When we were hooking up the Fujitsu 2372k's to our new Xylogics 753 and
ran dead into the Xylogics firmware problem ( couldn't put the 753 in with
the 451), we jerry-rigged ome of the 2372k's onto the 451.

This placed a Hitachi 815-10 and a Fujitsu 2372k on the same Xylogics 451
controller in a 4/280.  Everything worked fine (great!), until I tried to
move the Fujitsu back to the 753.  The defect list got trashed.  Boy, did
I learn the hard way to make backups of the defect list!!!

Conclusion:

I saw no problems whatsoever while the Hitachi and the Fujitsu were both
located on the 451 controller.
