DEC HSC50 disk/tape server query

[#J.MONTGOMERY]

I just received a brochure from DEC describing briefly the HSC50
intelligent disk/tape server.  I wonder if anyone on the net can
comment on this unit, in particular

1)	Has amyone written (or thought about writing) a driver for it?

2)	What performance enhancements (or other benefits) might be
	gained from it on a VAX-11/780, with an RA-81 disk, running UNIX?

Please reply by mail.  If anything interesting comes back I will
post it to this newsgroup. Thanks in advance.
