Huawei promises up to 90:1 compression technology by using a proprietary dynamic algorithmic technique and a lot of SSDs

• Huawei claims backup compression ratios reaching an extraordinary 90:1 level
• Patented algorithms sit at the centre of Huawei's reduction strategy
• Four separate reduction stages shrink data before long-term storage

Huawei has unveiled a hardware compression card claiming a data reduction ratio reaching as high as 90:1 under suitable workloads.

The figure applies specifically to backup data carrying high redundancy, such as daily full virtual machine backups accumulated over time.

Huawei says this result sits 20% higher than the leading alternative currently available across the enterprise storage market.

A patented algorithm built around a nonlinear transformation

The card forms part of Huawei's all-flash OceanProtect Backup Storage systems, including two newly announced models, the X8100 and X9100.

Compression relies on a proprietary algorithm family Huawei calls HZU, described by the company as using a fast nonlinear transformation paired with lightweight context prediction methods.

Huawei says this approach outperforms the long-established Lempel-Ziv compression...
