104 Appendix A: Embedded SATA RAID Technology for the Altos G310 Mk2 Configuring arrays Configure the physical disk drives in arrays. An array can consist of one to four physical disk drives, depending on the RAID level. A RAID 0 array can consist of one to four physical drives, while a RAID 1 array consists of two. Configuration strategies You have two choices when creating a RAID array. • Maximizing fault tolerance You can maximize fault tolerance to protect against loss of data by using mirroring. Use mirror configuration (RAID 1) to attain this objective. • Maximizing logical drive performance You can maximize logical drive performance by using striping. Select striping configuration (RAID 0) to attain this objective. Assigning RAID levels Only one RAID level can be assigned to each array. The table below displays the drives required per RAID level. RAID Level 0 1 Minimum number of physical drives One Two Maximum number of physical drives Four Two The factors you need to consider when selecting a RAID level are listed in the table below:
