Proven Reliability

The OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system offers protection measures against component failures and power failure, and uses advanced technologies to minimize risks of disk failures and data loss. This ensures the proven reliability of the storage system.

  • Against component failures

    The storage system components are in 1+1 redundancy and work in active-active mode. Normally, every two components are working simultaneously and share loads. If one component fails or gets offline, the other one takes over all loads and speeds up to compensate. The whole process is transparent to applications.

  • RAID 2.0+ underlying virtualization

    The storage system employs innovative RAID 2.0+ underlying virtualization technology for automatic disk load balancing. If a disk encounters a fault, all the other disks in the same disk domain help construct the faulty disk's service data, achieving a 20-fold faster reconstruction speed than traditional RAID technology. In addition, RAID 2.0+ significantly reduces the possibility of multi-disk failure.

  • Against unexpected downtime

    The storage system is equipped with backup battery modules (BBUs) that provide power for the controller enclosure in the event of a power failure. This protects the data in the cache and dumps it to the build-in disks of the controllers to avoid data loss.

  • Bad sector repair

    The storage system is prone to bad sectors of disks. The OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system adopts the bad sector repair technology to proactively detect and repair bad sectors, reduce the disk failure rate by 50%, and prolong the service life of disks.

  • Disk pre-copy

    The disk pre-copy technology enables the storage system to routinely check the hardware status and migrate data from any failing disk to minimize the risks of data loss.

  • IP address floating

    The storage system adopts IP address floating technology. If a physical host port that implements the NAS protocol is damaged, the IP address assigned to that port automatically floats to another functional port. Based on the correct networking, services are seamlessly switched over, preventing damage to a port from affecting services.

High Availability

The OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system uses TurboModule, online capacity expansion, and disk roaming technologies to provide high availability for applications and nonstop system running during maintenance. The functions of TurboModule, online capacity expansion, and disk roaming are as follows:
  • TurboModule enables controllers, fans, power modules, interface modules, BBUs, and disks to be hot-swapped without restarting the storage system, allowing online operations.
  • Dynamic capacity expansion enables users to add disks to a disk domain in an online and easy manner.
  • Disk roaming enables a storage system to automatically identify relocated disks and resume their services.

High System Security

  • Security of management channels

    The management operations from physical ports are controlled by the access authentication mechanism of the storage system, and only authorized users are allowed to manage the storage system.

  • Security of the operating system

    The storage system's native operating system has past the compatibility test and vulnerability scanning test. Therefore, the operating system has wide compatibility and no high-risk vulnerability exists.

  • Anti-attack protection for protocols and ports

    The storage system provides only necessary ports to the external for system operations and maintenance. All the ports used are listed in the Communication Matrix. Dynamic listening ports are functioning in the proper scope, and no unopened port exists.

  • Security of management and maintenance

    The operations of users can be allowed and denied. All management operations are logged by the system.

  • Encrypted data transfer

    Virtual private network (VPN) devices are used to establish an internet small computer system interface (iSCSI) transfer channel between two storage devices and data transferred between storage devices is encrypted to ensure privacy and security. Therefore, encrypted data transfer can apply to service data transfer in using value-added features, such as LUN copy, synchronous remote replication, and asynchronous remote replication.

  • Data sanitation

    When deleting unwanted data, the system erases the specified LUN to make the deleted data unable to be restored, preventing critical data leaks.

  • Service ports are isolated from management ports

    The Access Control List (ACL) mechanism is adopted to isolate Ethernet ports from internal heartbeat network ports, management network ports, and maintenance network ports.

    NOTE:

    Internal heartbeat links are established between controllers for these controllers to detect each other's working status. You do not need to separately connect cables.

  • Data integrity protection and tamper resistance

    The write once read many (WORM) feature allows users to set critical data to read-only state, preventing unauthorized data change and deletion during a specified period of time.

Virtualization, Intelligence, and Efficiency

The OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system absorbs the concept of "Virtualization, Intelligence, and Efficiency", which fits the up-to-date storage design idea and wins a leading position for the storage system. Compared with traditional storage systems, the OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system achieves a higher storage space usage, faster data reconstruction speed, smarter performance allocation technology, and finer service quality control. To obtain the previous achievements, the following technologies contribute:
  • RAID 2.0+ underlying virtualization

    RAID 2.0+ underlying virtualization technology divides disk storage space into small-sized data blocks and uses the blocks to create RAID groups for fine-grained resource management. The technology realizes automatic load balancing, higher storage performance, better storage space utilization, faster disk reconstruction, and delicate storage space management. RAID 2.0+ serves as a basis for a number of other advanced storage technologies.

  • SmartTier (intelligent storage tiering)

    Enables a storage system to automatically analyze data access frequency per unit time and relocate data to disks of different performance levels based on the analysis result. (High-performance disks store hot data, performance disks store warm data, and large-capacity disks store cold data.) In this way, the optimal overall performance is achieved and the per IOPS cost is reduced.

  • SmartQoS (intelligent service quality control)

    Enables a storage system to categorize service data based on data characteristics (each category represents a type of application) and set a priority and performance objective for each category. In this way, resources are provided for services properly, ensuring mission-critical services' performance.

  • Thin provisioning

    Allows on-demand allocation of storage space rather than the traditional method of pre-allocating all storage space at the initial stage. It is more efficient because the amount of resources used is close to the amount of resources allocated. In this way, the initial purchase cost and total cost of ownership are reduced.

  • SmartCache (intelligent storage cache)

    Uses SSDs as cache resources to significantly promote system read performance when random, small I/Os with hot data require more read operations than write operations.

Economy and Ease-of-Use

The OceanStor 5300 V3/5500 V3/5600 V3/5800 V3/6800 V3 storage system employs intelligent CPU frequency control, delicate fan speed control, deduplication and compression to improve economy. It also provides a series of management and maintenance tools to simplify operation and maintenance tasks.

  • Economy
    • Intelligent CPU frequency control

      Automatically changes the CPU frequency based on the system loads, that is, it decreases the CPU frequency and power consumption during off-peak hours for a low operation cost and long CPU service life.

    • Delicate fan speed control

      Dynamically adjusts the fan speed based on the storage system's temperature. It lowers the noise and power consumption and cuts the operation cost.

    • Deduplication and compression

      Checks and processes duplicate data in disks based on deduplication, and minimizes space occupied by data based on compression to improve disk utilization.
