SPMH3726 is 1-to-5 SATA Port Multiplier designed to provide a high performance link between a single SATA host port and 5 SATA device ports. With its unique data aggregation capability and 3Gbps serial link capability, the SPMH3726 is able to take full advantage of 3Gbps host link bandwidth and FIS-based switching host controllers by bundling together data from device ports and sending it over the 3Gbps host link. Additionally, the feature-rich SPMH3726 supports all the port multiplier related SATA II extensions allowing system designers to exploit the full potential of SATA in their storage solutions.

The SPMH3726 supports host and device link rates of 1.5Gbps and 3Gbps with auto-negotiation allowing system designers to utilize 3Gbps host links with today’s 1.5Gbps hard drives, and to futureproof designs for the emergence of 3Gbps SATA hard drives. Additionally, the SPMH3726 contains a SATA enclosure management bridge (SEMB) to pass in-band enclosure management information between the host and an enclosure management device. Other important features include, programmable high drive capability for backplane and external applications, asynchronous notification to eliminate the need for host polling to determine if a device has been added or removed, and hot plug support.

Coupling with proper host controllers such as Silicon Image Sil3124 and Sil3132, SPMH3726 - SATA II port multiplier, a high reliable and extremely fast variety of storage applications (RAID 0, 1, 5, 10, Concatenated and JBOD).

• SATA2-PCIE02 is 2-port SATAII to PCI Express RAID Host Adapter (Silicon Image Sil3132)
• SATA2-PCIX01 is 4-port SATA to PCI-X Host Adapter (Silicon Image Sil3124)

SPMH3726 delivers the performance and connectivity required for servers and I/O demanding applications such as CD-ROM servers, Video-On-Demand (digital content and high-definition video), database servers, workstations, high-end desktops, software RAID sub systems, and image systems.
