Does Intel DC P3600 supports SGL?

[srama16]

Hi ,

We are using Intel DC P3600 800G drive in our storage array, does this SSD drive supports SGL feature?.

we are using intel SPDK while debugging we found the NVMe controller doesn't support SGL

(gdb) p ns->ctrlr->flags & SPDK_NVME_CTRLR_SGL_SUPPORTED

$1 = 0

Is there any setup or settings which we are missing to set the device to support SGL?

Please find the drive information below and let me know if you need more information.
