[fa.info-vax] uVAX Disk Drives

ART@ACC.ARPA (Art Berggreen) (09/11/85)

I've just gotten through the wonderful experience of building uVMS 4.1
on much too small a disk (10Mbyte RD51).  I'm considering replacing the
drive with an RD52 (30Mbyte) or preferably an RD53 (70Mbyte) and was
wondering if anyone has any comments requarding reliability, performance,
etc.

Also, does anyone have any experience with 3rd party disk controllers
for uVAX-II with small winchesters in the RD52, RD53 size range.

How about waiting until the KDA-50 appears this fall?  It should be a q-bus
implementation of the UDA-50, to handle RA-class drives.  With the new quad
high stack of RA-81s in a cabinet...  Or maybe get the quad-high cabinet,
only three disks, and rack-mount your uVAXII in the top slot - CPU and
storage in a pretty tiny footprint.  The fourth disk cable on the controller
could be to another disk that was dual-ported with another *DA-50 on another
machine...

Has anybody heard any reliable rumors about the KDA-50's introduction?
