3.14.1 
Data Redundancy 
RAID1 or RAID10 are necessary for redundancy. With redundancy, both capacity and 
performance are sacrificed for reliability. With RAIDXpert2, extremely high performance is 
obtained even with redundant-type arrays. 
3.14.2 
Backup 
It is good practice to back up your data periodically in case of a catastrophic failure. Tape backup 
or other media can be used to secure your data. 
3.15 
Flexibility and Expansion Considerations 
Before configuring an array, consider the following points to enhance the flexibility of the 
RAID system. 
3.16 
Multiple RAID Levels 
With RAIDXpert2, different RAID levels can be created on the same disk, to adapt each array to 
the I/O that it processes. Also, more than one array can be created per disk. 
Depending on the array capacity and redundancy level, an existing array can be transformed to 
another RAID level, if the level of the array being used is not the optimal RAID level for the 
application. Also, different arrays with different characteristics can be built for different 
applications.
