Manual
Storage
protocol,
such
as
iSCSI,
has
“two
ends”
in
the
connection.
These
ends
are
initiator
and
target.
In
iSCSI,
we
call
them
iSCSI
initiator
and
iSCSI
target.
The
iSCSI
initiator
requests
or
initiates
any
iSCSI
communication.
It
requests
all
SCSI
operations
like
read
or
write.
An
initiator
is
usually
located
on
the
host
side
(either
an
iSCSI
HBA
or
iSCSI
SW
initiator).
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
command
or
bridge
to
an
attached
storage
device.
