Buchholtz) Newsgroups: comp.sys.sun Subject: More than two drives on an Xy7053 Keywords: Hardware Message-ID: <1819@brazos.Rice.edu> Date: 29 Sep 89 16:01:44 GMT Sender: root@rice.edu Organization: Sun-Spots Lines: 17 Approved: Sun-Spots@rice.edu X-Sun-Spots-Digest: Volume 8, Issue 145, message 11 of 14 It is possible to hang up to four disks off of an Xy7053 (SMD-4) controller, but I remember hearing somewhere that you take a big performance hit if you hang more than two drives off of one controller. I have two Hitachi DK815-10s and a new CDC Sabre 1.2 Gig. I have a Xylogics 7053 (Sun SMD-4) controller, and I'm wondering whether to buy a new set of cables, or another 7053 to support the new disk. Any advice or experience will be greatly appreciated. Email me and I'll summarize to the news-group. Thanks, Charles H.
