Hello,

I'm looking for information concerning 
VAX 4000-700A High Speed DSSI Adapter (KFDDB-AA).

Any information is appreciated (especially performance).

Please mail to: nilsson@front.se.

Thanks in advance!

Performance of the KFDDBs should be the same as the integral DSSI adapters, as
they also connect directly to the CPU bus.  I've seen a report of a system in
our labs with the two integral DSSI adapters plus two KFDDBs (for a total of 4
DSSI adapters) doing a total of 13 MB/sec (out of 3.75x4 = 15 theoretical) and
5,000 QIOs/second using RF drives.
