Hello TechNet ... I am about to draft an LVDS SCSI Backplane; having
taken on board several papers on Transmission Line theory, Controlled
Impedance PCB's and the like, my understanding is that I am not allowed
to stuff a pile of RAID Disks on a Backplane at a 2" spacing - got to
make 10" or so of track between each. I believe the relevant problem is
termed 'stub clustering'.
Can anyone point me at further works to throw some light on this
subject, the relationship between stub lengths and stub spacing? My gut
feeling, (after having seen some products currently shipping) is that
one could do a 'dirty' implementation and accept a lower useable cable
length outside the cabinet ... down to say, 3 metres from 10 (yes I know
it's in metric ... us poor Brits got stuck between Imperial and Metric
about 15 years ago and have been working with both measurement systems
ever since.)

Hope someone can help ...    Regards -    G/.
