What are the HostAgent software components? What are their functions?
The HostAgent software has three components: HyperManager, ConsistentAgent, and InbandAgent. The three cooperate to achieve the hosts' centralized management on storage systems. Their functions are as follows:
HyperManager helps storage systems to achieve value-added functions. By using HyperManager, the hosts can create various backup and disaster recovery policies.
ConsistentAgent invokes the data consistency interfaces of various applications, and flush the data cached in databases to hard disks, ensuring data consistency.
InbandAgent enables hosts to send in-band management commands to storage systems, allowing the communication between hosts and storage systems.
