based on the proven steelvine storage processor architecture, the sii 4726 ? provides a new level of affordable storage for professional users. the sii 4726 provides 3gb/s sata performance over the single host sata link as well as the five device sata links, and can be configured for internal or external (esata) applications. until now, transfer rates of 3gb/s and hardware raid features, were only available to enterprise class applications. sii 4726 allows oems and system integrators to offer high-end features for price-sensitive professional market applications. users of the sii 4726 can eliminate cpu loading by using the embedded risc storage processor, which was developed by silicon image, and tuned for the needs of storage applications. this storage processor completely frees up the main cpu and provides the enhanced raid modes 3 . the device can be configured using the gui, to provide reliab le data mirroring, data performance striping, or just plain capacity expansion. the sii 4726 modes are; 1) safe or data mirroring (raid 1) allows device to auto- matically copy primary hard drive without any cpu loading 3 . the sii 4726 provides automatic rebuild on device replacement and auto-failover, to eliminate any workflow interruptions. 2) fast or data striping (raid 0) allows the device to performance str ipe the dr iv es, to provide maximum throughput to the direct attached pc/server. 3) big or drive spanning allows the device to make any two drives (same or diff erent siz es) appear as one lar ge dr iv e to the host, f or extr a capacity (also called con - catenation). 4) jbod or p or t multiplier this allo ws the direct attached pc/ser v er to see each drive as just a bunch of drives. 5) fast&safe or data striping and mirroring (raid 10) allows the device to improve data availability beyond raid 5 or raid 6 with lar ge sata drives, due to rebuild vulnerability. 6) big&safe drive spanning and mir roring allows for large capacity with protection. the sii 4726 works with any serial ata compliant host port, although some features such as jbod access require a port multiplier aware host controller such as sii 3124-2 ? or sii 3132 ? . for more details, please contact your local silicon image sales representative. applications ? video editing ? digital video recording systems ? nearline das storage ? external storage enclosur es ? protected soho/smb storage si i 4726 sata to 5-port sata device steelvine ? storage processor host sata port si i 4726 sata ii to 5-port sata ii stor age processor 3gb/s sy ste m stat us fdd power regulators ee prom gpi os l eds 3gb/s 3gb/s 3gb/s 3gb/s po rt b po rt a po rt d po rt c po rt e 3gb/s
