Safe and Reliable

²  Fully Redundant Architecture: The MPS5520G3 adopts a modular and fully redundant architecture design. In the event of a failure of any component, it can achieve rapid fault isolation and online replacement of components, ensuring business continuity.

²  Dual-Controller Active-Active Architecture Design: The controllers adopt an Active-Active redundant dual-controller architecture. The data cache, I/O paths, and hard disk resources are accessed in a shared manner, realizing load balancing of storage services and enhancing the access performance of the storage system.

²  Controller Self-Healing Technology: When various controllers of the storage engine experience abnormalities simultaneously (such as crashes or software and hardware failures), the system can quickly and automatically repair itself,  resume normal operation status, and ensure that the cached data is not lost, significantly reducing the business interruption time.

²  Cache Power-Off Protection: The cache drop technology is adopted. When the storage experiences an unexpected power outage, the cached data is flushed down to the flash memory for permanent preservation by the built-in battery of the storage, ensuring that the data in the cache is not lost.

²  Cache Freezing Technology: When problems such as momentary disconnections or failures occur on the data disks, causing data to be unable to be written, the data in the cache can be frozen. After the data disk failures are repaired, the frozen cached data is flushed down to the data disks, ensuring that the data is not lost.

²  CRAID Technology: The unique IDDC + CRAID technology enables rapid reconstruction at the minute level for partial hard disk damages. A single RAID group can tolerate the failure of any three whole hard disks without data loss. Based on the global load technology, I/O is distributed across all hard disks, significantly enhancing the I/O concurrency capability and realizing rapid reconstruction. The reconstruction time for 1TB of data can be shortened to within 20 minutes. Moreover, it allows multiple disks in a RAID group to experience media failures simultaneously without data loss. Meanwhile, combined with the slow power-on technology of the hard disks in the storage system, it avoids the risks such as current overload and tripping caused by a large number of hard disks being powered on simultaneously, further ensuring the high reliability of the system.

²  Data Consistency Protection: It supports data consistency protection based on T10 PI. During the data reading and writing process, it ensures the integrity of the data along the entire path from the host port to the hard disk, preventing silent data errors and safeguarding the security of user data.

 

Comprehensive Data Protection

The MPS5520G3 provides rich data protection functions, including data snapshots, data replication, data mirroring, and symmetric dual-active features. Through these features, data management and protection from online to near-line and from local to remote are realized, easily providing users with multi-level and cross-regional storage solutions.

²  Data Snapshots: The continuous data snapshot function of Maipu Technology can create up to 2,048 incremental-based historical time-point copies for a single data volume, providing continuous data protection. When a "soft" data failure occurs, such as data corruption caused by software programs, virus attacks, or accidental deletion, the data can be quickly recovered by "rolling back" to the appropriate time-point mark. Cascade snapshots are supported, further protecting the safety of snapshot data.

²  Data Replication: It supports both synchronous and asynchronous replication and can be converted online according to business needs, taking into account both business performance and data protection. It supports local replication within the device and remote replication across devices. The replication link supports 10/25/100GE Ethernet and 16/32G FC, providing users with flexible configuration options. Asynchronous replication supports customizing the time interval of data transmission and can provide configuration modes such as continuous hopping, one-to-many, and many-to-one. In the event of an unexpected disaster, the business can be quickly recovered based on the data copy, ensuring the business continuity of the users. Synchronous replication is based on I/O-level synchronization, maintaining a completely synchronized real-time mirror of the primary data. When the primary data fails, the mirror data can provide storage services with PRO = 0.

²  Cloning: The cloning function can online provide a highly available and highly flexible data copy that is exactly the same as the production volume at a certain moment. After creating the clone, the clone volume can be immediately provided to the front-end business for use without waiting for the data synchronization to be completed. It is suitable for application scenarios where data analysis or testing is frequently performed on the generated data. It also supports forward and reverse synchronization. The system quickly synchronizes based on the differential data without the need to reclone the entire amount of data, realizing continuous protection and flexible use of the data.

²  Symmetric Storage Dual-Active: Without the need to introduce any third-party software or hardware, the dual-active operation of two storage arrays can be directly realized by two MPS5520G3 series storage arrays, which are mutually redundant. When one of the storage arrays fails, the other storage array can take over the business in real time, achieving zero RPO and RTO. The dual-active link between the devices supports 10/25/100GE Ethernet and 16/32G FC. The dual-active function can cooperate with the replication function to realize a multi-site, cross-regional ring 3DC disaster recovery plan, providing a high-reliability guarantee at the plan level.
