Maximum number of drives: 4
Fault tolerance: Excellent; complete redundancy
Performance: Good; some reduction in write performance
Other considerations: 50% reduction in useable space as the drives containing
the mirror is not available to the user; drives must be identical
SPARE DRIVE: This is used in conjunction with RAID 1 (mirroring) and allows the
computer to keep running in the event of a drive failure without user intervention, even if
it is the boot drive that has failed. Also referred to as RAID 1+S.
Minimum number of drives: 1 (requires an associated RAID 1 array)
Maximum number of drives: 1 (requires an associated RAID 1 array)
Fault tolerance: Adds seamless disaster recovery to a RAID 1 configuration
Performance: Not applicable
Other considerations: Drive is not available to the user; drive must be identical
to the models used in the associated RAID 1 array
After you select which RAID level you wish to use, you will have to select drives to
include in the array. Follow the on-screen prompts to complete the configuration. If you
wish to use the RAID 1+S (“spare drive”) option, you must configure a RAID 1 array first.
Deciding which RAID solution to implement has some important implications for the
performance of your system and the safety of your data. This is intended as a guide
only, so you should investigate the wealth of information available on the Internet or
consult with a computer system professional for further assistance in deciding which
solution will best meet your needs.
