英特尔P4500 U.2固态硬盘更新后驱动器速度已降至PCIe x1

嗨ShawnMunster，感谢您在英特尔社区发帖。我了解您在更新固件后遇到了PCIe接口减速问题。
我已经检查了帖子附带的日志文件，但是我想问你是否可以运行以下命令并将输出附加到这里以便我可以看看它：isdct show -a -intelssd此命令将
给我们提供有关驱动器的其他信息。注意：如果您不确定SSD索引号，请首先运行命令isdct show -intelssd以显示所有驱动器，然后在讨论中查找驱动器的索引号并最终运行命令
在此期间，我将从我这边检查是否有一个特定的命令可以修改PCIe接口正在工作的实际速度。
我知道有一个SATA驱动器，但我不确定是否还有一个PCIe驱动器的命令。另外，只是为了确认，你是否更改了固件更新后SSD连接的端口？
通常，这类问题是因为使用的PCIe插槽容量低于实际设备导致速度减慢。另外需要考虑的是NVMe *驱动程序。
请确保您已安装最新的驱动程序版本（4.0.0.1007）：https：//downloadcenter.intel.com/download/27517？v =如果您尚未更新NVMe *驱动程序，请执行此操作然后再执行此操作
运行我在开头提到的命令，以便在安装了最新驱动程序的情况下收集数据并确保SSD位于正确的PCIe插槽中。我将等待您的响应。祝您有个美好的一天.Regards，Diego V.

Hi ShawnMunster,

Thank you for posting in the Intel communities.

I understand that you are expericing a slow down on the PCIe interface after the firmware was updated. I’ve checked the log file attached to the post, but I’d like to ask you if you can run the following command and attach the output here so I can take a look at it:

isdct show  -a -intelssd

This command will give us additional information about the drive.

Note: If you are not sure about the SSD index number, run first the command isdct show -intelssd to display all drives, then look for the index number of the drive in discussion and finally run the command mentioned above.
On the meantime, I’ll check from my side if there is a specific command that can modify the actual speed the PCIe interface is working on. I know there is one for SATA drives, but I’m not sure if there is also a command for PCIe drives.

Additionally and just to confirm, have you changed the port the SSD is connected to after the firmware update? Usually, these kind of issues are because of the PCIe slot used which has a lower capacity than the actual device causing a slow down.
Another thing to consider is the NVMe* driver. Please make sure you have installed the latest driver version (4.0.0.1007) available here: https://downloadcenter.intel.com/download/27517?v=t

If you haven't updated the NVMe* driver, please do so and then run the command I mentioned at the beginning so that the data is collected with the latest driver installed and make sure the SSD is in the correct PCIe slot.

I’ll be waiting for your response.

Have a nice day.

Regards,

Diego V.

 

你好Diego V，
我有更换端口和电缆，PCIe插槽没什么区别。
仍然很慢。
这是请求的输出。
问候，
肖恩。

嗨肖恩，
感谢您的信息。
我从附件中看到你安装了最新的NVMe *驱动程序。
但是，我从上一份报告和新报告中注意到了一件有趣的事情。
如果检查共享的第一个报告，最后会看到“Current PCIe Link Speed”值为1.这意味着该驱动器正在作为PCIe 1.0设备运行。
但是，相同的值在新报告中显示为3，这意味着驱动器现在可用作PCIe 3.0设备（它显示为“PCILinkGenSpeed”）。
我不确定为什么它之前有所不同（可能是驱动程序更新了？），但从最新的报告看起来没问题。
请告诉我您如何测量驱动器性能以得出这个结论。
从您的原始帖子，我知道您正在谈论PCIe通道（x1，x4，x8，x16），但我不确定您是否指的是PCIe gen。
我混淆的原因是因为我在上面解释的报告中的信息。
此外，您拥有的驱动器接口是PCIe 3.1 x4，这意味着它是PCIe第3代设备，应连接到具有x4通道的端口。
从SSU报告中，我可以看到你有一个Z10PE-D8 WS主板，根据它的规格，它只有PCIe 3.0 x16插槽，所以驱动器应该可以正常工作。
实际上，这反映在英特尔®SSDDCT（PCIe gen 3 x4宽度）的最新报告中。
这让我再次知道你如何测量驱动速度，因为从报告中看，一切似乎都是有序的。
我会等你的回复。
祝你今天愉快。
问候，
迭戈五世

Hi Shawn,
 
 
Thank you for the information. I can see from the report attached that you have the latest NVMe* driver installed. However, there is an interesting thing that I noticed from the previous report and the new one.
 
