12. The first step in creating a RAID storage configuration is to configure physical disk drives in arrays As defined for Embedded MegaRAID Software an array is a group of one to eight physical disks that is seen by the host computer system as one large disk drive or logical drive Only one RAID level can be assigned to each array e A RAID O array consists of one to eight physical drives e A RAID 1 array consists of two physical drives e A RAID 10 array consists of four six or eight drives Note Some hardware configurations do not support eight disk drives So depending on the hardware the actual maximum number of drives for RAID 0 and RAID 10 arrays can be fewer than eight Important LSI recommends that you do not use both SAS and SATA drives in the same array Using different drive interfaces in this way could cause unpredictable behavior decreased performance an increased error count and decreased Mean Time Between Failures MTBF You can use either of these two strategies when creating RAID arrays and logical drives e Maximize Fault Tolerance You can maximize fault tolerance to protect against loss of data by creating a RAID 1 array with mirroring Overview Version 1 0 Copyright 2006 by LSI Logic Corporation All rights reserved All data is written to the primary disk in the array and is also written mirrored to a second disk e Maximize Logical Drive Performance You can maximize logical drive performance b
