NVMe over TCP support?

[jsterr]

Hello Community,

Does Proxmox VE and Proxmox (subscription wise) support NVMe over TCP Storages? Are there any prerequisites to meet?
I dont have any experience in nvme over tcp yet. As far as I know NVMe over TCP requires "nvme-cli" and some manual configuration right?

Thanks Jonas

There is no PVE integrated tooling, but aside from that it would work pretty much the same as any shared lun (eg, iscsi.)

So you also cant snapshot like in iSCSI?

all the same limitations apply.

WRT snapshots, there is a workaround but its a bit of a pain; instead of mapping luns to PVE and have PVE manage the store, you map the lun DIRECTLY to a guest, and use the storage snapshot facility. You'd need to build the quiescense orchestration in-guest but it can be done.

Yes, PVE works excellently with NVMe/TCP. It comes with recent enough Kernel with stable NVMe/TCP support.
We test and support iSCSI and NVMe/TCP equally for our PVE customers.

iSCSI vs NVMEoTCP is just a different protocol, functionality is the same.
