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

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

Any other favorites?If you will search the list archives, 3Ware has been recommended, many times, in recent months, on this ML. Sometimes, it's worth ordering from overseas and paying for shipment and customs. I've ordered many things from the USA and it is incredibly rare that something has arrived DOA, in the past 12 years. If it is DOA, then you are without a warranty and in deep stuff.... Look into 3Ware!
