I'm working on implementing "amanda" for backup & recovery. We're in the process of switching from DDS (4mm) media to DLT. I believe that it would be useful to at least begin to plan for the (eventual) deployment of a stacker (though it need not be more elaborate than a simple "gravity" stacker). The vendor we're using (Andataco, evidently -- I'm still a little new here) has a couple of stackers with similar characteristics; each handles up to 7 DLT cartridges, but one is made by Quantum, and the other is made by Exabyte. Anyone have a feel for which is more likely to work adequately for FreeBSD 2.2.6-RELEASE? Here's the list of differences I've been told about (other than price, which is in the $8K range, with a difference of about $300 between the two -- close enough that price isn't a significant differentiator): Quantum ENC-6107-40S Exabyte EXB/18D-4TS Operator interface "control panel" LCD screen Bar Code Reader n/a available Dimensions WxHxD 8.9"x10.7"x27" 9.5"x22"x21.4" MTBF 30KHrs. 200KHrs. Cycles Between Failures 400K 1000K Each is a narrow single-ended SCSI device (in addition to the DLT4000 drive, which comes with the stacker), with a rated native xfer rate of 1.5MB/sec. (As alluded to above, I have no expectation that I'd be making any use of a bar-code reader.)
