Intel P3700 blinking orange led

Hi All,

I've recently bought Intel's P3700 800GB SSD to our Lenovo x3650 M5 (E5-2630 v3 dual CPU) server, running Ubuntu.

Performance is not as high as it suppose to be - hdparm -tT --direct shows around 1.6GB/sec. The same drive on a friends PC shows the 2.8GB/sec it suppose to be.

While trying to debug it I've noticed that the first orange led is blinking steadily - half a second on, half a second off, etc... It is starting when Ubuntu is booting even when the drive is not mounted so there is no traffic.

I tried to shutdown the server and unplug the power sources - but no luck there.

After installing the disk i ran dd if=/dev/zero of=/dev/nvme0n1 bs=1M oflag=direct, like it suggested in the NVMe Driver Reference Guide - maybe I put the SSD is some kind of bad state?

Any other ideas? Maybe firmware? how do I find out which firmware I have? Unfortunately Intel does not support Ubuntu for the SSD Data Center Tool.

I'm do not know if the blinking causes the performance issue, but it is odd.

Thanks,

Gil.

Hi,

Maybe your SSD model is failing. http://www.dafotec.fr/ To see the chip controller you have to open it but it will void the warranty.http://www.dafotec.be/

I just want to correct something, I didn't try the drive I have on my friends PC, he has a different P3700.

rookie67, I hope you are wrong

Gilsho,

 

 

About this situation, for Ubuntu you can go ahead and download the Intel® SSD Data Center Tool for Linux* here: https://downloadcenter.intel.com/download/23931/ https://downloadcenter.intel.com/download/23931/

 

 

Also, here are the commands for you to use the Intel® SSD Data Center data http://www.intel.com/content/dam/support/us/en/documents/solid-state-drives/ssd-software/Intel_SSD_D... http://www.intel.com/content/dam/support/us/en/documents/solid-state-drives/ssd-software/Intel_SSD_D...

 

 

As well, the activity light will blink anytime there is activity, please refer to the last page from this document: http://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/ssd-dc-p3700-spec... http://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/ssd-dc-p3700-spec...

 

 

Let us know if you still require assistance.

First of all, thank you for the quick response,

1. The Linux package contains RPM installation files which doesn't suite Ubuntu. Is there an Ubuntu/Debian installation somewhere?

2. If it is true I do not understand why there is I/O activity. It is a fresh install of Ubuntu and I didn't even mount the SSD so I do not expect any traffic towards it. I'll try to investigate it from the OS side.

UPDATE

I've unpacked the .rpm files and they are running fine. I spotted that my SSD is on an "EnduranceAnalyzer" mode, and it is waiting for an hour of workload for endurance analysis. Can this cause the performance issues I have? Is there a way to disable this analyzer? I'm running a random read/write workload for over an hour and the analyzer still doesn't have sufficient data.

This is the output of isdct show -a -intelssd 0, is there something bad here?

Gilsho,

 

 

Thanks for replying back and trying the steps provided. We would like you to try the following in order to try to reset the endurance analyzer:

1. Reset SMART Attributes using the reset option.

 

 

isdct.exe set –intelssd 2 enduranceanalyzer=reset

 

 

2. Optionally, remove the SSD and install in test system.

 

 

3. Apply minimum 60-minute workload to SSD.

 

 

4. Reinstall SSD in original system if needed. Compute endurance using the show command. You can also specify the EnduranceAnalyzer property specifically using the –display (-d) option.

 

 

isdct.exe show –a –intelssd 2

 

isdct.exe show –d EnduranceAnalyzer –intelssd 2

 

 

5. Read the Endurance Analyzer value which represents the drive's life expectancy in years.

 

 

About the performance on this SSD, please make sure you are using our https://downloadcenter.intel.com/download/23929/Intel-SSD-Data-Center-Family-for-NVMe-Drivers NVMe driver.

 

 

We will be waiting for your response, have a nice day.

Hi,

I've reset the Endurance Analyzer, and rerun my workload and got the "wear prediction" - so thanks for that.

I'm using Ubuntu 14.04 with 4.2.0 Kernel, so NVME driver was compiled as a module by default:

filename: /lib/modules/4.2.0-27-generic/kernel/drivers/block/nvme.koversion: 1.0license: GPLauthor: Matthew Wilcox <</span>mailto:willy@linux.intel.com willy@linux.intel.com>srcversion: C1E91880F29AB152ED05CF5alias: pci:v*d*sv*sd*bc01sc08i02*

1. The orange light is still blinking even though there is no traffic to the SSD.

2. I'll try to be more clear about the bandwidth problem I'm talking about:

I'm running fio with simple synchronous read of a big file in the P3700. I had the chance to run it on a PC (i7-5930K) which showed the desired 2.8GB/sec bandwidth. On the other hand, on our new server (2x Xeon E5-2630v3) for the same test I get a 1.5GB, the same happened on another server I used to work on (4x E5-4650v2). I wonder what is different in the server that doesn't fully utilize the fast storage bandwidth.

Glisho,

 

 

We would like to know the model of each server you have tested so far. It seems it could be related to some configuration from each server and we would like to learn more about the specs on each one.

Gilsho,

 

 

Thanks for providing the information. We would like to know, are the other servers you have tested also Lenovo* servers?

 

If those are also Lenovo* we suggest you to contact them in order to verify the change on the speed since we do know the SSD works fine in one of them.

 

 

Please keep us updated, we will be waiting.

I have same issue P3600 here, amber LED is blinking all the time (its first LED from top - amber, others are red and yellow silent, green is ON also), no problems with data so far. My drive usage is very low. OS is VMWARE ESXi with latest driver. Server is HP Microserver Gen 8.

When in POST or in BIOS Setup LED is OFF

When Vmware driver loaded amber is blinking when Intel driver loaded -constant solid amber

Update:

https://github.com/vmware/nvme/issues/10 Intel P3600 constant blinking amber led · Issue # 10 · vmware/nvme · GitHub

can it be forwarded to Intel ESXI driver development team?

Update

I took a friend's SSD from another server and connected it to my server.

My friend's SSD orange led doesn't blink, so it seem like a SSD issue and not a server issue.

Performance on my friend's SSD is higher - 1.6GB/sec on my sync fio benchmark, while my SSD show almost 1.2GB/sec.

 

This is still not peak performance, but SSDs performance should be the same, mine is even newer so wear level and stuff are low.

The only difference I can think of between SSDs are the firmware: mine is 8DV10171 while his is 8DV10131.

I will really want to solve the orange blinking led issue, it shouldn't happen.

Please advise,

Gil.

Gilsho,

 

 

Thanks for the testing on your end.

 

We would like to review a little bit more on this since you have tested another SSD which light does not blink.

 

 

We will get back to you as soon as we confirm this behaviour, we will try both firmwares if possible as well.

Hello,

The SSD model, server, configuration and test settings are all important for performance results. If the conditions are not the same, then we would expect different results. The advertised values are noted in pages 10-11 of the http://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/ssd-dc-p3700-spec... P3700 product specifications.

Make sure that the drive is preconditioned, since that also has an impact in the performance results.

It is advised to check with Lenovo for any BIOS updates as well.

Here are some existing threads and reference documents about NVME* drive performance:

/thread/76405 Anyone measured the performance of NVMe PCIe 750 SSD using fio under Linux?

 

/thread/56790 Intel DC P3700 400GB SSD Poor performance on linux system
