FusionStorage features elastic scalability, superb performance, robust reliability, solid security, enhanced data protection, outstanding intelligence, efficiency, and cost-effectiveness, high usability, and wide compatibility. It has multiple data protection features, including HyperMetro, HyperReplication, HyperSnap, and HyperClone, as well as a variety of features to improve space utilization and performance, such as SmartDedupe, SmartCompression, SmartThin (thin provisioning), SmartQoS (Quality of Service), and SmartCache (caching). It is compatible with various virtualization platforms and applications.

Elastic Scalability

FusionStorage employs a distributed hash table (DHT) architecture to distribute metadata onto storage nodes according to predefined rules, preventing metadata bottlenecks caused by cross-node access. This core architecture ensures large-scale linear expansion.

FusionStorage leverages an innovative data fragmentation technology and a DHT-based data routing algorithm to evenly distribute volume data to large resource pools. The load sharing across hardware resources enables each volume to deliver better IOPS and MBPS performance. In addition, multiple volumes share the disks in a resource pool. Resources can be flexibly allocated to each application as the load changes, preventing load imbalance incurred by traditional Redundant Array of Independent Disks (RAID).

Superb Performance

FusionStorage leverages dynamic intelligent partitioning, static disk selection algorithms, Huawei-developed EC algorithms, small I/O aggregation, and large I/O passthrough to achieve balanced service distribution, robust reliability, and superb performance. While using HDDs as the main storage, FusionStorage adopts the distributed SSD cache acceleration solution to build SSDs on each storage node into a shared distributed cache resource pool for all services, accelerating the performance of HDDs.

Robust Reliability

FusionStorage implements distributed cluster management where systems are deployed in full redundancy mode, eliminating single points of failure (SPOFs). In addition, it supports multi-copy and erasure coding (EC) data redundancy protection mechanisms, data integrity check functions, including data integrity field (DIF) and background data consistency check, as well as flexible data reliability policies, such as system subhealth detection and handling.

  • Cluster management

    Cluster management eliminates system SPOFs. A faulty node or disk is automatically isolated, preventing adverse impact on system services.

  • Multiple copies

    The multi-copy mechanism enables a piece of data to have two or three copies. The copies are stored in different servers, cabinets, or even equipment rooms. This ensures data integrity and availability even if a server, cabinet, or equipment room fails.

  • EC

    EC implements RAID between nodes. Data integrity is not compromised by node or disk failures as long as the number of failed nodes or disks does not exceed the maximum allowed by specified EC schemes. Compared with the multi-copy mechanism, EC delivers the same or even higher reliability and remarkably improves space utilization.

  • DIF

    When receiving user data, the system calculates a cyclic redundancy check (CRC) for the data and inserts the CRC into the DIF. Then, the system sets check points in key data flow channels. If a newly calculated CRC is inconsistent with that in the DIF, an error has occurred during data transmission. In this case, the system will attempt to automatically rectify the error and reports an alarm to ensure data consistency.

  • Background data consistency check

    FusionStorage supports background scan of Bad Sector Tags (BSTs) and disks. The system will automatically restore data if bad sectors are detected during data reads/writes or background scanning.

  • System subhealth detection and handling

    FusionStorage checks the status of resources using performance indicators, such as latency. If the values of the performance indicators exceed preset ranges, the resources are subhealthy. In this case, the system will isolate the resources and recover system services.

Solid Security

FusionStorage safeguards security in the following aspects:

  • Network
    • Proper port openness

      Only ports required for implementing system functions are opened, preventing security risks caused by opening unnecessary ports.

      For details about monitoring ports of each plane, see FusionStorage Communication Matrix of the desired version.

    • Network isolation

      FusionStorage consists of a management network, service network, storage network, BMC network, replication network, and quorum network (which is required only when the HyperMetro feature is enabled). These networks are isolated by Virtual Local Area Networks (VLANs) to enhance system security.

  • Operating system

    FusionStorage supports security hardening for the Euler operating system and periodic patch release to fix vulnerabilities.

