Hello,
After upgrading a lot of iDRAC9 modules to version 6.10 in servers that are involved in a
Ceph cluster we noticed that the iDRAC9 shows the write endurance as 0% on any
non-certified disk.
OMSA still shows the correct remaining write endurance but I am assuming that they are
working feverishly to eliminate that too.
I opened a support ticket with Dell once this was brought to my attention and they
basically told me that I was lucky that it ever worked at all, which I thought was an odd
response given that the iDRAC enterprise licenses cost several hundred dollars each.
I know that the old Intel Datacenter Tool used to be able to reach through a MegaRAID
controller and read the remaining write endurance but that tool is essentially defunct
now.
What are you folks using to monitor your write endurance on your SSDs that you
couldn't buy from Dell because they had a 16 week lead time while the MFG could
deliver the drives in 3 days?
Thanks,
-Drew

Our Ceph servers are SuperMicro not Dell but this approach is
portable. We wrote a little shell script to parse the output of "nvme"
and/or "smartctl" every hour and send the data to a Graphite server.
We have a Grafana dashboard to display the all-important graphs. After
~5 years life, our most worn NVMe (used for journal/db only -- data is
on HDD) is showing 89% life remaining.

That is pretty awesome, I will look into doing it that way. All of our monitoring is
integrated to use the very very expensive DRAC enterprise license we pay for (my fault for
trusting Dell).
We are looking for a new hardware vendor but this will likely work for the mistake we
already made.
Thanks,
