| 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 todays 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
SiI3124, SiI3132 and Marvell 88SE6145, SPMH3726 - SATA II port
multiplier, a high reliable and extremely
fast variety of storage applications (RAID 0, 1, 5, 10,
Concatenated and
JBOD).
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.
