This
method
uses
Ethernet
connections
from
a
management
console
to
each
controller.
The
management
station
can
be
the
host
or
a
workstation
on
the
Ethernet
network.
Each
RAID
controller
must
have
connectivity
to
each
other
and
to
your
Storage
Management
Console.
Use
the
Ethernet
interface
ports
on
each
RAID
controller
at
the
rear
of
the
storage
enclosure
to
connect
a
pair
of
Ethernet
cables
from
the
Storage
Management
Console
to
the
controllers
for
direct
management.

or
an

are
available
in

A
minimum
of
two
disk

codes
(8
drives)
are
required
(see
Table
6)
for
your
DS6000
series
configuration.
You
also
can
order
additional
storage
capacity
to
your
base
enclosure
or
to
an
expansion
enclosure.
They
also
must
be
a
minimum
of
two
feature

(8
drives).

Capacity
calculation
guidelines
To
help
you
determine
the
type
and
number
of
disk
drives
to
add
to
your
storage
unit,
calculate
the
physical
and
effective
capacity
of
the
disk
drives.
Calculating
physical
and
effective
capacity
To
calculate
the
total
physical
capacity
of
a
DS6000
series,
multiply
each
disk
drive
set
feature
by
its
total
physical
capacity
and
sum
the
values.
The
logical
configuration
of
your
DS6000
series
storage
affects
the
effective
capacity
of
the
disk
drive
set.
Specifically,
effective
capacities
depend
on
the
following:
v
Whether
the
physical
capacity
is
logically
configured
as
fixed
block
(FB)
or
count
key
data
(CKD)
Data
for
open
systems
must
be
logically
configured
as
FB.
Open
systems
hosts.
Data
for
zSeries
must
be
configured
as
count
key
data
(CKD).
v
How
the
arrays
on
the
system
are
combined
into
ranks
One
or
more
arrays
are
combined
to
create
a
contiguous
storage
space
called
a
rank.
Each
rank
is
divided
into
DS6000extents.
The
effective
capacity
for
FB
extents
will
be
different
than
the
capacity
for
CKD
extents.
