Have a good day!

Does Intel SSD P4500 support VSS(Variable Sector Size) functions?

If not,Why? I known that SSD P3500/P3600/P3700 series are support VSS functions.

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: https://www.intel.com/content/www/us/en/support/articles/000016238/memory-and-storage/data-center-ssds.html 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.

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.

$sudo isdct start -intelssd 0 -NVMeFormat LBAformat=5 SecureEraseSetting=0 ProtectionInformation=0 MetaDataSettings=0

Formatting...(This can take several minutes to complete)

- Intel Optane(TM) SSD DC P4800X Series PHKE736100RS375AGN -

And change the SectorSize to 4096 .It was succeed.

$sudo isdct start -intelssd 0 -NVMeFormat LBAformat=3 SecureEraseSetting=0 ProtectionInformation=0 MetaDataSettings=0

And I use isdct tool change sector size to 4160 on Intel SSD P4510. A mistake was reported.

$sudo isdct start -intelssd 2 -NVMeFormat LBAformat=5 SecureEraseSetting=0 ProtectionInformation=0 MetaDataSettings=0

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 -intelssdYou 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.Regards,Diego V.

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.

Hi hmily_jian,

After investigating about this concern, I have received confirmation that indeed, the Intel® SSD DC P4510 Series supports only 512 and 4096 sector sizes. The support for the other options was not implemented for this drive model.Regards,Diego V.

Intel DC P4510

Hello,

i have the same problem to change the sector size. When i use the command:

isdct show -all -intelssd

there are no NumLBAFormats shown .. the line is missing.

The Intel DC P4510 use 512 and i want it to change to 4096 (4K) sector size. When i want to

isdct start -intelssd 0 -NVMeFormat LBAformat=1 SecureEraseSetting=0 ProtectionInformation=0 MetaDataSettings=0

It only shows

Invalid LBA Format

Thanks and best regards

Andre

Hi Andre,

Could you please save the output of the isdct show -all –intelssd command in a file and upload it here so that I can take a look at it?I'll be waiting for your response.Have a nice day.Regards,Diego V.

Thank you for your reply.

I know this conclusion that Intel® SSD DC P4510 Series supports only 512 and 4096 sector sizes.

My question is:

1、What are the specific technical reasons for that Intel® SSD DC P4510 Series supports only 512 and 4096 sector sizes.?

2、Which new NVMe SSD products will support more variable sector size such as 4160&4224 bytes in the future?

Thank you!

Hi hmily_jian,

512 and 4096 are the two most common sector sizes in Windows* and Linux*, therefore they are the ones that are currently supported.We have no information about future releases with additional sector size options at this point.Regards,Diego V.

Hello Diego,

It worked. After I removed the second controller It also shown NumLBAFormats=1 after the restart. Changing the sector size worked immediately.

Thank you!

Best regards

André
