DHA concept of V3 storage systems

5

The Disk Health Analysis (DHA) function is used to collect information about in-service hard disks, establish a hard disk database, and create an analysis model for disk health status based on the current hard disk application technologies and abundant experience data in the database. Through the analysis model, the health status of hard disks can be diagnosed.
Properly using the DHA function can effectively prevent disk faults, reduce maintenance costs, and improve disk and system reliability.

Inband management concept
The management control data of the storage device is transferred on the same link as the service data. In a typical connection, the application server connects to the storage device by using the service network port. Install the Inband Agent software (part of the HostAgent software package) on the application server to manage the storage device without interrupting service data transfer.

Out-of-band management concept
The management control data of a storage device is transferred on a different link from the service data. In a typical connection, the maintenance terminal connects to the management network port or serial port of the storage device to manage the device, and the application server connects to the service network port of the storage device to transmit service data. The two links are independent of each other. The management mode described in the Product Documentation and Configuration Guide is the out-of-band mode.
