Huawei optimizes storage energy efficiency in data centers

On the occasion of Huawei Innovative Data Infrastructure Forum, Dr. Assaf Natanzon, Chief Architect of Data Storage at Huawei, presented the Group’s “3+1” green strategy for data storage. This strategy helps reduce power consumption per terabyte of data through four elements:

  • High density design;

  • Convergence of systems;

  • Data reduction;

  • Carbon footprint management throughout the life cycle.

According to Huawei’s Global Industry Vision (GIV) report, by 2030, 1 YB of data will be generated worldwide every year, 23 times more than in 2020. Storing massive volumes of data consumes huge amounts energy, making it essential for industry to take environmental issues into account.

Through its “3+1” strategy, Huawei wants to help reduce the carbon footprint of data centers:

High density design: Huawei uses specific components and systems to increase hardware density and improve the efficiency of heat dissipation solutions. Solid state drives are recommended as a more power efficient alternative to hard disk drives (HDDs), using 70% less power and 50% less space for the same capacity. Huawei’s use of Half Palm NVMe SSD enables its storage systems to support 36 SSDs in a 2U drive enclosure, providing significantly higher hardware density than similar products and 25% higher heat dissipation efficiency than a 2U enclosure traditional disc.

Systems convergence : Huawei ensures better resource utilization by supporting multiple protocols and eliminating silos. A single storage system supports block, file, object, and Hadoop Distributed File System (HDFS) protocols to meet differentiated needs and multiple storage types. In addition, it is possible to have multiple storage systems in data centers, thus facilitating the use of resources.

Data reduction: Huawei’s data storage uses deduplication and compression algorithms as well as a high-ratio elastic erase (EC) coding algorithm to improve space utilization and reduce data duplication. Currently, the deduplication and compression algorithms allow Huawei storage systems to achieve a data reduction ratio of 72:1, which is 20% more than the industry benchmark. In addition, Huawei’s proprietary elastic 22+2 EC algorithm achieves a maximum resource utilization rate of 91%, which is 1.75 times higher than the traditional 3-copy mechanism.

At the same time, Huawei uses renewable materials when developing its products and also reduces the weight of the packaging. Huawei also mitigates the environmental impact of its products through a global recycling strategy.
