Overview

The data compaction algorithm of the Kunpeng BoostKit for SDS is deployed on the open-source distributed storage cluster Ceph to eliminate data waste caused by zero padding. In addition, combined with functions including data encapsulation, space allocation based on block counting, granularity-based traffic diversion, batch submission, and batch callback, the data compaction algorithm improves the data reduction ratio and overall system IOPS, which reduces costs and improves performance.

This document describes how to enable the data compaction algorithm on Ceph. The data compaction algorithm consists of an open-source patch and a closed-source RPM package. After integrating the data compaction software into Ceph source code, compile and deploy Ceph. The data compaction function takes effect in the Ceph cluster.
