MPS5520G3 Storage

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.

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.

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.

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.

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.

The MPS5520G3 storage controller is based on Intel’s new generation of Xeon Scalable Processors, with built-in hardware acceleration. The internal communication of the engine adopts a high-speed 100GE RDMA channel, providing excellent I/O processing capabilities. The controller can insert 25 NVMe SSDs. Each dual-port NVMe SSD directly exchanges data with two controllers. Additionally, the MPS5520G3 backend can flexibly expand NVMe hard disk enclosures and SAS hard disk enclosures, simultaneously meeting the extreme performance and capacity expansion requirements in all scenarios.

The MPS5520G3 supports the construction of an end-to-end NVMe storage architecture with extreme performance. The front-end network supports the industry-leading NVMe over Fabric technology. The hard disk channel design adopts a matrix-type full-switching architecture, effectively reducing the I/O processing latency, fully releasing the performance of the flash memory, and providing extreme IOPS and ultra-low latency. Meanwhile, the MPS5520G3 supports the iNOF technology, realizing rapid fault switching and storage plug-and-play in the NVMe over Fabric scenario.

The MPS5520G3 adopts the Maipu CloudSAN horizontal SAN expansion architecture, supporting the online horizontal expansion of the 10/25/100GE Ethernet and 16/32G FC network dual protocols. It can be expanded to a maximum of 32 storage controllers, with a 16TB first-level cache and a maximum disk-carrying capacity of 32,000 blocks, constructing a large-scale parallel storage system to meet the growing data processing needs. At the same time, it can tolerate business continuity and data non-loss when at least half of the controllers fail, enhancing the reliability of the storage system.

The MPSP storage operating system can intelligently recognize the back-end storage medium. For flash memory hard disks, it automatically executes flash memory optimization algorithms, reducing the frequency of hard disk operations, shortening the I/O path, and providing extreme performance.

Based on the automatic thin provisioning technology of ICMT, the system automatically recognizes the front-end business I/O, coordinates and dynamically allocates storage resources, which can significantly reduce the difficulty of capacity planning for system administrators.

Based on the MPSP storage software platform, global data block-level, online and post-line adaptive lossless deduplication is realized, reducing the amount of data and improving the utilization rate of storage space. The system automatically switches between online deduplication and post-line deduplication according to the business load situation, reducing the impact of deduplication processing on business performance. A second comparison is made before deleting duplicate data to avoid data loss. It supports flexibly opening and closing the deduplication function online in units of data volumes, and also supports enabling it simultaneously with the online compression function to improve the data reduction ratio.

In the same set of hardware equipment, both SAN and NAS data storage services are provided simultaneously, without the need to configure additional NAS gateway devices, reducing equipment investment, shortening the data access path, and effectively reducing the deployment and operation and maintenance complexity. NAS supports functions such as file system snapshots, replication, and dual-active, and can construct a high-reliability SAN/NAS integrated dual-active scheme.

The built-in virtualization data management engine can incorporate storage array devices of different brands and different architectures such as IP SAN and FC SAN into the unified storage resource pool of Maipu Technology for unified management, thereby effectively reducing the management difficulty and maintenance cost and improving the utilization rate of resources. In addition, the heterogeneous virtualization function can be combined with software such as replication, snapshots, and dual-active to realize local or cross-site data protection, supporting the storage products of mainstream virtualization storage manufacturers and effectively protecting the existing investments of users.

The NDM technology of Maipu Technology can realize online data migration within a single device and across devices. The front end is unaware during the migration process and the business is not interrupted. All series of hybrid array and all-flash array products of Maipu Technology support the NDM technology. The hybrid array can realize non-Interrupting data migration between the hybrid array and the all-flash array through the NDM technology. In addition, for third-party storage arrays, Maipu Technology can also realize data migration to third-party storage arrays through the NDM technology combined with the heterogeneous virtualization function, realizing resource integration.
