hey mcleodnine, thx for the reply.
>non-SCA devices that use a physical adapter plate/plug?
i put four SCA 80-pin drives in scsi hotswap cradles that have 68-pin external interfaces.
the cradles are on the same bus as other 68-pin scsi drives that are not hotswapped nor hotswappable.
my concern is that hotswapping the sca drives might corrupt data or shorten the lifespan of 68-pin drives on the same bus since i do not believe that the same high-frequency (noise) filtering is specified for standard 68-pin u320 in comparison to SCA. i developed this notion by routinely finding references to spike-filtering in SCA specs but never in non-SCA specs.
having never fiddled with SCA before, i wonder if i'm just asking for trouble by mixing SCA with standard 68-pin drives.
as for interface robustness, each drive would be plugged in/out once every 8 days as i'm trying to store data offline in a chronological cascade in effort to minimize volatility. does this frequency sound unusually high, this seems like the kind of thing one learns (the hard way) by experience, which is something i surely don't have in this case.
