The
target
is
the
storage
device
itself
or
an
appliance
which
controls
and
serves
volumes
or
virtual
volumes.
The
target
is
the
device
which
performs
SCSI
commands
or
bridges
to
an
attached
storage
device.
iSCSI
Concepts
iSCSI
(Internet
SCSI)
is
a
protocol
which
encapsulates
SCSI
(Small
Computer
System
Interface)
commands
and
data
in
TCP/IP
packets
for
linking
storage
devices
with
servers
over
common
IP
infrastructures.
iSCSI
provides
high
performance
SANs
over
standard
IP
networks
like
LAN,
WAN
or
the
Internet.
IP
SANs
are
true
SANs
(Storage
Area
Networks)
which
allow
several
servers
to
attach
to
an
infinite
number
of
storage
volumes
by
using
iSCSI
over
TCP/IP
networks.
IP
SANs
can
scale
the
storage
capacity
with
any
type
and
brand
of
storage
system.
In
addition,
it
can
be
used
by
any
type
of
network
(Ethernet,
Fast
Ethernet,
Gigabit
Ethernet,
and
10
Gigabit
Ethernet)
and
combination
of
operating
systems
(Microsoft
Windows,
Linux,
Solaris,
Mac,
etc.)
within
the
SAN
network.
IP
‐
SANs
also
include
mechanisms
for
security,
data
replication,
multi
‐
path
and
high
availability.
