Troubleshooting Case #007: Understanding the SSD Uptime Alert in Sangfor HCI
  

rizzuan Lv2Posted 2026-Aug-07 09:26

During routine health monitoring of our Sangfor HCI environment, I noticed several Critical Alerts related to SSD uptime.
At first glance, seeing a "Critical" alert naturally raises concern because storage devices are one of the most important components in an HCI cluster.
However, after reviewing the alert carefully, I realized that understanding the meaning behind the alert is just as important as responding to it.

Issue Description
The HCI dashboard reported the following alert:
"The current uptime of the SSD is 5.6 years, which is greater than or equal to the threshold (5.0 years)."
Since multiple SSDs generated the same alert, the first question was:
Does this indicate an imminent SSD failure, or is it a preventive maintenance reminder?

Environment
Product : Sangfor Hyper-Converged Infrastructure (HCI)
Component : SSD Storage
Alert Severity : Critical
Alert Type : SSD Uptime Threshold

Investigation
► Step 1 – Review the Alert Details
The alert specifically references the SSD operating time exceeding the predefined threshold of five years.
It does not indicate media errors, read/write failures, or hardware faults.

► Step 2 – Verify Cluster Health
Before considering any hardware replacement, I verified the overall HCI health.
Checks performed:
☑ Cluster Health Status
☑ Storage Health Status
☑ Node Status
☑ Virtual Machine Status
No abnormal behaviour or service interruption was observed.

► Step 3 – Review Storage Performance
I checked for any signs of storage degradation, including:
☑ Storage latency
☑ Read and write performance
☑ Disk-related alarms
At the time of inspection, storage performance remained stable.

► Step 4 – Review Vendor Recommendation
The alert recommendation states:
"Please focus more on inspections to detect alerts and monitor device status in a timely manner."
This suggests that the alert is intended as a proactive maintenance reminder rather than confirmation of an immediate hardware failure.

Root Cause Analysis
The alert is triggered because the SSD has been operating longer than the configured lifecycle threshold of five years.
The alert is based on operating age rather than evidence of an actual hardware failure.
Further verification of SSD health should always be performed before deciding to replace any hardware.

Recommended Actions
☑ Continue monitoring SSD health regularly.
☑ Review storage-related alerts for any new abnormalities.
☑ Check disk health information (such as SMART data, if available).
☑ Monitor storage latency and virtual machine performance.
☑ Include SSD replacement planning as part of preventive maintenance.

Verification
After completing the investigation:
☑ Cluster Health remained normal.
☑ No storage performance degradation was observed.
☑ Virtual machines continued operating normally.
☑ No immediate hardware replacement was required based solely on this alert.

Lessons Learned
Not every Critical Alert indicates an immediate production issue.
Some alerts are designed to provide early warning so administrators have sufficient time to evaluate the infrastructure and plan maintenance activities before an actual failure occurs.
Understanding the purpose of each alert helps prevent unnecessary hardware replacement while supporting a more proactive maintenance strategy.

Quick Checklist
☐ Review alert details.
☐ Verify overall cluster health.
☐ Check storage performance.
☐ Review disk health information.
☐ Monitor for additional hardware alerts.
☐ Plan preventive maintenance if required.

Discussion
Has anyone else encountered this SSD Uptime Alert in Sangfor HCI?
Did you replace the SSD immediately, or did you continue monitoring its health and performance before making a replacement decision?
I would be interested to hear how other engineers handle this type of alert in their production environments.

Hi, Regarding these critical SSD uptime notifications: if other indicators remain within normal limits, the notification might simply serve as a reminder to increase monitoring rather than an instruction to replace the SSD immediately.

Of course, if the SSD also shows signs of declining health, an increase in errors, abnormal latency, or other hardware-related warnings, then planning for a replacement is a wise move.

Conclusion: Critical notifications should always be followed up with an inspection; however, they do not automatically necessitate hardware replacement without first understanding the root cause and thoroughly assessing the drive's health.
