I have a HP DL360 G5 with an addon p800-controller with battery-backed cache, a msa70-cabinet and 11 2,5" sas-disks @ 15K in raid-6 and one hotspare. The controller has 512 MB and is performing satisfactory. This is on FreeBSD 7.0 release and postgresql 8.3.1. I've heard many positive remarks on areca's raid-controllers as well, vendor-support on FreeBSD and good performance. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner.
