In reviewing the responses that I recieved on this posting,
alan_at_nabeth.cxo.dec.com replied with probably the most reasonable answer. I
have included his response below. Thanks to the others who responded. The
reason behind the posting (original post at bottom of msg.) is that I am
trying to put together a comprehensive parts list for an upcoming
maintenance contract bid. I have few older pieces of equipment and am trying
to determine the best part numbers to use.
Looking through the Systems and Options catalog to see where
the numbers appear, I'd guess that part of the difference is
the division selling you the part. DS- parts are from Storage.
SN- parts are from whoever handles workstations and servers.
Another subtle difference might be that SN- parts must be
bought with the initial system, but non-SN- parts could be
add-ons later.
All the FR- parts are from our old PC group and often have
real functional differences. For example, all the 4.3 GB
DS- disks have the same capacity and geometry, down to the
sector. It will also have been qualified on supporting
systems and if any problems were found, firmware changes
made to it. An FR- 4.3 GB SCSI disk comes pretty much from
the original vendor, with no qualification, no changes. A
Quantum disk may have a more or less sectors than the disk
from IBM.
Devices without the prefix, probably just predate the decision
to use the those prefixes.
For DS- and SN- parts it probably boils down to who gets
credit for the sale.
