Question SSD Monitoring

[shan2020]

Looking for a recommended monitoring tool for SSD endurance monitoring. I have a poweredge with SSD remaining_endurance as 1%, where as smartctl output of smart attribute media_wearout_inidicator displaying as 100%. so both output are not inline.

Other than smartmontool any other recommended?

I either use Samsung Magician (for my Samsung drives), or I run Crystal Disk Info for the other ones to see the health of the SSDs.

Depending on the brand of the SSD, many of the larger brands offer their own monitoring ulitities (WD, Crucial, Seagate, Sandisk, Intel, etc).

thanks for your reply.

My current situation is most servers are dell PowerEdge with some SSDs provided by Dell and others are Intel, Seagate etc..

following are the smart attributes displayed. where as omreport of dell returns "remaining rated endurance as 1%"
From the below smartctl attributes other than "Media_Wearout_Indicator" anything else I can take account to consider which shows SSD endurance has gone down?

When I've had drives start going bad, the always begin showing an increase in the Reallocated_Sector_Ct value, but yours looks good in that area. The drive you show above has high readings in the Media_Wearout and Raw_Read_Error_Rate, among other SMART warnings. It appears the drive has close to 30,000 hours on it.

At this point if you are still under warranty from Dell for it, you can contact them about getting a replacement. However, if it's out of warranty, you can replace it before it totally fails or wait it until it finally dies (just make sure you have any important data backed up).

It appears the drive has close to 30,000 hours on it.

How this 30,000 hours is calculated from the smartctl attributes output? Your explanation would be helpful.

The RAW values are what I am looking at, and I believe it shows 29,626 hours. Although you can verify it in a utility like Crystal Disk Info.

That said, I also had a SSD come in a HP prebuilt system (new PC) back in 2015 and it reported being defective with some SSD utilities. It was a new unit, and the various SSD utilities were reporting incorrect data from the SSD.

Is this a new PC? Have you tried running a hardware scan in Dell SupportAssist to see what it reports back?

 

[shan2020]

these are 3 to 4 years old server. let me compare with few servers and about the smartctl output.
We can operate through iDrac or omreport commands but not sure about others.

The main target is to analyze SSD manufactured by segate,intel etc which are not possible to analyze through dell's omreport tool.
