Hi Sorry to cross-posting. I don't knwon which mailing-list I should post this message. I'll would like to use FreeBSD with ZFS on some Dell server with some MD1200 (classique DAS). When we buy a MD1200 we need a RAID PERC H800 card on the server so we have two options : 1/ create a LV on the PERC H800 so the server see one volume and put the zpool on this unique volume and let the hardware manage the raid. 2/ create 12 LV on the perc H800 (so without raid) and let FreeBSD and ZFS manage the raid. which one is the best solution ? Any advise about the RAM I need on the server (actually one MD1200 so 12x2To disk) Regards.
