You probably know Brantley Coile did ata over Ethernet. AOE is a simple protocol so the
client side driver is simple. He ran plan9 on his controller. One per rack. Basically you
have a storage area network. Adding disks becomes very easy. His company is back in
business if you want to buy some!
AOE is probably a better idea than FCoE, fiber channel over Ethernet, with its requirement
for a reliable transport. On the other hand, may be there is need for encrypted channels
all the way to disks.

So maybe Ron Minnich will remember this. Back in the days of 10Mbit
ethernet I was pushing for 100Mbit. Part of what I wanted was ethernet
all the way out to the disk drives. It was a little ahead of its time,
the idea was to run Linux on the general purpose processor and be able
to send the questions to the drive rather than slurping all the data
across and pawing through it on the main CPU. That was part of the
idea, the other part was power over ethernet and you need more space?
Just plug in a drive.
It's been over 20 years since I proposed that and things are starting
to look up a little. Western Digital made a version of what I wanted,
an ethernet attached drive with a key/value store on the drive. Not
quite there but closer. And I just stumbled across this:

Not sure how well that will work but it's interesting that people are
working on it.

Goldwyn I once thought of developing a computer where
everything from the

In effect replacing

purported to do just that but couldn't find any more info on it.
The Desk Area Network, perhaps?
