In-system monitoring can be used to lower the risk of field failures and maintenance costs. For example, if an SSD is designed to last ten years in an embedded system and usage increases significantly, it may not last ten years as intended.

Monitoring the SSD life span in a live system is tricky since usage and workloads are different in each design. Use our software framework to collect SSD information to perform SSD life span analysis.

How it works

In Windows, vtView runs as a service. It works with the Windows Management Interface (WMI) framework. The user software retrieves data from vtView using the function of the WMI framework.

In Linux, the user software retrieves data from vtView using TCP/IP protocol. The message format is JSON.

vtView collects SMART data from Virtium’s SSD over a snapshot in time. It then analyzes the usage and determines the remaining life span of the SSD. The results are available for application software to consume.

Example Application

We provide sample applications in Windows and Linux for you to get started.

Below is a screenshot of one example. The system monitors the SSD usage weekly. In the third week of June, the workload changed drastically. The new workload causes the SSD life span to reduce to under one year, while the life span of the previous week is three years.
