for this to take off in any big way, i think someone needs to be
"sold" the idea where it would make a significant impact - a dramatic
improvement in profitability, to give them that competitive edge.
i figured that the much simpler way would be web service farms of
LAMP/LAPP systems [with oracle's reputation going to shit i prefer to
promote postgresql], where the ARM systems cover the LA.P and the
standard big-iron systems cover the SQL server part. this would be
highly effective in areas where high latency is not a real big issue.
the nice thing about this is that web server farms already recognise
and deploy the concept of round-robin DNS or HTTP proxy redirection in
order to farm out the queries to individual web front-ends.
where was that article last week which explained the horrendous
amount of power being wasted on x86 systems just *idling*? those
systems have to be spec'd to peak throughput. embarrassing or what.
just so we can get at "da clowuhhd". a pack of 5 ultra-low-power ARM
systems replacing one beefy x86 system would have both performance
*and* power usage wayyy better.
i'm intrigued about the NDAS idea though. i looked up NDAS, there's
a company called ximeta - they apparently released GPL linux kernel
drivers for their proprietary protocol, but code.ximeta.com has been
taken offline, since.
what did you have in mind, and what, overall, is the problem that
you're looking to solve? are you envisioning little ARM computers
with SATA drives (rack-mounted, 1U, Qty 16 per rack), several of these
per cabinet, then being turned into a "Global File System", like this:
