Hi Jack,

HP recommends no more than 4 drives per single ended SCSI controller.  Even
if you fudged that a little, 10 is *way* too many.  You would likely end up
with serious disk I/O performance problems.  Are you sure about the slot
space??  Isn't there another s/e SCSI controller used for the internal disk
and the DAT drive?

controller has 4 devices presently connected to it.  I would like to max.
out each system by adding 3 more 2 gig drives to each 6000 system.  That
would make a total of 10 devices per single ended controller.  My problem
is that I do not have any additional slots available to add more
controllers and fast wides are not an option.  So my question is, how many
devices are supported on a Single Ended SCSI controller and how do I set
the SCSI address switches??
