Last night we ran into trouble with the 3ware controllers we have (9650SE-8LPML) because we couldn't create a larger RAID5 than 1.99TB. We are going to use FreeBSD 8.0 and Bacula, but first we obviously need to create a working RAID. My questions are: - Are HighPoint RocketRaid controllers a good alternative to 3ware controllers? Are RocketRaid controllers true hardware RAID? - What should we look for in a RAID controller spec to see that it has support for larger than 2TB RAIDs? I've been looking at these: http://www.highpoint-tech.com/USA_new/series_rr2300.htm http://www.highpoint-tech.com/USA_new/series_rr3500.htm Any FreeBSD recommendations? Or perhaps for another 3ware controller? We're using SATAII drives. Thanks for your help! Best regards, Andreas
