Applications
The SiI5733 is a low-cost, single chip solution designed to be built into DVR’s, PC mother-
boards, and consumer electronic devices. This SteelVine Storage Processor has a 3Gbps
SATA host interface and two eSATA capable device ports. In addition to patent-pending
eSATA based capacity expansion, the SiI5733 features automatic drive locking, which
protects data stored on an external drive by locking it to the SiI5733 using a unique built in
password. Once locked, the data will only be accessible when attached to the SiI5733
with the proper password. This protects use data and provides a secure link to external
drives for digital rights management applications.
The SiI5723 SteelVine Storage Processor extends
the capabilities of consumer electronics and DVR
devices as well as PC motherboards with advanced
storage features on a single chip that easily inte-
grates with existing designs via a SATA connection.
With eSATA based capacity expansion the storage
capacity of the SiI5723 enabled motherboard or
device can be easily expanded either by adding
additional drives or by adding additional SteelVine
enabled devices in a cascaded topology. When in
BIG mode, these additional drives or devices will
dynamically appear to the host system as increased
storage capacity in an existing SteelVine volume. In
addition, the SII5723 supports single-button
backup through third-party applications for simple
and worry-free data protection.
SiI5723 storage processors support JBOD and the
following RAID modes: FAST(RAID 0), SAFE

(RAID 1) and BIG (Concatenation) as well as two
new ‘multi-RAID’ modes, SAFE33, and SAFE50.
Multi-RAID modes automatically create two vir-
tual volumes, one SAFE and the other BIG and are
designed to balance the benefits of capacity and
protection with only two drives. SAFE50 divides
the physical space on each drive equally to create
each virtual volume. In SAFE33, two-thirds of the
available physical space is used to create the BIG
partition, and the remaining one-third is used for
the SAFE partition. When adding two drives to the
SiI5723, BIG, FAST, SAFE, SAFE33, SAFE50 and
JBOD are supported. When drives are cascaded,
BIG, SAFE, SAFE33 and SAFE50 are available.
RAID mode configuration can be accomplished
through a GUI, strap pins, or I2C for true soft-
ware-free implementations.

SiI5733 Automatic
Drive Locking
Drives are locked to the storage
processor using the ATA maxi-
mum
security
mode.
This
access control approach pre-
vents all attached drives from
being
read
until
they
are
unlocked. A 128-bit secret key,
which is not accessible to the
host,
is
burned
into
the
SiI5723. This unique password
will lock and unlock all drives
automatically, including cas-
caded drives. This feature
can be used as part of an
overall DRM scheme to lock
a drive or set of cascaded
drives to a single specific
host PC, STB, or DVR.
