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.
Yes That is what i had thought. Total of 4 HDD is 3.0TB, so i presume each HDD can be 750GB. But the IBM consultant insisted that they had not tested x3200 with 500GB SATA HDD. If the machine can support that, I wont have a problem installing CentOS using raid-1 with 2 x 500GB SATA drives.
I wonder who should I listen to. The website or the consultant.
Thanks
