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.
When lenity and cruelty play for a kingdom,
the gentlest gamester is the soonest winner.
