steelvine ? storage processor sata to dual esata storage processor the steelvine sii5723 storage processor is a low-cost, single chip solution designed to be built into dvrs, pc motherboards and consumer electronics devices. it features a 3gbps sata host interface and two esata capable device ports. the sii5723 features silicon image?s proprietary esata based capacity expansion, which allows users to grow the capacity of an existing steelvine enabled device by adding additional drives that appear to the host system as additional space in the existing steelvine volume. applications ? dvr motherboards ? pc motherboards ? ce devices key features ? esata capable device ports ? esata capacity expansion ? drive locking ? backup button ? raid modes: fast (raid 0), safe (raid 1), safe33, safe50 big (concatenation) product brief sii5723 system diagram si i 5723 the steelvine sii5723 storage processor extends the capabilities of consumer electronics and dvr devices as well as pc motherboards by adding esata, capacity expansion, drive locking, single- button backup support and other advanced stor- age features on a single chip that easily integrates with existing designs via a sata connection. drive locking helps protect users data by allow- ing 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. 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 sup- ported. when drives are cascaded, big, safe, safe33 and safe50 are available. raid mode configuration can be accomplished through a gui, strap pins, or i 2 c for true software-free implementations.
esata-based capacity expansion with esata-based capacity expansion, the capacity of a sii5723 enabled motherboard or appliance can be easily expanded either by adding additional drives directly to the processor, or by adding addi- tional steelvine enabled devices in a cascaded topol- ogy. when in big mode, these additional drives or devices will dynamically appear to the host system as increased storage capacity in an existing steelvine vol- ume. sii 5723 features serial ata host interface features ? serial ata gen2m compliance ? esata and 2-meter cable support ? 3 gbps (auto-negotiates to 1.5 gbps) ? compatible with pm aware and non-pm aware hosts ? allows multiple drives to be accessed by non- pm aware drive hosts ? supports ncq device interface features ? serial ata gen2m compliance ? esata and 2-meter cable support ? 3 gbps (auto-negotiates to 1.5 gbps) ? independent 8 kb fifo / port ? power management capabilities ? supports hot plug ? supports atapi & asynchronous notification electrical specifications ? gpio pins: 9 gpi, 6 gpo ? 3.3v io supply, 1.8v core supply ? 1.02 watts (typical) environmental ? operating temperature: 0oc to 70oc ? operating relative humidity: 5% to 80% ? non-operating relative humidity: 5% to 95% physical specifications ? 88-pin qfn ? 10mm x 10mm additional steelvine features ? no driver, bios or software required ? user api interface through i 2 c ? no drive reformatting on raid change ? email notification ? optional xml api ? raid 1 drive racing ? optional steelvine manager gui ? mandatory smart commands available ? safe later ? 2006 silicon image, inc. all rights reserved. silicon image, the silicon image logo, steelvine, the steelvine logo, sii and sii5723 are trademarks or registered trademarks of silicon image, inc. in the united states and other countries. other trademarks are property of their respective holders. product specifications are subject to change with out notice. part number: sii5723 sii pb-62 rev3 12/06 silicon image, inc. 1060 e. arques avenue sunnyvale, ca 94085 t 408.616.4000 f 408.830.9530 www.siliconimage.com capacity expansion diagram block diagram