  • Data storage

    Before storage, data can be encrypted by using self-encrypting disks (SEDs) and the internal key management service.

  • Management
    • Access

      A secure authentication mechanism is adopted for interface invoking. Different accounts are used for different service operations. The passwords of these accounts can be changed or reset.

    • Transmission

      Data transmission over HTTPS encrypted channels is supported to prevent data leakage.

Enhanced Data Protection

FusionStorage protects data using the following features:

  • HyperSnap

    Captures the state of volume data at a specific point in time. Snapshots can be exported and used to restore the volume data.

  • HyperClone

    Generates multiple readable and writable clone volumes based on a volume snapshot. The clone volumes can be used independently for testing and analysis.

  • HyperReplication

    Periodically synchronizes data from a production center to a remote disaster recovery (DR) center to implement system DR.

  • HyperMetro

    Delivers active-active read/write capabilities using two FusionStorage clusters. If one data center fails, the system automatically switches to the other cluster to ensure service continuity.

Outstanding Intelligence, Efficiency, and Cost-Effectiveness

FusionStorage delivers an intelligent, efficient, and cost-effective storage system using the following features:

  • SmartThin

    Allocates physical space to volumes only when users write data to the volumes, providing virtual storage resources in excess of physical storage resources.

  • SmartDedupe and SmartCompression

    SmartDedupe detects and processes duplicate data on disks, and SmartCompression reduces the space occupied by data, remarkably improving disk utilization.

  • SmartQoS

    Sets performance priorities for applications to ensure that each application receives proper resources. SmartQoS helps ensure the performance of mission-critical services.

  • SmartCache

    Organizes SSDs of storage nodes into a shared and distributed cache resource pool for services to use, improving read and write performance while fully utilizing SSD resources.

High Usability

FusionStorage supports efficient and easy-to-use unified network topology management and maintenance.

  • Administrators can access DeviceManager through its management IP address to configure and monitor the cluster system, collect performance statistics, and view alarms.
  • Administrators can use eSight for centralized management and maintenance when there are multiple FusionStorage systems, such as in scenarios where HyperMetro and HyperReplication features are enabled.
  • Connection to the eService cloud intelligent management system helps drive IT O&M activities through big data analysis and artificial intelligence (AI) technologies, identify faults in advance, reduce O&M difficulties, and improve O&M efficiency.

Wide Compatibility

FusionStorage features wide compatibility:
  • Main storage

    A variety of storage media can function as the main storage, including SATA disks, SAS disks, SSD cards, NVMe SSDs, SAS SSDs, SATA SSDs, self-encrypting SATA disks, and self-encrypting SAS disks.

  • Cache

    SSD cards, NVMe SSDs, SAS SSDs, and SATA SSDs can function as the cache and have power failure protection capabilities, ensuring zero data loss in the event of a power failure.

  • Networking

    Multiple protocols, including IB, RoCE, and TCP, are supported to interconnect storage nodes.

  • Virtualization platforms and applications

    Through standard SCSI and iSCSI interfaces, FusionStorage supports integration with various virtualization platforms, such as Xen, KVM, VMware, as well as enhanced virtualization platforms provided by different vendors, such as Huawei FusionSphere. In addition, FusionStorage supports a wide range of database applications, such as SQL Server, Oracle RAC, DB2, and Sybase, as well as various enterprise IT applications, industry applications, and web applications.

Ever-New Storage

  • Storage service update

    The modular design of FusionStorage enables storage services to be upgraded or updated by upgrading or updating microservices.

  • System rolling update

    FusionStorage supports system rolling update. Nodes and storage pools can be rolling updated in batches. This reduces upgrade risks and impacts, and improves upgrade efficiency.

  • Hardware replacement

    After services run for a long time, system software and hardware enter the lifecycle maintenance phase. Old software and hardware need to be replaced by new software and hardware. FusionStorage supports smooth hardware replacement. That is, FusionStorage will take over old platforms to ensure service continuity before old hardware is replaced, achieving smooth evolution.
