The CAM Target Layer (CTL) is now available for testing. I am planning to
commit it to to head next week, barring any major objections.
CTL is a disk and processor device emulation subsystem originally written
for Copan Systems under Linux starting in 2003. It has been shipping in
Copan (now SGI) products since 2005.
It was ported to FreeBSD in 2008, and thanks to an agreement between SGI
(who acquired Copan's assets in 2010) and Spectra Logic in 2010, CTL is
available under a BSD-style license. The intent behind the agreement was
that Spectra would work to get CTL into the FreeBSD tree.

- Note that the ramdisk backend is a "fake" ramdisk. That is, it is
backed by a small amount of RAM that is used for all I/O requests. This
is useful for performance testing, but not for any data integrity tests.
so, If I read this correctly, I should be able to export a fusion-io
flash card with
ctladm create -b block -o file=/dev/fio0 ??
- To add a LUN with the block/file backend:
truncate -s +1T myfile
ctladm create -b block -o file=myfile
ctladm port -o on
