SII5923

Product Brief SiI 5923 SteelVine® Series 3 Core Third Generation SATA-to-Dual eSATA Storage Processor The SteelVine® Series 3 Core storage processor is a low-cost, single chip solution • CE Motherboards Applications • PC Motherboards • DVR Motherboards designed to be built into PC motherboards, DVRs and consumer electronics devices. It features a 3Gbps SATA host interface and two eSATA capable device ports. The SiI5923 features Silicon Image performance RAID, which allows users to easily speed up or add automatic back up by adding additional drives as needed. Key Features • Storage Offload Engine (100%) • eSATA capable device ports The SteelVine Series 3 Core storage processor extends the capabilities of PC motherboards, DVR devices, and consumer electronics by adding eSATA and advanced storage features on a single chip that easily integrates with existing designs via a SATA connection. Advanced features include enhanced sector recovery and automatic data repair to provide higher levels of protection for your customer’s critical data. Management parameters can be customized using the Manufacturing Utility or through customer applications built using the SiI5923 Software Development Kit. SiI5923 storage processor supports JBOD and the following RAID modes: FAST (RAID 0) and SAFE (RAID 1). RAID mode configuration can be accomplished through a System Management Bus (SMBus)-based GUI or strap pins for true software-free implementation. • RAID 1 performance (racing) • RAID 1 rebuild boost • Easy to Use Auto Mirror / Failover • High Performance The SiI5923 reduces your power budget by entering aggressive power-down modes when drive(s) are idle or not present. The economical 40-pin QFN package offers a small footprint implementation. - Hardware acceleration SiI5923 System Diagram JBOD, SAFE, or FAST Southbridge SATA 3G Host SMBus Mode Select LEDs SiI5923 SteelVine® Series 3 Core SATA 3G Port 0 HDD 0 SATA 3G Port 1 HDD 1 SiI5923 RAID 1 Read Racing Hard drives spinning at 7200 RPM require 8.3 milli-seconds for one rotation. The two drives in a RAID 1 pair are not synchronized and are at random locations in relation to the data requested. The worst case is when a complete rotation is needed to reach the data, causing a full 8.3 ms delay. To minimize this delay, SiI5923 directs reads to a specific port to minimize proximity from the address read last. The result is to reduce the average time for RAID 1 reads.
