This configuration supports a zero wait state, 32-bit memory transfers at 160 MB per second, when low voltage differential (LVD) SCSI peripherals are attached. This channel supports up to 15 SCSI devices. In addition, the SCSI adapter uses: v Double-transition clocking to achieve high transfer rates v Domain name validation to negotiate compatible data transfer speeds with each device v Cyclic-redundancy checking, instead of the usual parity checking, to significantly improve data reliability Note: If you install a RAID adapter, you can move the SCSI signal cable from the SCSI connector on the SCSI adapter to an internal channel connector on the RAID adapter to control the internal drives from the RAID adapter. SCSI cabling requirements You can install five internal SCSI devices using the SCSI signal cable that comes with the server or purchased separately, depending on the server model.

uses
an

located
in
the
AGP
slot
on
the

board.
There
is
a
15-pin
analog
video
connector
located
on
the
rear
of
the
server.
See
“I/O

on

for
the

of
this

Ultra160
SCSI
connector
(some
models)
Some
xSeries
200
server
models
come
with
a
SCSI
adapter,
which
supports
a
single
Ultra160
SCSI
channel
in
a
full-featured
PCI
2.1-/2.2-compliant
bus
master
package.
This
configuration
supports
a
zero
wait
state,
32-bit
memory
transfers
at
160
MB
per
second,
when
low
voltage
differential
(LVD)
SCSI
peripherals
are
attached.
This
channel
supports
up
to
15
SCSI
devices.
In
addition,
the
SCSI
adapter
uses:
v
Double-transition
clocking
to
achieve
high
transfer
rates
v
Domain
name
validation
to
negotiate
compatible
data
transfer
speeds
with
each
device
v
Cyclic-redundancy
checking,
instead
of
the
usual
parity
checking,
to
significantly
improve
data
reliability
Note:
If
you
install
a
RAID
adapter,
you
can
move
the
SCSI
signal
cable
from
the
SCSI
connector
on
the
SCSI
adapter
to
an
internal
channel
connector
on
the
RAID
adapter
to
control
the
internal
drives
from
the
RAID
adapter.
SCSI
cabling
requirements
You
can
install
five
internal
SCSI
devices
using
the
SCSI
signal
cable
that
comes
with
the
server
or
purchased
separately,
depending
on
the
server
model.
