namespace operation on optane 900P? #346
I have a intel 900P installed in a Ubuntu 16.04 machine (with nvme 1.0 kernel module loaded by default)
I saw the output of the fdisk saying it has 512 byte sector size and i/o size:
Any comments or suggestions are appreciated!
If this did support that format, there should have been an 'lbaf' with an 'lbads:12', and then you can select that with an "nvme format /dev/nvmeX -l '. I'm not sure if this one supports 4k or not. The optanes I have do support that, but they're slightly different than the 900P.
In any case, if you align IO and partitions to 4k, you should get the same performance out of this as if it were formatted to 4k physical sectors.
hi Keith, thanks for the explanation
