FICON-attached
System
z
and
S/390
hosts
overview
This
section
describes
how
you
can
attach
the
DS8000
storage
unit
to
FICON-attached
System
z
and
S/390
hosts.
Each
storage
unit
fibre-channel
adapter
has
four
ports.
Each
port
has
a
unique
worldwide
port
name
(WWPN).
You
can
configure
the
port
to
operate
with
the
FICON
upper-layer
protocol.
For
FICON,
the
fibre-channel
port
supports
connections
to
a
maximum
of
509
FICON
hosts.
On
FICON,
the
fibre-channel
adapter
can
operate
with
fabric
or
point-to-point
topologies.
With
fibre-channel
adapters
that
are
configured
for
FICON,
the
storage
unit
provides
the
following
configurations:
v
Either
fabric
or
point-to-point
topologies
v
A
maximum
of
64
host
adapter
ports
on
DS8100
Models
921
and
931,
and
a
maximum
of
128
host
adapter
ports
on
DS8300
Models
922,
932,
9A2,
and
9B2
v
A
maximum
of
509
logins
per
fibre-channel
port
v
A
maximum
of
8192
logins
per
storage
unit
v
A
maximum
of
1280
logical
paths
on
each
fibre-channel
port
v
Access
to
all
255
control-unit
images
(8000
CKD
devices)
over
each
FICON
port
v
A
maximum
of
512
logical
paths
per
control
unit
image.
Note:
FICON
host
channels
limit
the
number
of
devices
per
channel
to
16
384.
To
fully
access
65
280
devices
on
a
storage
unit,
it
is
necessary
to
connect
a
minimum
of
four
FICON
host
channels
to
the
storage
unit.
You
can
access
the
devices
through
a
switch
to
a
single
storage
unit
FICON
port.
With
this
method,
you
can
expose
64
control-unit
images
(16
384
devices)
to
each
host
channel.
The
storage
unit
supports
the
following
operating
systems
for
System
z
and
S/390
hosts:
v
Linux
v
Transaction
Processing
Facility
(TPF)
v
