RAID 2.0+ Virtualized Intelligent Volume
Next-generation intelligent disk management technology
Space on all disks in a storage system is divided into chunks. The chunks constitute chunk groups (CKGs), which are further divided into fine-grained extents. These extents then form LUNs. This process enables data to be evenly distributed to disks, greatly improving I/O performance, eliminating hotspot disks, reducing the disk failure rate, and enhancing system reliability. Each disk reserves certain hot spare space. If a disk becomes faulty, all the other disks participate in data reconstruction, accelerating data recovery by 20 times and further boosting system reliability.
Smart series resource allocation software
The Smart series software can further improve efficiency and flexibility of the OceanStor 18000 series. SmartTier automatically optimizes performance and lowers costs. SmartMotion dynamically adjusts
data distribution to balance performance and capacity among disks. SmartThin optimizes storage space utilization. SmartQoS controls service quality and prioritizes resource demands of critical services.
SmartPartition partitions and isolates storage cache, and ensures sufficient cache resources for critical services. SmartVirtualization consolidates heterogeneous storage resources, simplifying storage
management and maximizing return on investment (ROI).
Smart Series Software Allocating Storage Resources Flexibly and Efficiently
SmartQoS — Service Quality Control
SmartQoS classifies I/Os into priority-specific queues based on application priorities. Sufficient storage resources are reserved for I/O queues with a high priority to meet their performance requirements. A performance upper limit is set for applications with a low priority to prevent them from overusing resources. The execution period of a SmartQoS policy is customizable.
SmartPartition — Cache Partitioning
SmartPartition sets cache partition objectives for critical services. By dynamically allocating and isolating cache resources based on the objectives, SmartPartition prevents unnecessary cache contention and ensures performance of critical services.
SmartTier — Intelligent Storage Tiering
SmartTier creates different storage tiers based on disk types, analyzes the access frequency of data, and migrates data among tiers based on the analysis results. This feature ensures that data is stored in proper
storage media, improving system performance and reducing the total cost of ownership (TCO).
SmartMotion — Balanced Performance and Capacity Among Disks
SmartMotion analyzes the access frequency of data and available capacity of a specific type of disks, and migrates data among those disks to balance performance and capacity among disks of the same type.
This feature eliminates disk hot spots, and improves disk utilization and system performance. In system expansion, SmartMotion reallocates performance and capacity to ensure smooth expansion.
SmartThin — Optimal Resource Allocation
SmartThin allocates storage space on demand and reclaims unusedspace of typical applications such as VMware, Veritas Storage Foundation, and Windows Server. Space is allocated and reclaimed at a granularity of 64 KB. SmartThin also supports capacity pre-allocation for thin LUNs.
SmartVirtualization — Heterogeneous Storage Virtualization
SmartVirtualization takes over third-party storage systems to consolidate storage resources on a live network, make full use of legacy storage space, simplify management, and maximize the ROI.
SmartMigration — Intelligent LUN Data Migration
SmartMigration migrates LUN data without interrupting services and dynamically adjusts the migration rate based on the workload, ensuring smooth device replacement and system upgrade.
SmartErase — Intelligent LUN Data Destruction
SmartErase allows users to erase confidential data from storage media, preventing the leak of key information.
Hyper Series Data Projection Software Safeguarding Service Continuity
HyperSnap generates snapshots for a source volume of any capacity at specified points in time without interrupting system services. Those snapshots can be used for backup, testing, data mining, and data
recovery against viruses and misoperations. HyperSnap stores only changed data to save storage space.
HyperClone generates physical copies (data mirrors) for a primary LUN. By synchronizing data from a primary LUN to its secondary LUN and then splitting the pair, a user can obtain a physical copy of the primary LUN. A primary LUN in a HyperClone task can have a maximum of 16 physical copies that are applicable to different scenarios.
HyperReplication/S (synchronous remote replication) replicates data synchronously from a primary LUN to a secondary LUN on another storage array. Data is consistent between the primary and secondary
LUNs. This feature ensures data availability at disaster recovery sites and helps achieve zero data loss.
HyperReplication/A (asynchronous remote replication) replicates data asynchronously from a primary LUN to a secondary LUN at a remote site up to thousands of kilometers away. HyperReplication/A supports a minimum RPO of 5 seconds, minimizing data loss caused by system downtime. The customizable periodic synchronization policy helpsminimize the impact on application and host performance.
HyperReplication/CG adds multiple data volumes that share the same replication policy to a consistency group, ensuring data consistency among these data volumes.
Huawei OceanStor ReplicationDirector software is designed to manage the disaster recovery of enterprise data centers. ReplicationDirector incorporates application awareness and Huawei storage value-added
features to ensure application data consistency during the disaster recovery. The software helps users efficiently and easily configure and monitor disaster recovery services, and perform disaster recovery drills
and recover data rapidly.
