Note:
1.
All
values
for
capacity
and
extent
numbers
are
based
on
preliminary
data.
2.
Physical
capacities
are
in
decimal
gigabytes
(GB).
One
GB
is
one
billion
bytes.
3.
Although
disk
drive
sets
contain
4
drives,
arrays
use
either
4
or
8
drives.
4.
The
array
consists
of
1
data
drive
that
is
mirrored
to
1
copy
drive.
Two
other
drives
in
the
disk
drive
set
are
used
as
spares.
5.
The
array
consists
of
2
data
drives
that
are
mirrored
to
2
copy
drives.
6.
The
array
consists
of
3
data
drives
that
are
mirrored
to
3
copy
drives.
Two
other
drives
in
the
disk
drive
set
are
used
as
spares.
7.
The
array
consists
of
4
data
drives
that
are
mirrored
to
4
copy
drives.
