I'm afraid I don't understand SCSI buses as well as I thought then
;-) Why does this create a bottleneck for internal HD->VXA writes?
The internal drive is Fast SCSI-2 (and benchmarks in the 8 MB/s
read/write range with HDT 4)... so it seems like the drive itself
should not be slowing things down. Also, ignoring the internal drive
tests, in normal network backup use the VXA still performs more
slowly, anywhere from 25%-50% slower than the DDS-2 (identical
backups, I'm running backups to each device nightly).
Please feel free to talk to me like I'm an idiot ;-) because
apparently I don't understand this as well as I thought ;-)
Thanks,
