Data
cartridge
capacity
scaling
The
SET
CAPACITY
SCSI
command
enables
a
customer
to
capacity
scale
a
data
cartridge
to
enable
faster
random
access.
As
an
example,
a
customer
could
capacity
scale
a
data
cartridge
to
20%
of
its
normal
length
which
improves
the
average
access
time
by
almost
a
factor
of
5;
however,
it
also
reduces
the
native
capacity
of
the
tape
to
80
GB.
Encryption
This
drive
supports
host
Application
Managed
Encryption
(AME),
using
T10
encryption
methods.
Data
encryption
is
supported
with
LTO
Ultrium
4
Data
Cartridges
only.
The
encryption
enabled
drive
contains
the
necessary
hardware
and
firmware
to
encrypt
and
decrypt
host
tape
application
data.
Encryption
policy
and
encryption
keys
are
provided
by
the
host
application
and
there
is
no
encryption
setup
required
(or
available)
for
this
drive.
A
drive
digital
certificate
is
installed
at
manufacturing
time.
Each
drive
receives
a
unique
serial
number
and
certificate.
The
T10
Application
may
validate
each
drive
instance
by
checking
the
drive’s
digital
certificate.
Application-managed
encryption
is
supported
on
AIX
®
,
Windows
Server
2003,
Linux
®
,
and
Solaris.
Encryption
requires
the
latest
device
drivers
available
on
the
ftp
down
load
site:
ftp://ftp.software.ibm.com/storage/devdrvr/.
For
more
details,

documentation,
and
the
IBM
LTO
Ultrium
Tape
Drive
SCSI
Reference
documentation.
Inhibit
firmware
down-leveling
The
drive
provides
the
capability
to
prevent
loading
and
installing
drive
microcode
via
a
Field
Microcode
Replace
(FMR
tape)
if
the
firmware
level
contained
in
the
FMR
tape
is
older
than
the
code
level
already
installed.
This
option
is
controlled
by
the
host
application.
No
checking
will
be
performed
if
the
firmware
level
is
loaded
via
the
host
interface
or
the
library
interface.
SAS
interface
The
drive
has
a
single-port
3
Gbps
SAS
(Serial
Attached
SCSI)
host
interface.
A
drive
with
a
SAS
interface
can
be
linked
directly
to
controllers.
SAS
is
a
performance
improvement
over
traditional
SCSI
because
SAS
enables
multiple
devices
(up
to
128)
of
different
sizes
and
types
to
be
connected
simultaneously
with
thinner
and
longer
cables;
its
full-duplex
signal
transmission
supports
3.0
Gb/s.
In
addition,
SAS
drives
can
be
hot-plugged.
SAS
drives
will
auto-negotiate
speed.
There
are
no
configurable
topologies
thus
no
feature
switches
associated
with
SAS.
Physical
Characteristics
The
drive
contains
a
single-port,
SFF-8088
SAS
connector.
