Re: Near Line Storage - 2 Terabytes 10 Target Servers

["Karl R. Balsmeier" <karl_(_at_)_sfdata_(_dot_)_net>]

I am already using a 30 tape library and have broken the jobs up.  I'd
rather take the user data and move it to near line storage instead of
tape.

What I am asking is if anyone knows of something other than tape, like a
sort of poor man's SAN, where I can move data quickly [far faster than
tape], say, something better than a LaCie drive, that can be connected to
an OBSD machine.

"Near Line" implies it's not on tape, but a great way to quickly pull the
data down to a large drive or other device.  Thanks for the input so
far...  Just thought i'd check within the community for a design that uses
openbsd, since i'd rather throw money at that, as it's money well spent.
