interesting observation: when i first set up the diskless fileserver
at coraid, we had a mirror of the worm in another building across
an awful wireless connection. we had no more than 1mbit.
at first i was a little worried about this, but then i realized that
128k/s * 86400s/day is 10.5gb/day.
btw, with aoe, you should saturate the network—125 mb/s/interface
for gbe so a typical el-cheepo computer these days can do 250mb/s
over aoe without breaking a sweat. of course you'll get 10x that with
10gbe.
i agree with charles, network attached, or even internet-attached
storage seems like the way to go. for internet-attached storage,
the amazing imbalances of very slow last-mile networks/very cheep
mass storage and the power of slow networks over time lead me
to think there are some very interesting engineering tradeoffs to
be made.
