Tools to obtain P3700 current temperature?

We have got a few P3700 NVMe Gen3 PCIe SSD 800GB cards for a few of our servers, all running CentOS 7. We would like to minitor their temperature. As far as I can tell, the current smartmontools http://sourceforge.net/p/smartmontools/code/HEAD/tree/trunk/smartmontools/drivedb.h do not support NVMe devices. So, I went ahead and installed https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=21099 isdct on our servers. But other than reporting TempThreshold: 85 degree C, I didn't see any option from the Intel tool for the current drive temperature. Is there such a software tool available at all?

BTW, why the isdct states TempThreshold: 85 degree C, but https://www-ssl.intel.com/content/www/us/en/solid-state-drives/ssd-dc-p3700-spec.html its spec states (for the AIC), 0 - 55 deg C? Also, if I run smartctl -d scsi /dev/nvme0n1, it does report Current Drive Temperature, can I believe it?

Regards,

Hi Zack, the Intel® SSD Datacenter Tool can dump the temperature to a file.

This is the syntax for the command:

Isdct dump –destination -intelssd datatype=nvmelog logid=197

You may use the filename of your choice.

The value for can be found by using the show option for isdct as explained below:

First, obtain a list of installed drives:

Isdct show –intelssd

Find the Index number of the drive you want, and then issue the Dump command. Assuming the drive index in question is 0, the command would be:

Isdct dump –destination temperature.txt -intelssd 0 datatype=nvmelog logid=197

I included a screenshot of the commands.

Hi Zack,

 

I have seen a couple of comparisons, not rigorous tests, where Intel tools and smartctl have reported the same temperature. I don't think smartctl is perfectly coded to use nvme devices but in this area you may have success using smartctl. I would be smart to do your own rigorous comparisons.

Hi Joe,

I just tried getting the temperature of a P3700 card using the command "Isdct dump –destination temperature.txt -intelssd 0 datatype=nvmelog logid=197" which works. I have a few questions though

1. If I want to monitor the temperature over a time period in secs, mins and hours, how do you advise I do that as the command just displays the current temperature and dumps it into a file.

2. Reading the temperature stats on a graph

Thanks.

Regards,

Temi

Hello Topzy2000,

The Intel® SSD Data Center Tool does not include the functionality to monitor the temperature on a schedule, and it does not have the option to present the results in a graphical view. You would need to use additional software to achieve this. Here are a few aspects regarding this topic for your consideration:

- You can use the ISDCT commands in an automated script, and run it on a scheduled task (cron job).

- ISDCT can save the command output in text, JSON or NVMXML formats. You can then integrate the output into other files at your convenience.
