1. Smart Matrix architecture

The Smart Matrix architecture is a Huawei-proprietary system architecture for enterprise-level storage systems. By controller scale-out, this architecture shatters the physical restrictions of the previous architectures and improves the system scalability and availability to the highest level.


PCI-e full-switch network for an E2E reliability: The Smart Matrix architecture is based on the PCI-e 2.0 network that interconnects all OceanStor 18500/18800 controllers to exchange information. The system bandwidth reaches up to 192 GB/s. Each controller incorporates the functionality of front end, cache, and back end. Multiple controllers can send I/O requests to disks simultaneously, so the disk I/O efficiency is greatly enhanced.


Scale-out capability for 99.999% availability: The Smart Matrix architecture allows the linear expansion of system resources and online adding of a maximum of 16 controllers. The controllers can be deployed anywhere in a DC based on site requirements.



2. Fully virtualized smart volumes

In the OceanStor18500/18800, disks are divided into chunks that have a granularity exact to megabyte. Therefore, data can be evenly stored on more disks and all those disks can participate in reconstruction if any one disk fails. In this way, the reconstruction efficiency is improved and reconstruction period is shortened, and the chances of a second disk failure during reconstruction are reduced. This data storage mechanism lays a foundation for the Smart series functions and improves system reliability.



3. Smart series resource management software

The Smart series software improves the OceanStor 18500/18800 efficiency and flexibility.


SmartTier

The SmartTier automatically analyzes data access frequency in a finer data size and migrates data to a proper disk tier such as SSD, SAS, or NL-SAS. Based on application characteristics, customers can specify the data size (256 KB to 64 MB) for migration, statistical period (by hour or by day), migration mode (automatic or manual), migration period, and migration speed. The SmartTier improves the storage performance of hot data, reduces the storage cost of cold data, and increases the overall system price performance ratio.


SmartMotion

The SmartMotion automatically balances data distribution within the same disk tier to avoid system bottlenecks caused by hotspot disks, improving disk utilization and the overall disk reliability.


SmartQoS

The SmartQoS classifies I/Os into priority-specific queues according to application priorities. Sufficient storage resources are reserved for I/O queues with high priorities to meet their performance requirements, while a resource upper threshold is set for I/O queues with low priorities to avoid their overuse of resources. The execution period of the SmartQoS strategy is customizable.


SmartPartition

The SmartPartition allocates different memory capacities based on capacity requirements of applications to ensure that sufficient cache resources are reserved for mission-critical applications.


SmartThin

The SmartThin uses the 64 KB data size in allocating system storage space on demand and recycles deleted space for typical applications such as VMware, Veritas Storage Foundation, and Windows Server. It also pre-allocates space to thin LUNs, supports conversion and data replication between thin LUNs and thick LUNs.


SmartVirtualization

The SmartVirtualization simplifies the storage system management, improves the resource usage, and maximizes customers' return on invest (ROI) by integrating the resources on heterogeneous storage arrays and providing unified storage to application servers.



4. Hyper series data protection software

HyperSnap

The HyperSnap generates snapshots for online data at specified points in time without interrupting system services. Those snapshots can be used for backup, R&D, data mining, and data recovery when the original data is lost by accident. Volumes can be snapshot within several seconds regardless of their storage capacities. If you want to limit the storage space occupied by snapshots, you can use the incremental snapshot that only saves the changed data between two snapshot points in time.


HyperClone

The HyperClone generates complete physical copies (mirror data) for data on original LUNs. You can synchronize and split a primary/secondary LUN pair to obtain the physical copies. Each primary LUN can have a maximum of eight physical copies that can be separately used for different data analysis purposes.


HyperReplication /S

The HyperReplication /S mirrors data from a primary LUN to a secondary LUN on a different storage array. It is applicable to intra-city data protection and achieves zero data loss.


HyperReplication /A

The HyperReplication /A replicates data from a primary LUN to a secondary LUN in a remote location that may be thousands of kilometers away. The minimum recovery time objective (RTO) is 5 seconds, minimizing data loss during system downtime. The data replication period can also be customized to off-peak hours to minimize the adverse impact on application and host performance.


HyperReplication /CG

The HyperReplication /CG creates a consistency group comprised of multiple data volumes that have share the same replication policy. The consistency group ensures data consistency among the member data volumes.



5. 99.999% reliability

The OceanStor 18500/18800 meets customers' requirement for application availability from all aspects including architecture, module, component, data, software, and solution.


The OceanStor 18500/18800 is equipped with a maximum of 16 redundant controllers that are interconnected through a PCIe 2.0 network and connected to two redundant data switches for reliable data transmission over a long distance.


The RAID 2.0+ chunk-based volume virtualization mechanism shortens the reconstruction period of 1 TB data to 30 minutes and lowers the dual-disk failure rate.


All internal system channels such as host I/O channels, disk I/O channels, PCI-e switching channels, GE switching channels, and LAN channels have redundant paths. Those channels are separated to ensure the separation of application, control, and management planes for independent fault diagnosis and rectification.


The OceanStor 18500/18800 power supply and heat dissipation modules are also redundant. The failure of any module does not affect the stable operating of the overall system.


The Hyper series,ReplicationDirector software and UltraPath software together with the redundancy design safeguard customers' data locally and remotely. The Hyper series, ReplicationDirector software and UltraPath software play an important role in Huawei's DR solutions for strengthening the application availability.



6. Unprecedented scalability

Based on the Smart Matrix architecture, the OceanStor 18500/18800 can scale up to 3,216 disks and supports a maximum of 7.6 PB available capacity, 3 TB memory, and 256 Fibre Channel or iSCSI ports.


The OceanStor 18500/18800 is also a distributed multi-controller storage system whose controllers can be expanded from 2 to 16 without interrupting applications. It has up to eight system bays and two expansion disk bays and each system bay houses controllers. An OceanStor 18500/18800 bay can house a maximum of 192 3.5-inch disks or 408 2.5-inch disks and a disk bay can house a maximum of 192 3.5-inch disks.


The OceanStor 18500/18800 offers disks ranging from speedy enterprise-level SSDs to 4 TB NL-SAS disks. Enterprise-level SSDs carry higher workloads with less power. The storage tiering technology optimizes system performance and brings down the costs by using different types of disks. The OceanStor 18500/18800 also offers 8 Gbit/s Fibre Channel ports and 10 Gbit/s Ethernet ports used for FCoE and iSCSI connections.
