i was actually looking at one of these.
For my simpler needs, data protection is important but there isnt lots of it
so 2 x 20 gig disks mirrored is heaps. I would like to keep the uptime up,
so was thinking of this solution, anybody tried one? Its for my web server
with all of a 128k connection so sucky performance isnt an issue as its
bugger all hits.
However for another job Im thinking of elsewhere (a 2 node cluster) though
it would be a disaster. 3meg a sec just wont cut it, i can get 16 meg off a
second hand scsi setup for the same dosh.

Dont buy it! It as simple as that. 1 year ago i bought one of those
bastards from promise and its slooow. Im running it as filer on a
debian 3.0 system filesystem xfs and i havent been able to push it to
a sustain throughput on more than 3MB/sec. This is with 8 60GB IBM deskstar
7200rpm disks in raid5. Recently a disk crashed on me and the hole
array went offline allthough the manual says it should continue to
function. NOT TRUE! I relplace the broken drive with a new and the
promisearray began to rebuild i thought i where homesafe..... After
rebuilding in 15 hours the array went offline again and nothing i did
got it back?? I called localshop where i bought it nobody could help
me they suggested that i contacted promise in netherlands. Story
continues.....
Promise in netherlands where quit helpfull but what they suggested got
me pulling out my hair!!! (what i have left of it). They suggested
that i deletede the array, created a new and saved it then just after
saving it i had to pull out the powercord in the back so the array
wouldn't initialize. I would not belive what i was hearing. Pulling
out powercord while the array is initializing sounds like a hugh hack
to me but i did it just because i didnt knew what else to do. It
actually worked so now im back to the good old sloooow promisearray
and after a xfs_repair my filer was up and running again.
Next time i have to buy ideraid ill try 3ware for sure.
