  • Page 68: Raid Levels

    The RAID level determines how the controller reads and writes data and parity on the drives. The Sun StorEdge T3 and T3+ array can be configured with RAID level 0, RAID level 1 (1+0), or RAID level 5. The default configuration is a RAID level 5.

  • Page 69: Raid 0

    3.2.2.1 RAID 0 Data blocks in a RAID 0 volume are striped across all the drives in the volume in order. There is no parity data, so RAID 0 uses the full capacity of the drives. There is no redundancy; however, if a single drive fails, all data on the volume is lost. shows the data layout in a RAID 0 volume.

    5.2.2 Power and Cooling Units The power and cooling unit has two active power sources: standby and primary power. Standby power, which is used to power the microcontroller on the interconnect card, is activated when AC power is present. Primary power, which is used to power all remaining circuits and disk drives, is activated when AC or battery power is present and the power switch is on.
