high reliability. RAID technology separates your data and your disk drives into disk arrays and disk volumes. These divisions are used to safeguard data and to make the most efficient use of your disk drive space. Two RAID types are supported on the XP512 and XP48. Which RAID type you need depends - HP StorageWorks XP512 | HP SureStore E Disk Array XP512/XP48 Owner's Guide - Page 96
mirrored copy. Writes to the array in RAID0/1 mode occur the same as explained for RAID1. The primary side is destaged first. After the primary data has been successfully destaged, the secondary data is destaged to the mirror drive mechanisms. 96 HP SureStore E Disk Array XP512/XP48: Owner's Guide - HP StorageWorks XP512 | HP SureStore E Disk Array XP512/XP48 Owner's Guide - Page 97

supported on your XP disk array, but it is a preface to understanding RAID5, which is supported. RAID3 allows data to be split and distributed on two or more disk drives using striping. Because two or more disk Disk Array AP1 BP1 CP1 DP1 98 HP SureStore E Disk Array XP512/XP48: Owner's Guide - HP StorageWorks XP512 | HP SureStore E Disk Array XP512/XP48 Owner's Guide - Page 99

that is executed to update the parity data. This would make it impossible to perform parallel I/O processing because the parity disk would always be busy with the first block of data. This is a problem with RAID3 that RAID5 has alleviated. 100 HP SureStore E Disk Array XP512/XP48: Owner's Guide - HP StorageWorks XP512 | HP SureStore E Disk Array XP512/XP48 Owner's Guide - Page 101
P (1-3) D4 D8 D12 Figure 16. RAID5 with Parity Disk The downside to RAID0/1 over RAID5 is that there is a 100% overhead on storage redundancy associated with RAID0/1. RAID0/1 is often referred to as mirrored storage, because the user data is physically duplicated in the array. RAID Technology 101 - HP StorageWorks XP512 | HP SureStore E Disk Array XP512/XP48 Owner's Guide - Page 102
by generating parity data based on the data stored. RAID5 only requires a 33% storage overhead. Table 15.

of 1 and a maximum of 16 spare disk drives. For both RAID0/1 and RAID5 array groups, any dynamic spare drive can back up any other disk drive of the same capacity, anywhere in the disk array, even if the failed disk and the spare disk are on different array control processor (ACP) pairs. The RAID - HP StorageWorks XP512 | HP SureStore E Disk Array XP512/XP48 Owner's Guide - Page 104
value. Since this processing is done in the background, the array can continue to accept host I/O requests. The data saved on spare disks is copied back into the original location after the drive with errors has been replaced with a new one. 104 HP SureStore E Disk Array XP512/XP48: Owner's Guide - HP StorageWorks XP512 | HP SureStore E Disk Array XP512/XP48 Owner's Guide - Page 105
