The
EXP100
supports
redundant,
dual-loop
configurations
with
the
DS4000s
and
other
EXP100
units.
External
cables
and
small
form-factor
pluggable
(SFP)
modules
connect
the
controller
to
the
expansion
enclosure.
EXP100s
attached
to
supported
DS4000s
can
be
used
with
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
expansion
enclosure
provides
continuous,
reliable
service
and
uses
hot-swap
technology
for
easy
replacement
without
the
need
to
shut
down
the
system.
Up
to
eight
EXP100
units
can
be
connected
together
in
a
Fibre
Channel
loop,
providing
connections
to
a
maximum
of
112
hard
drives.
Important
There
are
three
types
of
EXP100
Environmental
Storage
Canister
