Re: Sata vs SCSI raid array

hi

we've been using some of the AC&NC units for a few years both direct
fibre channel attach and fabric attach with mixed success. we use 2
different units an older one 14 bay and a newer 16 bay.

for the most part i'd say they are very stable.

only one major data loss to speak of and that was due to a bad firmware
upgrade which redesignated a RAID 5 LUN as a RAID 0. unfortunately it
took 2 hours convincing support that it was a firmware issue. they fixed
it and the unit has since been stable. latest firmware update went
without issue.

getting what we paid (or didn't) pay for on the support side i guess.
pricing was reasonable when we purchased them although now i think the
ax100i might be a good deal, all things considered.

we also have recently installed a nexsan satabeast. pretty stable so
far. time will tell.
