1.2 Terminology The document uses the following terms: RAID RAID is the abbreviation of “R edundant A rray of I ndependent D isks ” . There are different RAID levels with different degree of the data protection, data avai lability, performance to host environment. PD The P hysical D isk belongs to the member disk of one specific volume group. V[...]
