FAQ-What is the DHA function

Publication Date:  2015-07-24 Views:  681 Downloads:  0

Issue Description

What is the DHA function?


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.

The proper use of the DHA function can efficiently eliminate the hard disk faults, reduce maintenance costs, and improve the reliability of hard disks and the storage system.

The DHA function of the S5000/S2600 storage system is enabled by default. You can customize the DHA strategy on the ISM or CLI. For details, see "Configuring Disk Information Collection" in Configuration Guide.
