LED Status Description
ON
SPAN: Spanning concatenates multiple hard drives
into a single large disk. Provides no performance or
redundancy benets.
OFF
ON
RAID 0 (Stripe): Striping combines multiple disk into
a single large disk array. The data is split evenly across
each disk simultaneously. Read/write performance
is increased as a result, but failure of any one disk will
make the entire array unusable.
OFF
ON
RAID 1 (Mirror): Mirroring writes the same data across
multiple disk, creating a mirror copy. This provides
redundancy in case one drive fails.
OFF
ON
RAID 3: Uses striping to write data to multiple disks
like RAID 0, but reserves one disk for parity. The single
parity disk is a bottle-neck for writing since every write
requires updating the parity data. Failure of any one
disk will still allow access to the data, until the disk is
replaced.
OFF
ON
RAID 5: Uses striping to write data to multiple disks
simultaneously and distribute parity across multiple
disks. Failure of any one disk will still allow access to the
data, until the disk is replaced.
OFF
ON
RAID 01 (0+1): Creates a mirrored array, then stripes
each mirrored disk. Combines the performance of RAID
0 with the redundancy of RAID 1.
OFF
