We have purchased two stock HP ML350e Gen8 servers. Ubuntu 12.04 is to be installed in those. The stock, base unit have provision for 6 hard disks for creating RAID in which, one is filled with 500GB Hard disk and others with blank plates. We are planning to buy hard-disks and hard-disk bays for creating RAID array.
I am confused with software RAID, hardware RAID and RAID levels. Kindly help me. Which RAID level is commonly used in IT firms and is most reliable.
Kindly guide me with what all steps are there for creating RAID in HP Proliant ML350e Gen8 server? I am new to RAID configuration. Kindly answer in detail.
