The following options are available:
•
Do not s et dis k confi gurati on
—If you have created disk volume
configuration or plan to create multiple disk configurations, select not to
initialize the disk drive s .
•
Single Dis k
—Uses the disk drives as single disk volumes. When a drive
failure occurs, all data is lost.
•
JBOD (Linear)
—JBOD lets you combine multiple disks of mixed capacities
into a single logical storage device. The capacity of the JBOD array is the
sum of the total capacities of the individual component disks (that is, it does
not have the limitation of RAID 1 where you lose some capacity when using
mixed sized dis k s). JBOD offers no performanc e increas e c ompa red to the
component disks. It has lower relia bility t han the co mponent disks, as the
failure of a single disk results in the failure of the whole array.
•
RAID 0
—Di str ibu t es d ata acr oss se ver al d is ks in a wa y whi ch t hat imp r ove s
speed and full capacity. All data on all disks will be lost if any single disk f ails.
•
RAID 1
—Use s two di sks (m irrored disks) which each store the same data, so
that data is not lost as long as one disk surviv es. Total capa cit y of the array
equals the capa cit y of the smaller dis k.
•
RAID 5
—Combines three or more disks in a way that protects data against
loss of any single disk. RAID 5 is applicable to the NSS 324 and NSS 326.
•
RAID 6
—Com bine s four or more disks in a way that protects data again st
loss of any two disk s . RAID 6 is applicable to the NSS 32 4 and NSS 326 .
