Looks like the Intel 4510 support namespaces as well.
Describes support of multiple namespaces in Data Center drives.
my Oracle F320 (Samsung 1725a) does not support them:
the key indicator seems to be this :
# nvme id-ctrl /dev/nvme1 -H
oncs : 0x6
[5:5] : 0 Reservations Not Supported
[4:4] : 0 Save and Select Not Supported
[3:3] : 0 Write Zeroes Not Supported
[2:2] : 0x1 Data Set Management Supported
[1:1] : 0x1 Write Uncorrectable Supported
[0:0] : 0 Compare Not Supported
I will use two of those drive to split them in cache tiers, to create 4 Disk groups in vSAN.
