SureHA is a cluster management software launched by Lenovo. It can help users build highly reliable dual-machine systems to protect their data and services. SureHA supports master-slave and peer modes. In master-slave mode, one server is designated as the master server for performing critical operations, and the other server is a hot backup server. In peer mode, all servers are designated as the master server for performing their own critical operations. The two servers are backed up to each other.
The SureHA manual explains how Lenovo's software creates a high‑availability two‑node cluster, protecting services and data by automatically detecting failures and switching to a backup server. It covers installation, configuration, and operation of both primary and backup servers.
Key topics include the software architecture, hardware requirements, network setup, service monitoring, failover procedures, and customization through scripts and agents. The guide also lists supported applications and provides troubleshooting steps for local and automatic recovery. This manual is written in Chinese.