 
If you check the first report that you shared, you will see at the end the “Current  PCIe Link Speed” value which is 1. That means that drive was working as a PCIe 1.0 device. However, the same value appears in the new report as 3 which means the drive works now as a PCIe 3.0 device (it appears as “PCILinkGenSpeed”). I’m not sure about why it was different before (maybe the driver was updated?), but from the latest report it looks to be fine.
 
 
Please let me know how you are measuring the drive performance to make this conclusion.
 


 
From your original post, I understand you are talking about the PCIe lanes (x1, x4, x8, x16), but I’m not sure if you are referring to the PCIe gen instead.  The reason of my confusion is because of the information in the reports that I explained above. Additionally, the interface of the drive you have is PCIe 3.1 x4 which means it’s a PCIe gen 3 device and should be connected to a port with x4 lanes.
 
 
From the SSU report, I can see that you have a Z10PE-D8 WS motherboard and according to its specifications, it only has PCIe 3.0 x16 slots so the drive should work fine on these. Actually, that’s reflected in the latest report from the Intel® SSD DCT (PCIe gen 3 x4 width). That makes me thing again about how you are measuring the drive speed because from the reports everything seems to be in order.
 
 
I’ll be waiting for your response.
 
 
Have a nice day.
 
 
Regards,
Diego V.

你好Diego V，
我改变PCIe插槽我得到报告PCIe 3 x4但速度与普通英特尔NVME驱动程序不一样。
适用于英特尔®固态盘的数据中心NVMe * Microsoft Windows *驱动程序
适用于NVMe *驱动程序的英特尔®SSD数据中心系列的4.0.0.1007版。
用上面的驱动程序速度只有1000 MB / s读取300 MB / s写入。
所以我从RSTe安装英特尔NVME驱动程序，现在速度更快。
问候，
肖恩

Hi  Diego V,
 
I change PCIe slot I get that report PCIe 3 x4  but speed is not  there with Normal Intel NVME driver.
 
Datacenter NVMe* Microsoft Windows* Drivers for Intel® SSDs
Version 4.0.0.1007 of the Intel® SSD Data Center Family for NVMe* drivers.
with the above driver speed was only 1000 MB/s read  300 MB/s Write.
 
so I install Intel NVME Driver from RSTe it works better speed is now.

嗨Shawn，感谢您提供的信息。如果我理解得很好，驱动器在使用RST驱动程序时会达到正常性能，而不是我在开头提到的常规NVMe *驱动程序，对吧？根据Crystal Disk Mark提供的信息
，结果是预期的，根据以下网站：https：//ark.intel.com/products/99030/Intel-SSD-DC-P4500-Series-1_0TB-2_5in-PCIe-3_1-x4-3D1-TLC
？q = SSDPE2KX010T7除非我遗漏了别的东西，现在看来驱动器工作正常，对吗？
您可以继续使用这些驱动程序，因为您可以获得驱动器的预期性能。如果还有什么我可以帮助您，请告诉我。祝您有个美好的一天.Regards，Diego V.



以下为原文

Hi Shawn,

Thank you for the information.

If I understood you well, the drive achieves its normal performance when the RST driver is used rather than the regular NVMe* driver I mentioned at the beginning, right?

According to the information from Crystal Disk Mark, the results are the expected ones according to the following site: https://ark.intel.com/products/99030/Intel-SSD-DC-P4500-Series-1_0TB-2_5in-PCIe-3_1-x4-3D1-TLC?q=SSDPE2KX010T7

Unless I’m missing something else, it seems that the drive is working fine now, correct? You can continue using those drivers as you are getting the expected performance of the drive.

Please let me know if there is anything else I can help you with.

Have a nice day.

Regards,
Diego V.
 

你好Diego V，
我认为在使用英特尔NVME驱动程序时，HGST PCIe SN260和英特尔P4500 U.2之间可能存在某种冲突。
看起来像这个包中的RSTE驱动程序可以阻止冲突。

I think there might be some sort conflict between HGST PCIe SN260 and Intel P4500 U.2 when using Intel NVME driver. look like the RSTE driver from this pack stops the conflict.
