I'm trying
to get my hands on a DELQA or a DEQNA. Will
this require yet another re-shuffle of the cards, or can I
move the RQDX3 to the end and put the DELQA/DEQNA where
the RQDX3 is now?
You can physically put it there, but I'm not quite sure if it wants to
be closer to the front or closer to the back. You could put it there
and check performance... no timeouts means that its fine. I haven't
had the pleasure of playing much with DEC Ethernet devices.
I know it isn't per the configuration specs, but I always have any
ethernet adapter right after the processor/memory, then the default
system disk adapter (typically an RQDX3 on my machines).
I figure I want the ethernet adapter as close, electrically, as
possible to the processor/memory to maximize throughput (those
nanoseconds do add up ... :-) and the same for the system disk
interface.
I've never done any tests to see if there is actually a
noticable difference. Maybe one of these days...
