• Disks:SAS disks, NL-SAS disks, and SSDs.
• Host interface modules:GE, 10GE, and SmartIO.

SmartIO interface modules support various port types including 8 Gbit/s Fibre Channel, 16 Gbit/s Fibre Channel, 10 Gbit/s FCoE (VN2VF), 10 Gbit/s Ethernet, and iWARP (interconnection between Scale-out nodes).

Proven Reliability

The OceanStor 2200 V3 storage system uses advanced technologies to offer protection measures, minimizing risks of failures and data loss.

• Protection against component failuresThe storage system components are in 1+1 redundancy and work in active-active mode. Normally, every two components work simultaneously and share loads. If one component fails or goes offline, the other one takes over all loads and speeds up to compensate. The whole process is transparent to applications.
• RAID 2.0+ underlying virtualizationThe storage system employs innovative RAID 2.0+ underlying virtualization technology for automatic 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.
• Data protection in the event of a controller failure
  • Built-in backup power modules supply power to controller enclosures in the event of unexpected power failures. They 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.
• Bad sector repairIn a storage system, the frequently occurred fault is bad sectors of disks. The OceanStor 2200 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-copyThe disk pre-copy technology enables the storage system to routinely check the hardware status. Once it detects that a disk has fault risks, it will enable data migration from the disk to another normal disk to prevent data loss.
• IP failoverThe storage system adopts IP failover technology. If a physical host port that implements the NAS protocol is damaged, the IP address assigned to that port automatically fails over to another functional port. Based on the correct networking, services are seamlessly failed over, preventing damage to a port from affecting services.
• 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 controller enclosure as well as each controller’s built-in disk. They store three types of data: cache data requiring power failure protection, OceanStor OS system data, and system configuration information and logs.

High Availability

In routine maintenance:

The OceanStor 2200 V3 storage system uses Turbo Module, online capacity expansion, and disk roaming technologies to provide high availability for applications and nonstop system running during maintenance.

• Turbo Module enables controllers, fans, power modules, interface modules, and disks to be hot-swappable, 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.

In data protection:

The OceanStor 2200 V3 storage system provides the following advanced data protection technologies and protocols to protect data integrity and continuous system running even when catastrophic disasters happen:

• Snapshot generates multiple point-in-time images for the source logical unit number (LUN) or source file system data. The snapshot images can be used to recover data quickly when needed.
• LUN copy backs up data among heterogeneous storage systems for data protection.
• Remote replication backs up local data onto a remote storage system for disaster recovery.
• Clone preserves a real-time physical copy of a source LUN or file system for the high availability of local data.
• HyperMirror backs up data in real time. If the source data becomes unavailable, applications can automatically use the data copy, ensuring data security and business continuity.

In resource management:

The OceanStor 2200 V3 storage system employs the following resource application technologies and provides flexible resource management to protect customers’ storage investments:

• SmartVirtualization enables a local storage system to centrally manage storage resources of heterogeneous storage systems, simplifying storage system management and reducing maintenance costs.
• SmartMigration migrates LUNs or file systems in or between storage systems, adjusting and allocating resources along with business development.

High System Security

Storage network security:

• Security of management channelsThe 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.
• 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 undisclosed interface exists.
• Service ports are isolated from 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. Security of the operating system has been hardened before the storage system is delivered. The storage systems update security patches for their operating systems and open-source software based on site requirements, safeguarding users’ data.
• 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 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 make the deleted data unable to be restored, preventing critical data leaks.

Storage management security:

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

Virtualization, Intelligence, and Efficiency

The OceanStor 2200 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 storage system introduces the following technologies to provide higher storage space usage, faster data reconstruction, smarter performance allocation, and finer service quality control:

• RAID 2.0+ underlying virtualizationDivides 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 finer 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. As a result, SmartTier optimizes overall performance and reduces costs per IOPS.
• 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 assigned to services based on priorities, ensuring the performance of mission-critical services that have the top priority.
• SmartThin (intelligent 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.
• Quick document incremental backup with Tivoli Storage Manager (TSM), applicable to V300R006C10 and laterWhen 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.
