steelvine ? storage processor usb 2.0 and esata to sata storage processor the SII5734 is a low-cost, single chip solution for single-drive external enclosures and external backup drives. this steelvine storage processor has two 3 gbps esata gen2m device ports, one 3 gbps esata host port and one usb 2.0 host port. the SII5734 fea- tures proprietary esata-based capacity expansion, which allows users to easily grow the capacity of an existing steelvine enabled device by adding additional drives. the new drives will appear to the host system as additional space in the existing steelvine volume. applications ? external storage enclosures ? backup storage devices key features ? usb 2.0 and esata host ports ? esata capacity expansion ? drive locking ? single-button backup ? raid modes: big (concatenation) and jbod product brief SII5734 system diagram SII5734 the SII5734 steelvine storage processor allows manufacturers to build a range of internal and external single-drive storage solutions that sup- port both usb and esata gen2m, the fastest interface for consumer storage. other features of the SII5734 include drive locking, single-button backup and support for advanced raid modes. extensive software developer kits are available from silicon image to support development and simplify product differentiation. the SII5734 also features drive locking, which helps protect users' data by allowing them to password lock directly attached and cascaded drives. if a locked drive is detached from its assigned computer or cascade, the data on the drive will be inaccessible until it is reconnected and unlocked with the user supplied password. single-button backup through third-party appli- cations is also supported.
esata-based capacity expansion with esata-based capacity expansion, the capacity of a SII5734 enabled external enclo- sure can easily be expanded by adding additional steelvine enabled devices in a cascaded topology. when in big mode, these additional devices will dynamically appear to the host system as increased storage capacity in the exist- ing steelvine volume.
