Huawei OceanStor UDS massive storage system (UDS for short) employs high-density and energy-saving storage nodes based on ARM architecture, as well as P2P distributed storage engines to bring extensive scalability and bally low total cost of ownership (TCO). The UDS can combine with the various application systems to provide enterprises and service providers with end-to-end solutions, such as mass resource pool, web disk, cloud backup and active archive.

Unlimited Scalability

• EB-Level Scalability: Supports in-service terabyte-to-exabyte capacity expansion and on-demand storage resource allocation.
• Fine-grained extension: Supports linear performance increase along with capacity expansion. The minimum extension unit is SmartDisks (a SmartDisk is the smallest storage unit integrating ARM processor and disk in the UDS).
• Cross-region unified storage pool: Offers a unified storage pool for multiple data centers and cross-regional data redundancy.

Extreme Reliability

• SmartDisk: Complete faults isolation by providing independent CPU and network resources for each SmartDisk. Any SmartDisk failure will be treated as single point of failure which does not affect the others. Achieves high data durability based on tiered reliability mechanism from the smallest SmartDisk level to cross-region data center level.
• Self-healing: Offers a powerful self-healing function with parallel data recovery on multiple nodes. Self-healing procedure is transparent to the application systems.
• Data security: Takes multidimensional measures, such as multi-tenants, encryption, and data partitioning to protect privacy of user data.

Low TCO

• High-density and low energy consumption complete machine design: Incorporates high-density (75 disk slots in 4U enclosure) complete machine design to provide more than 2 PB storage capacity per cabinet. Employs delicate energy consumption control, ARM processors reduce the system power consumption by 50% and decrease the maximum power consumption per terabyte to 4.2 Watt.
• Exemption from immediate maintenance: Boasts intelligent system monitoring and analysis. Design for unattended system management which eliminates the need for immediate replacement of faulty parts.
• Platform openness and easy integration: System can be easily integrated with applications via standardized interfaces and API/SDK while keeping the capability of carrying multiple applications on one platform, protecting customer investments.
