RAID technologies
Selecting the right RAID type for your IT infrastructure
The RAID setting that you select is based upon the following:
• The number of parity groups that you have
• The fault tolerance required
• The write performance required
• The amount of usable capacity that you have
Configuring the RAID fault tolerance
If your IT environment requires a high level of fault tolerance, select a RAID level that is optimized for fault
tolerance.
This chart shows the relationship between the RAID level fault tolerance and the size of the storage array.
The chart includes RAID 0, 5, 50, 10, 6, and 60. It also shows the percent reliability in increments
between 1 and one billion and the storage array drive increments between 0 and 96.
This chart assumes that two parity groups are used for RAID 50 and RAID 60.
This chart shows that:
• RAID 10 is 30,000 times more reliable than RAID 0.
• The fault tolerance of RAID 5, 50, 6, and 60 decreases as the array size increases.
8Features

Configuring the RAID write performance
If your environment requires high write performance, select a RAID type that is optimized for write
performance
The chart below shows how RAID 10, 5, 50, 6, and 60 compare to the percent write performance of RAID
0.
The data in the chart assumes that drives are limited and that drive write performance is the same as
drive read performance.
Consider the following points:
• Write performance decreases as fault tolerance improves due to extra I/O.
• Read performance is generally the same for all RAID levels except for smaller RAID 5\6 arrays.
The table below shows the Disk I/O for every host write:
RAID type Disk I/O for every host write
RAID 0 1
RAID 10 2

Features 9

RAID type Disk I/O for every host write
RAID 5 4
RAID 6 6
Configuring the RAID usable capacity
If your environment requires a high usable capacity, select a RAID type that is optimized for usable
capacity. The chart in this section demonstrates the relationship between the number of drives in the
array and the percent usable capacity over the capacity for RAID 0.
Consider the following points when selecting the RAID type:
• Usable capacity decreases as fault tolerance improves due to an increase in parity data.
• The usable capacity for RAID 10 remains flat with larger arrays.
• The usable capacity for RAID 5, 50, 6, and 60 increases with larger arrays.
• RAID 50 and RAID 60 assumes two parity groups.
Note the minimum drive requirements for the RAID types, as shown in the table below.
RAID type Minimum number of drives
RAID 0 1
RAID 10 2
RAID 5 3
RAID 6 4
RAID 50 6
RAID 60 8
