Disk Configurations 

B

 

 

 

Your storage system supports various types of disk configurations, including RAID 
(redundant array of independent disks), a disk subsystem that can increase 
performance, provide data protection, or both. 

 

l 

Linear

—A linear configuration is similar to using multiple hard disks in a regular 

computer. Each disk is an independent entity, and the data on it is self- 
contained. You can add or remove the disks without affecting the other disks. All 
the available disk space is used for data. 

 

If your storage system has only one disk, you must use a linear configuration. 
However, you can use a linear configuration for two, three, or four disks as well. 

 

l 

RAID 0

—Instead of writing all the data to one disk in a linear fashion, some 

bytes are written to one disk, and other bytes are written to another. 
Performance is faster because reading and writing activities can occur on 
multiple disks simultaneously. All the available disk space is used for data. 

 

For RAID 0, your storage system must have at least two disks. However, you 
can use RAID 0 with three or four disks as well, and the disks can be any size. 

 

l 

RAID 1

—In this configuration, all the data written to one disk is duplicated on the 

other disk. This offers greater data protection since if one disk fails, all your data 
is still intact on the other disk. However, using RAID 1 means only half your 
available disk space is used for data; the other half is used for a duplicate 
(mirror) of that data. 

 

You can use RAID 1 only if your storage system has only two disks. If the disks 
are not the same size, the smaller of the two disks is used for data, and the 
larger of the two disks is used as the mirror. 

 

If one disk fails, the other disk continues to make its data available. 

 

l 

RAID 5

—Like RAID 0, RAID 5 offers increased performance by distributing the 

data across multiple disks. But unlike RAID 0, RAID 5 also offers data 
protection. If your storage system has three disks of equal size, two thirds of 
each disk are used for data, and the remaining third contains the parity 
information needed to reconstruct either of the other two. In this way, if any of 
the three disks fails, it can be reconstructed when a new disk is installed in the 
storage system. 

 

If your storage system has four disks of equal size, three fourths of each disk 
are used for data, and the remaining fourth contains the parity information 
needed to reconstruct either of the other three. If any of the four disks fails, it 
can be reconstructed when a new disk is installed.
