Description

aSAN collects and analyzes the IO data of SSD hard disks in the cluster, calculates the remaining lifetime of SSD hard disks, and displays the expected remaining available time of SSD in combination with the upper business pressure. According to the prediction results, it is divided into three-lifetime levels: Healthy, Medium Risk, and High Risk. Notify users to replace the SSD hard disks in the cluster in time.

Precautions

None.

Prerequisites

None.

Steps

1. Go to the Storage > Summary page, and you can view the health status of SSD lifetime in the Storage Forecast module.
2. Click SSD Lifetime to view the prediction results and alerts of the SSD lifespan.

• Assess the risk of SSD drives based on the remaining lifetime and estimated remaining usable time. It is recommended to replace risky and high-risk SSDs as soon as possible.

• High risk: Remaining life <=10%.

• Medium risk: Remaining life <=15%.

• Health: Remaining life>15%.
