Product Details

Huawei OceanStor S5500T storage system uses the block virtualization technology to manage hard disks, which helps automatically and properly allocate storage resources and provide available storage space for application servers.

Block virtualization is a new redundant array of independent disks (RAID) technology that divides hard disks into block-level chunks and organizes the chunks into multiple RAID groups. When a hard disk fails, all the other hard disks on the storage system participate in the reconstruction. This smashes the performance bottleneck in the reconstruction of traditional RAID groups and greatly improves the data reconstruction speed.

Storage pools are containers of storage resources. The storage resources used by application servers are all from storage pools. The storage resources of storage pools originate from disk domains.


Increased response speed

The storage system supports load balancing across the entire system. Data is distributed to the source disks of storage pools to fully use the I/O capabilities of the storage system.


As the storage system manages disks and provides storage space for application servers in the form of disk domains, user only needs to add disks to the disk domains and expand corresponding storage pools when storage capacity is found insufficient.

Enhanced self-healing capability

The storage system supports concurrent reconstruction across the entire system. Source disks of storage pools participate in reconstruction simultaneously to eliminate the performance bottleneck of traditional RAID groups and notably improve data reconstruction speed.

Balance between performance and cost

The storage system can automatically detect I/O hotspots and migrate data among storage tiers to achieve the storage performance by using dynamic storage tiering (DST).
