As usually, major rewrites tends to introduce some bugs. So, I've
released 1.3.5 as update:

You can do this from user level with pretty good results. I remember a
paper that appeared in either a Usenix NT workshop or a MSJ that talked
about doing it. Building a filesystem driver in the kernel requires getting
the FSDK which, last I checked, was licensed.

Another company to look at is Yottayotta (www.yottayotta.com).
They just announced their first products last November, and there
isn't much hard product info online yet. For the arena they're
targeting, though, 70TB would be an entry level system.

Emulex, as they don't offer source or documentation for the hardware.
You may want to look at a Qlogic-based controller instead.

Ohhh, fat
The crock in these trunking schemes is all the trouble and effort expended
to avoid re-ordering frames across the trunk bundle. This is why you
see things like the hashing techniques so that an individual flow of
traffic doesn't get reordered because it always is serialized over the
