logical drive will fail depends on the RAID-level setting and on the number and type of physical drives in the array. If the logical drive does occurs when the two failed drives are mirrored to each other. As the total number of drives in the array increases, the probability that the only two failed - HP A9890A | Configuring Arrays on HP Smart Array Controllers Reference Guide - Page 93

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 - HP A9890A | Configuring Arrays on HP Smart Array Controllers Reference Guide - Page 95
drive. For data in the logical drive to be readable, the data block sequence must be the same in every stripe. This sequencing process is performed by the array controller, which sends the data blocks to the drive write heads in the correct order. A natural consequence of the striping process is - HP A9890A | Configuring Arrays on HP Smart Array Controllers Reference Guide - Page 96
alternative fault-tolerance methods that are sometimes used are also described ("Alternative faulttolerance methods" on page 103). However, hardware-based RAID methods provide a much more robust and controlled fault-tolerance environment, so these alternative methods are seldom used.

amounts of noncritical data (for printing or image editing, for example) or when cost is the most important consideration. Advantages: • Has the highest write performance of all RAID methods. • Has the lowest cost per unit of stored data of all RAID methods. • All drive capacity is used to store - HP A9890A | Configuring Arrays on HP Smart Array Controllers Reference Guide - Page 98
without incurring data loss, as long as no two 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. NOTE: When there are only two physical drives in the array, this fault - HP A9890A | Configuring Arrays on HP Smart Array Controllers Reference Guide - Page 99
is usable than with RAID 1+0-parity information requires only the storage space equivalent to one physical drive. Disadvantages: • Has relatively low write performance. • Data is lost if a second drive fails before data from the first failed drive is rebuilt. Drive arrays and fault-tolerance methods - HP A9890A | Configuring Arrays on HP Smart Array Controllers Reference Guide - Page 100
Guarding NOTE: Not all controllers support RAID 6 (ADG). RAID 6 (ADG), like RAID 5, generates and stores parity information to protect it was configured with RAID 5. Advantages: • This method has a high read performance. • This method allows high data availability-Any two drives can fail without loss - HP A9890A | Configuring Arrays on HP Smart Array Controllers Reference Guide - Page 101
. However, less data can be stored on the array with the larger number of parity groups. RAID 50 is particularly useful for large databases, file servers, and application servers. Advantages: • Higher performance than for RAID 5, especially during writes. • Better fault tolerance than either RAID - HP A9890A | Configuring Arrays on HP Smart Array Controllers Reference Guide - Page 102
the larger number of parity groups. RAID 60 is particularly useful for data archives and high-availability solutions. Advantages: • Higher performance than for RAID methods.
