SCSI device on VAXstation 3100

The Question is:

 I am sorry for this question as it is not purely vms
more of a hardware question but i have been unable to
trace a contact for the info.

 I need to know the most devices able to be attached to
the scsi bus on a microvax 3100-90:
 I have 2 busses, dka*: and dkb*:

 once again i am sorry for this question,but i need to
know rather urgently.

Many Thanks,

The Answer is:

    3 scsi devices internally on buss a (or 2 plus floppy or tape depending
    on enclosure).

    Externally you can theoretically conect up to 7 devices but are limited
    in the extenal length of the buss. If you use a storageworks shelf, you
    can run 7 devices.  If you use the older SA12 and 16 2 drive
    enclosures, you can have two enclosures, perhap 3 if you keep the
    cables real short...  only 2 is supported though.
