OceanStor 18500 V5

Trusted, Ensuring 24/7 Availability for Core Services

The OceanStor 18000 V5 series adopts SmartMatrix 2.0 architecture that provides full switching, full virtualization, full redundancy, and inherent load balance. The architecture integrates with advanced data protection technologies such as end-to-end data integrity, memory error checking and correcting (ECC), and transmission channel cyclic redundancy check (CRC) to boost mission-critical services of medium- and large-sized data centers. The advanced hardware and various data protection technologies enable linear storage performance growth, 24/7 storage service, and high system security.

• Innovative SmartMatrix 2.0 architectureA full-switching hardware architecture with the mission critical storage-dedicated OceanStor OS operating system meets most stringent reliability, performance and capacity requirements.
• Full redundancyIntelligent redundancy technology is implemented for all hardware components in the storage system, ensuring service continuity in harsh scenarios.
• RAID 2.0+ technologyRAID 2.0+ technology achieves load balance across disks, and accelerates data recovery by 20 times.
• Intelligent protection dedicated to core servicesThe SmartQoS and SmartPartition features provide advanced protection for core services.
• Complete disaster recovery solutionThe Hyper series management software suite provides a complete data protection strategy and disaster recovery solution.
• Data protection in the event of a controller failure
  • Built-in backup battery units (BBUs) supply power to controller enclosures in the event of unexpected power failures. BBUs enable cache data to be written to built-in disks of controllers to avoid data loss.
  • When a piece of software is faulty, the storage system will attempt to reboot. During the reboot, data is stored in the cache. If the reboot fails, data in the cache will be written into the built-in disks of controllers to avoid data loss.
  • If hardware of a controller is faulty, the storage system will use the memory mirroring technology to enable the other normal controller to take over the services to ensure data consistency.
• Online disk diagnosisThe online disk diagnosis feature is used to handle disk faults. If a disk fault occurs, the storage system takes the disk offline. Then, the online diagnosis module reads the S.M.A.R.T information about the disk and takes analysis, testing, and recovery measures. After the disk is recovered, the online diagnosis module enables the disk to rejoin the RAID, prolonging the lifecycle of the disk.
• Data coffer diskData coffer disks consist of the first four disks of a storage system’s disk enclosure as well as each controller’s built-in disks. They store three types of data: cache data requiring power failure protection, OceanStor OS system data, and system configuration information and logs.
• Hot-swappable componentsControllers, fans, power supplies, interface modules, BBUs, and disk modules are hot swappable and can be operated online.
• Quick document incremental backup with Tivoli Storage Manager (TSM)When the storage system interworks with the TSM backup software to perform incremental file backup, the Snapdiff feature uses the snapshot mechanism to quickly obtain differential file information and identify changed files. Without the need for full scanning, only changed files are backed, greatly shortening backup time. The backup performance is not affected by the number of files, which greatly improves the backup efficiency.

High System Security

Storage network security:

• Security of management channelsManagement operations from physical ports are controlled by a storage system’s access authentication mechanism, and only authorized users are allowed to manage the storage system.
• Anti-attack protection for protocols and portsThe 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.
• Isolation between service ports and management portsThe Access Control List (ACL) mechanism is adopted to isolate Ethernet ports from internal heartbeat network ports, management network ports, and maintenance network ports.

Storage service security:

• Security of the operating systemThe storage system uses a dedicated operating system. Its security has been hardened prior to delivery. The storage system updates security patches for its operating systems and open-source software based on site requirements, thereby safeguarding users’ data.
• Encrypted data transferVirtual private network (VPN) devices are used to establish an internet small computer system interface (iSCSI) transfer channel between two storage devices. Data transferred between storage devices is encrypted to ensure privacy and security. 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 storage encryptionThe storage system supports disk encryption. The hardware circuits and internal data encrypt key of disks are used for data writing encryption and data reading decryption. To ensure the security of the data encrypt key, the storage system and the third-party key management server jointly provide a highly secure, reliable, and available key management solution.
• Data destructionWhen deleting unwanted data, the system erases the specified LUN to ensure that the deleted data cannot be restored, preventing critical data leaks.
• File antivirusWhen the storage system runs a file system and shares the file system with clients through CIFS, third-party antivirus software can be used to trigger virus scanning and delete virus-infected files, improving storage system security.

Storage management security:

• Security of management and maintenanceThe operations of users can be allowed and denied. All management operations are logged by the system.
• Data integrity protection and tamper resistanceThe 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.

In addition, trusted verification is enabled during the storage system startup to measure and verify BIOS > Grub > Euler Linux Kernel > Euler Linux > Storage application software level by level to prove integrity of loaded software at each level and to prevent software tampering. The storage system’s power-on process will be verified to ensure that the system is not tampered with.
