Virtualize
the
array.
Before
putting
an
array
into
use,
you
need
to
virtualize
the
array.
Specifically,
select
the
array
from
the
Virtualization
Array
area,
and
then
click
Virtualization
.
NOTE
！
It
takes
a
while
to
virtualize
an
array.
Wait
patiently.
After
the
virtualization
is
complete,
the
Virtualized
column
of
the
array
is
displayed
as
Yes
in
the
array
list.
The
virtualized
array
can
be
used
for
storage
configuration.
NOTE
！
The
types
of
arrays
are
described
as
follows:
z
JBOD:
JBOD
allows
multiple
hard
disks
to
be
accessible
as
one
logical
volume.
The
use
of
JBOD
increases
the
access
speed
and
utilization
of
the
hard
disks,
but
it
offers
lower
level
of
reliability
because
the
array
cannot
operate
properly
when
any
of
the
arrayed
disks
fails..
In
addition,
only
one
JBOD
array
can
be
built
with
one
hard
disk.
z
RAID1:
Data
redundancy
is
implemented
by
hard
disk
data
mirroring,
and
data
that
backs
up
each
other
is
generated
on
hard
disks
in
pairs.
RAID1
ensures
the
availability
and
recoverability
of
user
data
to
the
utmost
extent.
It
is
slow
to
build
an
RAID1
array.
One
RAID1
array
can
be
built
with
only
two
hard
disks
of
the
same
capacity.
z
RAID5:
Multiple
hard
disks
are
combined
into
a
striped
array
with
parity
check.
RAID5
has
data
redundancy.
When
one
hard
disk
of
an
RAID5
array
is
damaged,
the
array
can
still
work
properly,
thereby
ensuring
the
reliability
of
data
storage.
To
create
an
RAID5
array,
you
need
at
least
three
hard
disks
of
the
same
capacity.
DVR200
series
does
not
support
RAID5.
Checking
an
array
and
the
slot
list
You
can
check
an
array
list
for
information
about
the
array
in
which
a
hard
disk
resides,
and
check
a
slot
list
for
information
about
the
physical
hard
disk
corresponding
to
each
slot.
Select
a
slot
list
from
the
S.M.A.R.T.
Info
area,
and
then
click
S.M.A.R.T.
Info
to
check
the
running
status
of
the
hard
disk
corresponding
to
the
slot.
Rebuilding
an
array
When
one
hard
disk
of
an
RAID1
or
RAID5
is
damaged,
the
array
information
status
bar
indicates
that
the
status
is
Degrade
.
In
this
case,
you
need
to
rebuild
the
array,
so
that
a
new
hard
disk
can
replace
the
faulty
hard
disk
and
the
array
can
be
restored.
