英特尔SSD P4500是否支持VSS可变扇区大小功能？

嗨hmily_jian，
感谢您在英特尔社区发帖。
根据本指南，NVMe *驱动器使用可变扇区大小（VSS）技术。
由于英特尔®SSDDC P4500系列是NVMe *驱动器，它应支持VSS：在NVM Express *驱动器上更改可变扇区大小
本指南介绍如何使用英特尔®SSD数据中心工具（DCT）更改可变扇区大小，您可以尝试使用驱动器来确认它是否受支持。
我希望这些信息能回答你的问题。
祝你今天愉快。
此致，Diego V.

Hi hmily_jian,
 
Thank you for posting in the Intel communities.
 
According to this guide, the NVMe* drives use Variable Sector Size (VSS) technology. As the Intel® SSD DC P4500 Series is an NVMe* drive, it should support VSS: Change Variable Sector Size on NVM Express* Drives
 
This guide explains how to change the Variable Sector Size using the Intel® SSD Data Center Tool (DCT), you can try it with your drive to confirm if it is supported.
 
I hope this information answers your question.
 
Have a nice day.
 
Regards,
Diego V.

谢谢您的回复。
我使用isdct工具更改Intel Optane SSD DC P4800X上的SectorSize。
（我暂时没有找到P4500的磁盘。）
我发现扇区大小可以在512到4096之间切换。当我尝试将SectorSize更改为4160时。报告了一个错误。
所以我的问题是：英特尔SSD DC P4500 / P4510与英特尔Optane SSD DC P4800X相同，是否支持VSS功能，但它也不能
改为4160？
谢谢。
$ sudo isdct start -intelssd 0 -NVMeFormat LBAformat = 5 SecureEraseSetting = 0 ProtectionInformation = 0 MetaDataSettings = 0
警告！
您已选择格式化驱动器！
继续格式化？
（Y | N）：Y
格式化...（这可能需要几分钟才能完成）
- 英特尔Optane（TM）SSD DC P4800X系列PHKE736100RS375AGN -
状态：NVMe命令报告了一个问题。
并将SectorSize更改为4096.它成功了。
$ sudo isdct start -intelssd 0 -NVMeFormat LBAformat = 3 SecureEraseSetting = 0 ProtectionInformation = 0 MetaDataSettings = 0
警告！

Thank you for your reply.
I use isdct tool to change the SectorSize on Intel Optane SSD DC P4800X. (I haven't found the disk of P4500 for the time being.)
And I found  Sector size can be switched between 512 and 4096.  when I try to change the SectorSize to 4160. A mistake was reported.
 
So My question is :  Does the Intel SSD DC P4500/P4510 the same with Intel Optane SSD DC P4800X support VSS function, but It also can't
change to 4160?  Thank you.

我在英特尔SSD P4510上使用isdct工具更改扇区大小为4160。
据报道有一个错误。
$ sudo isdct start -intelssd 2 -NVMeFormat LBAformat = 5 SecureEraseSetting = 0 ProtectionInformation = 0 MetaDataSettings = 0

嗨hmily_jian，根据英特尔®SSDDCT用户指南（https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/Intel_SSD_DCT_3_0_x_User_Guide.pdf），LBA格式参数可以
是一个从0到驱动器具有的最大LBA格式数的数字，它被称为NumLBAFormats。
您可以使用show命令检查此参数，如下所示：isdct show -all -intelssd您应运行该命令以检查每个驱动器的可能格式数。
如果NumLBAFormats值为2，那么您只能使用0,1或2作为LBAformat参数.Regards，Diego V.

Hi hmily_jian,

According to the Intel® SSD DCT User Guide (https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/Intel_SSD_DCT_3_0_x_User_Guide.pdf), the LBAformat parameter could be a number from 0 to the maximum number of LBA formats the drive has, which is referenced as NumLBAFormats. You can check this parameter with the show command as follow:

isdct show -all -intelssd

You should run that command to check the number of possible formats for each drive. If the NumLBAFormats value is 2, then you can only use 0, 1 or 2 for the LBAformat parameter.

Diego V.

祝你今天愉快。
谢谢您的回复。
我发现英特尔SSD DC P4510的NumLBAFormats = 1.仅支持512和4096扇区大小。
所以我的问题是：为什么P4510不能支持4160个扇区？
谢谢。

Have a nice day.  Thank you for your reply.
 
I found Intel SSD DC P4510 's  NumLBAFormats = 1.  only support 512 and 4096 sector size.
 
So my question is: Why P4510 can not support 4160 sectors?
 
Thank you.

嗨hmily_jian，请让我调查你的问题。
我会在这里发布任何我能找到的关于它的信息.Regards，Diego V.
