It is _not_ hardware RAID, but FRAID (i.e., 100% software).

Understand by "array" you are talking about "regular looking ATA drives"
that have a specific disk organization the FRAID (100% software) driver
can understand.

You either need to load an equivalent software driver under Linux (which
may or may not be possible), or use the newer kernel 2.6 LVM2-DM (Device
Mapper) which now has some FRAID meta-data support.  I've found both to
be largely _broken_ and untrustworthy in general, but I'm hopeful for
the latter in the future.

Correct, because the vendor has produced 100% proprietary, binary-only
modules for _specific_ kernel versions.  There is no GPL driver, there
is _no_ general, linkable driver (AFAICT).  FRAID has always suffered,
and will always suffer, from the fact that 100% of the RAID logic is in
the software, and that software is almost always licensed from a 3rd
party and proprietary.

The Device Mapper approach is interesting though.  Instead of relying on
the vendor's proprietary driver/logic, it can read the meta-data and use
the generic software RAID built in the Linux kernel -- by-passing any
need for the proprietary FRAID software/logic.

The drivers won't even work on Fedora Core and even some newer Red Hat
Linux kernel updates.

Can you send me a link?  I'd be interested in knowing what they offer.
