SubjectRe: DE and hot-swap disk caddies

Hi Chuck,

You have me laughing and I love it, your signature!

What you are referring to is an bridge to a backplane, here is the voodoo
electronics. If you check, I suspect that each drive is master mode, and
the tailgate generates the ID; where as the interface is more or less
SCA-SCSI. SCA is an interface w/ all the tristating buffers intergrated.
