Intel SSD 750 Series - VPD access through I2C

DBaye — Thu, 07 Dec 2017 21:30:16 GMT

Does the 750 support accessing the VPD through SMBus address 53h, per the SSD Form Factor Specification?

I am not getting an acknowledge when reading from that address.

2.5" U.2 Form factor, 400GB

Using an ARM® Cortex®-M4F Based MCU TM4C123G Tiva uController to read on the SMBus connected to the NVMe drive.

Our IPMI is needing to read the VPD data of the drive attached to our system.

This works with a competitors NVMe Drive, but it is an enterprise grade drive.

I wanted to know if the 750 series will work, or if we need to use something like the P3500 Intel series drives for support of SMBUS query on the NVMe interface.

Thanks

Hello Odb,

Thanks for your reply. Please allow us some time to investigate and confirm if this works with the Intel® SSD 750 Series or one of the NVMe drives on the Intel® DC SSD family.

We'll reply again as soon as we have news.

Best regards,

Hello Odb,

We have updates regarding your inquiry.The feature of accessing VPD via SMBus is not available on the Intel® SSD 750 Series, which is a consumer drive.As you suggested, you can use Intel® SSD Data Center Drives such as the Intel® SSD P3500 Series (as shown on the https://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/ssd-dc-p3500-series-product-spec.pdf Product Specification, section 2.10).Please bear in mind that the DC P3500/3600/3700 models have reached end of life (even though they are still available on the market), we advise to consider using newer models such as the 3D NAND based https://ark.intel.com/products/series/96935/Intel-SSD-DC-P4500-Series Intel® SSD DC P4500 and https://ark.intel.com/products/series/96947/Intel-SSD-DC-P4600-Series P4600.I hope this information will be useful for you. Let us know if we can help you with anything else.Best regards,Eugenio F.

Hi,

We had bought one card of DC P4600, and cannot find VPD capability enabled by PCIe function.

Does that mean we can only achieve the VPD through SMBUS?

Thanks

Logan

Hello Logan,

Yes, that is correct with the DC P4600 you can only achieve to read the VPD through the SMBUS interface. It is not enabled through the PCIe function.Hope this helps to clarify your question. Best Regards, Juan N.
