Introduction
This
chapter
describes
the
operating
specifications,
features,
and
components
for
the
IBM
TotalStorage
DS4100
storage
server
(hereafter
referred
to
as
DS4100
or
storage
server).
This
chapter
also
includes
a
list
of
hardware
that
comes
with
the
storage
server.
Overview
IBM
DS4000
solutions
support
the
large
and
growing
data
storage
requirements
of
business-critical
applications.
These
scalable
IBM
DS4000
solutions
offer
you
data
access
and
protection
to
meet
your
existing
enterprise
storage
requirements
and
prepare
for
the
future.
Designed
for
data
archival,
data
reference,
and
near-line
storage
applications,
the
DS4100
utilizes
the
latest
Serial
Advanced
Technology
Attachment
(SATA)
disk
drive
technology.
The
DS4100
supports
up
to
fourteen
1.5
Gbps
250
GB
SATA
disk
drive
modules,
offering
up
to
3.5
terabytes
(TB)
of
capacity
per
enclosure.
Note:
SATA
hard
drive
CRUs
cannot
be
interchanged
with
the
fibre-channel
hard
drive
CRUs
that
are
supported
in
other
DS4000
storage
products.
The
DS4100
can
be
used
in
storage
area
networks
to
satisfy
the
needs
of
various
fixed
content,
data-reference
applications
that
require
large
amounts
of
storage
capacity
but
do
not
have
the
high
utilization
and
access
characteristics
satisfied
by
fibre
channel
disk
drive
storage.
The
storage
server
provides
continuous,
reliable
service,
using
hot-swap
technology
for
easy
replacement
without
shutting
down
the
system.
IBM
currently
offers
two
versions
of
the
DS4100:
v
DS4100
base
storage
server
(Machine
Type
1724,
Model
100)
v
DS4100
single-controller
storage
server
(Machine
Type
1724,
Model
1Sx)
About
the
DS4100
base
storage
server
The
DS4100
base
(dual-controller)
storage
server
(Machine
Type
1724,
Model
100)
is
a
rack-mountable
storage
server
that
comes
with
two
RAID
controllers,
two
power
supplies,
and
two
cooling
units.
It
provides
dual,
redundant
controllers,
redundant
cooling,
redundant
power,
and
battery
backup
of
the
RAID
controller
cache.
The
DS4100
base
storage
server
is
designed
to
provide
maximum
host
and
drive-side
redundancy,
enabling
full
redundant
drive
loop
support
to
additional
disk
storage
capacity
in
the
drive
expansion
enclosures
via
the
drive
loop
port
from
each
RAID
controller.
In
addition,
each
RAID
controller
supports
direct
attachment
of
two
hosts
that
contain
two
fibre
channel
host
bus
adapters
each.
External
cables
and
small
form-factor
pluggable
(SFP)
modules
connect
the
storage
server
to
the
storage
expansion
unit
and
the
host
servers.
Up
to
seven
DS4000
EXP100
storage
expansion
units
can
be
connected
together
with
the
DS4100
base
storage
server
in
a
fibre-channel
loop,
providing
connections
to
a
maximum
of
112
hard
drives.
With
the
DS4100
base
storage
server,
you
can
configure
RAID-protected
storage
solutions
of
up
to
28
TB
(by
connecting
the
DS4100
base
storage
server
to
seven
drive
expansion
enclosures
with
250
GB
SATA
hard
drives),
providing
economical
and
scalable
storage
for
your
rapidly
growing
application
needs
for
limited
access,
data
reference
storage
capacity.
The
DS4100
base
storage
server
is
designed
with
redundant
2
Gbps
fibre
channel
