The IntelliProp IPP-SA128A-PM (SATA Port Multiplier with Sandbox) device is an IP core that provides SATA Port Multiplier functionality with support for up to 15 SATA storage devices. The IP core is comprised of an industry compliant design to support port multiplier and SATA bridging applications, so time to market and integration costs are reduced by leveraging existing investments in SATA bridging logic. The SATA compatible logic cores can be connected to any standard SATA interface, and will automatically negotiate to compatible connection speeds.
The SATA Port Multiplier contains four specific blocks. The Host Port contains a SATA Device IP core and connects to the PC. Frames are transferred to the Bridging logic and if required the Customer Specific Logic. Based on routing information the frames are routed to the correct SATA Drive through the Device Port. Return frames from the Device Port are checked for the port field and updated prior to going through the Bridging Logic and Customer Specific Logic to the Host Port and finally to the PC.
