Of Course 3GBit is cheaper than 6GBit- 6GBit is new. > If you build machines with 24, 36 or even more disks, this > can become quite an issue. if you have so many disks I would recommend a chassis with expander Backplane (like Supermicro 846E16). You have 4x6GBit to the backplane which should be enough even if you connect 24 HDD. > MF> Integrated Raid is currently not supported, but they work as HBA wi= th > MF> 8.2-STABLE. >=20 > I guess the integrated raid is the problem when it comes to the price. = I'm > looking for something without integrated raid, which is usually much > cheaper. Thanks for the hint, anyway. LSI 3081E-R can also do integrated raid as well- 3801E with external connectors can't do this because of the missing NVRAM Chip. IMHO integrated raid it is supported in FreeBSD. Regards, Michael!
