Drive arrays and fault-tolerance methods Drive arrays The capacity and performance of a single physical (hard) drive is adequate for home users. However, business users demand higher storage capacities, higher data transfer rates, and greater protection against data loss when drives fail. Connecting - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 103
. If one physical drive has a larger capacity than other physical drives in the same logical drive, the extra capacity is wasted because it cannot be used by the logical drive. Drive arrays and fault-tolerance methods 103 - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 104
, or just array (denoted by An in the figure). Because all the physical drives in an array are commonly configured into just one logical drive, the term array is often used as a synonym for logical drive. However, an array can contain several logical drives, each of a different size. Each logical - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 105
, hardware-based RAID methods provide a much more robust and controlled fault-tolerance environment, so these alternative methods are seldom used. RAID 0-No fault tolerance A RAID 0 configuration provides data striping, but there is no protection against data loss when a drive fails. However, it is - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 106
(RAID 10) In RAID 1 and RAID 1+0 (RAID 10) configurations, data is duplicated to a second drive. When the array contains failed drives belong to the same mirrored pair. This fault-tolerance method is useful when high performance and data protection are more important than the cost of physical drives - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 107
half of the total drive capacity is usable for data storage. RAID 1 (ADM) and RAID 10 (ADM) In RAID 1 (ADM) and RAID 10 (ADM) configurations, data is duplicated to two additional drives. When the array contains only three physical drives, the fault-tolerance method is known as RAID 1 (ADM). Drive - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 108
to the same mirrored trio. This fault-tolerance method is useful when high performance and data protection are more important than the cost of physical drives. Advantages: • This method has the highest read performance of any fault-tolerant configuration. • No data is lost when two drives fail, as - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 109
is usually written to an online spare in a process called a rebuild. This configuration is useful when cost, performance, and data availability are equally important. Advantages: • Has Advanced Data Guarding NOTE: Not all controllers support RAID 6 (ADG). Drive arrays and fault-tolerance methods 109 - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 110
of the constituent drives. This method is most useful when data loss is unacceptable but cost is also an important factor. The probability that data loss will occur when an array is configured with RAID 6 (ADG) is less than it would be if it was configured with RAID 5. Advantages: • This method has - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 111
to occur when the drives are arranged into the configuration that has the largest possible number of parity groups. For example, four parity groups with the larger number of parity groups. RAID 50 is particularly useful for large databases, file servers, and application servers. Advantages: • - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 112
arranged into the configuration that has the largest possible number of parity groups used to store redundant or parity data than with non-nested RAID methods. Comparing the hardware-based RAID methods Not all controllers support all RAID levels. To support some RAID levels, HP Smart Array G6 and G7 - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 113
than 56 drives are used with RAID 6 (ADG). Selecting a RAID method Not all controllers support all RAID levels.

Most important - HP ProLiant ML10 | Configuring Arrays on HP Smart Array Controllers Reference Gu - Page 114
Neither of these alternative fault-tolerance methods supports online spares or automatic data recovery, nor do they support auto-reliability monitoring or interim data recovery.
