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 integrates 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 virtual 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 software-free implementations.
