Integrated VMs

In most common application scenarios, storage systems require one or more servers to provide services. The purchase of this equipment is costly, providing a significant challenge to customers with budgetary constrictions. Moreover, different models of servers present compatibility issues during system deployment. These servers must be managed and maintained independently, incurring extra manpower and resource costs.

The OceanStor 2810 V5 storage system uses SmartContainer feature to provide VM functions for the traditional storage architecture. Operating systems and applications can be deployed on VMs and basic services such as video surveillance and document warehouse can be provided directly, without the need of independent server management.

Application Isolation

For economy and ease-of-use, an increasing number of enterprise IT applications are being integrated onto one hardware platform, even through such applications may affect each other. The OceanStor 2810 V5 storage system uses SmartContainer feature to address this problem. Operating systems and applications on one device are deployed on different VMs to isolate them, improving application stability and security.

Resource Control

The OceanStor 2810 V5 storage system can flexibly allocate resources to applications. Hardware resources are allocated to applications on VMs on demand to maximize application performance and make full use of hardware resources.

High Performance

The OceanStor 2810 V5 storage system employs an advanced hardware acceleration technology and is equipped with 64-bit multi-core processors, a high-speed and large-capacity cache, and high-speed interface modules. Compared with traditional storage systems, the OceanStor 2810 V5 storage system provides better storage performance and can tailor storage performance based on applications’ storage requirements.

Robust Reliability

The OceanStor 2810 V5 storage system provides power failure protection and uses advanced technologies to minimize risks of disk failures and data loss, ensuring robust system reliability.

• RAID 2.0+ underlying virtualization

  This innovative technology is employed to automatically balance loads across disks. If a disk encounters a fault, all the other disks in the same disk domain help reconstruct the faulty disk’s service data, achieving a 20-fold faster reconstruction speed than traditional RAID and significantly reducing the possibility of multi-disk failure.

• Power failure protection

  Two built-in backup battery units (BBUs) supply power to controller enclosures in the event of unexpected power failures. BBUs enable cache data to be migrated to coffer disks to avoid data loss.

• Bad sector repair

  In a storage system, the frequently occurred faults are bad sectors of disks. The OceanStor 2810 V5 storage system employs the bad sector repair technology to proactively detect and repair bad sectors, reducing the disk failure rate by 50% and prolonging the service life of disks.

• Disk pre-copy

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

• Data coffer disk

  Data 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

The OceanStor 2810 V5 storage system employs the TurboModule technology, online capacity expansion, and disk roaming to ensure uninterrupted services during routine maintenance. The functions of the TurboModule technology, online capacity expansion, and disk roaming are as follows:

• The TurboModule technology allows the hot swap of power supplies, interface modules, BBUs, and disk modules. All these modules can be operated online.
• Online capacity expansion allows you to add disks to disk domains online with ease.
• Disk roaming enables the storage system to automatically identify relocated disks and resume their services.
• If one controller is faulty, the other one can automatically take over the VMs.
• If multiple disks in a storage pool are faulty, hosts can still read and write data.

High System Security

• Management channel security

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

• Operating system security

  The 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.

• Protection against protocol and port attacks

  Only ports that are mandatory for external communication and maintenance are enabled on the storage system. All ports in use are listed in the Communication Matrix, and no unopened port exists.

• Management and maintenance security

  Users can be disabled or enabled and all management operations are logged to ensure secure and controllable management and maintenance operations.

• Service and management port isolation

  Access control lists (ACLs) are used to isolate service ports from internal heartbeat ports and management ports from maintenance ports to protect the storage system against intrusions.

  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.

Virtualization, Intelligence, and Efficiency

The OceanStor 2810 V5 storage system employs the most advanced storage design principle in virtualization, intelligence, and efficiency. Compared with traditional storage systems, the OceanStor 2810 V5 storage system delivers higher storage space utilization, faster data reconstruction speeds, smarter performance allocation technology, and finer service quality control. 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. This technology enables automatic load balancing, higher storage performance, better storage space utilization, faster disk reconstruction, and delicate storage space management, serving as a basis for a number of other advanced storage technologies.

Cost-Effectiveness and Ease-of-Use

The OceanStor 2810 V5 storage system employs intelligent fan speed control technology to achieve greater economy during operation. It also provides a series of management and maintenance tools to simplify operation and maintenance.

• Cost-effectiveness

  Intelligent fan speed control

  Dynamically adjusts the fan speed based on storage system temperature, lowering the noise and power consumption while saving device operation costs.

• Ease-of-use
  • DeviceManager

    The DeviceManager is a storage system management tool based on a graphical user interface (GUI) and enables you to efficiently manage storage systems by wizard-based operations.

  • Multiple alarm notification modes are supported so that critical information can be sent in a timely manner.
  • Cloud-based operation and maintenance (eService, also called as the Call Home service)

    Huawei provides the eService service to remotely connect OceanStor 2810 V5 storage system to the eService cloud platform, enabling centralized, remote, and intelligent operation and maintenance of storage devices. The Big Data analytics technology is used to prevent faults and locate faults quickly. In addition, it provides the optimal configuration, performance optimization suggestions, and troubleshooting solutions based on user service characteristics.
