Hi ppl . I am getting a IBM x3200.. This machine can only support up to 4 x 250GB SATA. I need to have a usable space of 500GB and mirror it to other 500GB. IBM proposed me to get 2 RAID cards. Do you guys think i can do raid 0 on the first 2 x 250GB HDD and raid 0 on the second 2 x 250GB hdd, both on hardware raid and then during the installation of centos 5, i raid 1 on both the 2 sets of hardware raids? Thanks
