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?
IBM's website says you can use 500GB and even 750GB drives with their 'simple swap SATA raid'. whatever.
If you're using 4 x 250GB, have IBM configure it as a primary and secondary raid-1 (2 drives each). then, when you install CentOS, tell the centos installer to add both of those RAID volumes to a single VolGroup00 with LVM, then create your file systems on the resultant LVM. LVM will stripe the data across the two mirrors, so you'll get the equivalent of a raid10
