Systemd Working On "Storage Target Mode" Feature - Inspired By Apple macOS
Systemd Working On "Storage Target Mode" Feature - Inspired By Apple macOS
Yet another win for Systemd.
You're viewing a single thread.
Is this like booting over pxe? Is nvme tcp widely supported on motherboards?
No, this has nothing to do with your motherboard. Once you reach the boot menu you'll be able to pick your OS and alternatively
systemd-storagetm. If you chose the the latter then your disks will be available to other machines over NVME-TCP. Just like Apple.The problem of keeping comparing and doing analogies with apple shit stuff is that many of us have no idea what tech of magic apple does, so saying things like "just like apple" is a completely useless phrase that gives zero info whatsoever about anything.
It's probably why we're getting the tech almost 20 years late. Apple started doing this with FireWire
So I could mount and chroot over TCP to fix problems? Looks a little more complicated at this point than fstabbing an iscsi target, but I imagine that'll improve. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/managing_storage_devices/configuring-nvme-over-fabrics-using-nvme-tcp_managing-storage-devices
Sweet.
The PR aims to make it easy and simple.
So when it's booted it will just advertise the storage to the LAN over nvme-tcp protocol?
Not "booted", you won't be booting your full OS. It's just an option on the boot menu that launches systemd and a small program that does the magic and nothing else.
But is it running at the same time as a an OS or is it just a device without an OS running, sharing storage?
So share drive / simplified NAS, no?
Kind of... but you're directly accessing the hard drive like iSCSI does. Way less latency, no high (and slow) protocols like SMB are used.
NVMe/TCP is an extension of the NVMe base specification that defines the binding of the NVMe protocol to message-based fabrics using TCP. The rules for mapping NVMe queues, creation of NVMe-oF capsules, and the methods used to deliver the capsules over the TCP fabric are described in the NVMe/TCP Transport Specification. By binding the NVMe protocol to TCP, NVMe/TCP enables the efficient end-to-end transfer of commands and data between NVMe-oF hosts and NVMe-oF controller devices by any standard Ethernet-based TCP/IP networks. Large-scale data centers can use their existing Ethernet-based network infrastructure with multilayered switch topologies and traditional network adapters

SAN. Not NAS.
So NAS without any controls. Yay?
trivial to set up NAS with minimal overhead, plus you can boot any pc into this once it's standard, which would be nice for rescuing when you fuck something up: rather than fiddle around with rescue mode or digging out the drives you just boot into this mode and access the drives from your laptop or whatever.
It doesn't sound easier than ventoy tbh.
So like, grubd boot menu? And from there I can boot over a location on my nas for example? I set up ipxe a couple weeks ago but it couldn’t load over my thunderbolt to 10g nic. Would this help?
