditional active/standby working mode (Active- Compared to Standby), the performance of data storage is significantly improved. At the same time, the two or more controllers are hot standby, and any one of them fails, and the other can automatically and continuously take over the task of the fault controller and the data managed, and this is completely taken over. The process is completely transparent to the client, thus ensuring 7x24 business continuity。

 Multi-level data protection scheme
        The D-Fusion 3000 unified storage system delivers enterprise-class, advanced data protection solutions through integrated free or licensed software, including:
        Snapshot: File system-based advanced snapshot MagicShot for local disk backup and fast recovery with less impact on system performance and space;
        Cloning: File system-based instant writable data volume copy MagiClone, minimizing system performance and space impact, saving test and development time;
        Local backup: Provides NDMP protocol with Commvault, Veritas, Bakbone and other backup servers to implement LAN-free centralized incremental backup of data from D-Fusion system to tape library.;
        Remote disaster recovery: MagicMirror performs near-synchronous disaster recovery and recovery through LAN or WAN;       
        Storage Encryption: MagicVault supports high-performance encryption and global key management to protect confidential information even when data is stolen. Real-time encryption ensures data security inside the storage system, even if the disk is lost。
Thin provisioning and space management
         The D-Fusion 3000 storage controller virtualizes all storage space into a shared mass storage pool. As long as there is access, all spatial resources and data can be shared by any front-end computing node or application server. Users do not need to manage any underlying devices separately, such as disks, RAID or logical volumes (LUNs);
       The D-Fusion 3000 unified storage system supports the thin provisioning function to dynamically expand the volume size without the need for a preset volume capacity, which does not affect system operation and greatly improves space utilization.;
        D-Fusion 3000s virtualized unified storage pool technology combined with thin provisioning technology greatly improves space utilization, and effectively avoids data replication through high-performance data sharing services and snapshot and cloning services that take up less storage space. copy。
        D-Fusion 3000 provides secure access management under Linux or Windows, as well as capacity quota management at the user, directory, and file volume levels.;

Hybrid storage and tiered storage management
        Although D-Fusion 3000 virtualizes all storage space into a shared mass storage pool, you can configure different types of hard disks in the same storage system, including SAS and SATA.;
        The D-Fusion 3000 unified storage system can deploy automatic data migration and hierarchical storage management between spatial regions of two or more different disk types.。

Humanized and easy to manage
        The D-Fusion 3000 installation and deployment adopts the “Plug and Play” method. You only need to connect the Gigabit interface of the D-Fusion 3000 controller to the core IP switch through a standard network cable, configure a simple IP address and configure LACP link aggregation. Connect the SAS interface to the expansion disk enclosure and configure a simple LUN. You can start to provide unified sharing of high-performance data services;
        All the compute nodes and client servers on the front end do not need to install any client software. Non-Windows servers only need to do a simple NFS mount. Windows servers can share the global space and data resources of the D-Fusion system by mapping the network hard disk through the CIFS protocol. . Users do not need to build and configure any I/O node server and metadata server;
        The D-Fusion 3000 storage system provides a concise GUI graphical management interface and CLI command line interface for local or remote maintenance. Provides a series of enterprise-level management functions such as automatic RAID management, system status real-time monitoring and alarm, remote log, and secure network settings, greatly reducing system management and maintenance burden。

In summary, the companys D-Fusion 3000 series products are designed for high performance, scalability, and reliability, meeting the demanding workload demands of massive data storage, high-performance computing environments, and providing enterprise-class features. Sex, improve business efficiency and reduce costs。
