RAID Arrays
NVRAID supports the followng types of RAID arrays descrbed n ths secton:
■ RAID 0: RAID 0 defines a dsk strpng scheme that mproves the dsk read and
wrte tmes for many applcatons.
■ RAID 1: RAID 1 defines technques for mrrorng data.
■ RAID 0+1: RAID 0+1 combnes the technques used n RAID 0 and RAID 1 ar-
rays.
■ RAID 5: RAID 5 defines technques for party data.
■ Spannng (JBOD): JBOD provdes a method for combnng drves of dfferent szes
nto one large dsk
