One Minute to Learn about DHA

Latest reply: Oct 17, 2019 11:35:33 101 3 3 0

Hi, everyone!

Today, let's talk about DHA. Speaking of DHA, people often think of a nutritional element, a fatty acid that can improve our memory.

Sorry, you are wrong.


The DHA we are talking about today is a technology that is commonly used in storage devices to detect the health status of hard disks.


What is DHA?


The full name of DHA is Disk Health Analysis, the hard disk health check.

It is mainly used to obtain information about hard disks that are being used on the network, establish a hard disk information database, and establish a health analysis model of a hard disk by using the existing hard disk application technology and a large amount of empirical data in the database, so as to diagnose the health status of the hard disk by using the model.


That is means that we can use DHA to detect the health status of our existing hard disks, which sounds great.


What is the function of DHA?


The DHA function can be effectively prevented as the following:

  • Prevent hard disk faults from occurring. DHA can be used to predict which hard disks may be faulty in time.

  • Improves the high availability of hard disks and systems, detects fault points in advance and eliminates problems to ensure high service availability. The maintenance cost is reduced, and the service interruption caused by the fault is reduced. 

  • Improves the high availability of hard disks and systems, detects fault points in advance, and eliminates problems to ensure high service availability. The maintenance cost is reduced, and the service interruption caused by the fault is reduced. 


How to configure DHA?


We have already said many advantages of DHA, so how do we use DHA? You can run commands to enable, set, and view DHA functions. For example:


  • The change dha switch command, which is used to enable or disable DHA statistics on the local controller.

  • The show dha servicestatus command, which is used to query the status of the DHA service.

  • The show dha score command, which is used to query the health score of a hard disk.


For more command about DHA, please refer to DHA Command.


That's all for today. I hope it will be helpful to all of you! i_f21.gif
