Huawei Achieves Unprecedented 90:1 Data Reduction
27 Jun
Summary
- Huawei claims backup compression ratios reaching an extraordinary 90:1 level.
- Patented algorithms sit at the center of Huawei's reduction strategy.
- Four separate reduction stages shrink data before long-term storage.
Huawei has introduced a new hardware compression card with an impressive data reduction ratio of up to 90:1 for specific backup data. This breakthrough is achieved through patented algorithms developed by Huawei, distinct from traditional methods like Lempel-Ziv, offering an estimated 30% improvement in compression. These proprietary algorithms, part of the HZU family, employ fast nonlinear transformations and context prediction.
The reduction process involves four distinct stages: preprocessing, multi-layer deduplication, HZBC compression, and byte-level compaction. This advanced pipeline, integrated into Huawei's OceanProtect Backup Storage systems, also offloads processing from the main CPU. The system utilizes QLC storage media with an adaptive SLC zone for hot data, balancing cost and performance for faster recovery.
This new generation of OceanProtect systems, including the X8100 and X9100 models, offers a 50% speed increase compared to earlier versions that achieved a 72:1 ratio. The effectiveness of the 90:1 ratio will depend on specific datasets and deployment conditions. Prospective customers are advised to test the platform with their own data.
