Product Information

Based on a radically new chip architecture, the SiI 3124™ is a single-chip PCI-X to 4-port Serial ATA (SATA) host controller, that takes SATA performance and features to enterprise levels. The chip is ideal for applications such as servers, workstations and storage systems that require maximum performance from their storage assets.

 

 



 The SiI 3124 comes in 2 versions: (1) the SiI3124-1 operates at 1st Generation SATA speeds of 1.5Gbps while (2) the SiI 3124-2 integrates Serial ATA II PHY technology capable of running SATA 2nd Generation speeds of 3Gbps. Both devices support SATA II Native Command Queuing and SATA 1.0 Tagged Command Queuing. In addition, both controllers support Port Multipliers with FIS based switching and are capable of driving backplanes or extended length cabling with programmable output strengths.

With the SiI 3124, Silicon Image provides customers with drivers for the Windows, Linux and Novell Netware operating systems for both RAID and non-RAID operations. Software RAID 0 (striping), RAID 1 (mirroring), RAID 1+0 (mirrored stripe), and RAID 5 (parity stripe) functions are supported through Silicon Image’s SATARaid™ RAID management software utility.

The SiI 3124 is designed for optimum performance. Multiple commands for each port are loaded into on-chip memory eliminating the need for host CPU intervention and minimizing PCI bus usage. Command execution engines dramatically reduce latency between commands, ensuring that drives stay fully loaded with queued commands.

The SiI 3124-2 extends Serial ATA to 3Gbps by leveraging the circuit innovation at the physical layer of Silicon Image’s industry-leading SATALink architecture.
