This drive looks cool but I’m trying to find out if I can create additional NVMe namespaces for managing storage for VMs. This doesn’t seem to be very easy information to locate! I can’t tell from the manual how many namespaces are supported.
I don’t have any NVMe drives at the moment so I can’t experiment with these commands, but it seems that running (on Linux, with nvme-cli):
nvme id-ctrl /dev/nvme0 | grep ^nn
will return the number of supported namespaces for a drive, at least according to:
If anyone has this drive and is happy to do a little investigation (or just know some other way I might find out) I’d really appreciate it.
No they don’t support namespaces.
root@zephir:~# nvme id-ctrl /dev/nvme0 | grep -E "^nn|^mn "
mn : Seagate FireCuda 530 ZP2000GM30013
nn : 1

On the other hand the micron 7400 pro M.2 22110 supports nvme namespaces:
root@zephir:~# nvme id-ctrl /dev/nvme3 | grep -E "^nn|^mn "
mn : Micron_7400_MTFDKBG3T8TDZ
nn : 128

Having a FireCuda 520 subject to this fine issue (abridged: fstrim impossibly slow) - have you experienced the same issue or anything objectionable on the 530 from Linux?
(let’s leave it implied that the fix was worse the problem, yet 530’s are still a better price than some)
