I suspect you must be conflating several different storage products. Are you saying https://cloud.google.com/compute/docs/disks/local-ssd devices talk to the host through a network (say, ethernet with some layer on top)? Because the documentation very clearly says otherwise, "This is because Local SSD disks are physically attached to the server that hosts your VM. For this same reason, Local SSD disks can only provide temporary storage." (at least, I'm presuming that by physically attached, they mean it's connected to the PCI bus without a network in between).
I suspect you're thinking of SSD-PD. If "local" SSDs are not actually local and go through a network, I need to have a discussion with my GCS TAM about truth in advertising.
I don’t really agree with assuming the form of physical attachment and interaction unless it is spelled out.
If that’s what’s meant it will be stated in some fine print, if it’s not stated anywhere then there is no guarantee what the term means, except I would guess they may want people to infer things that may not necessarily be true.
"Physically attached" has had a fairly well defined meaning and i don't normally expect a cloud provider to play word salad to convince me a network drive is locally attached (like I said, if true, I would need to have a chat with my TAM about it).
Physically attached for servers, for the past 20+ years, has meant a direct electrical connection to a host bus (such as the PCI bus attached to the front-side bus). I'd like to see some alternative examples that violate that convention.
The NIC is attached to the host bus through the north bridge. But other hosts on the same ethernetwork are not considered to be "local". We dont need to get crazy about teh semantics to know that when a cloud provider says an SSD is locally attached, that it's closer than an ethernetwork away.
