Re: Swap over network

In the days when SUN was 680x0 based, around the SunOS 3.x era if I remember
correctly, they support "network disks" which were used for diskless
workstation
swap space. Essentially they translated the block reads and writes to a
UDP based protocol. They abandoned support when they got swapping over NFS
working right.
If someone really wants to do this, I would suggest the approach of skipping
the idea of touching the swap code and instead write a block device driver
that talks to some server process as if it was a device. Doing it that way
it could be used for things other than swapping; including raid and striped
drives which span machines.
