SATAPMH141 is 1-to-4 SATA Port Multiplier that allows
a single SATA host port to communicate with up to 4 SATA device ports
and one SEMB port. With its unique data aggregation capability and 3Gbps
serial link capability, the SATAPMH141 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 SATAPMH141 supports all the
port multiplier related SATA II extensions allowing system designers to
exploit the full potential of SATA in their storage solutions.
The SATAPMH141 supports host and device link rates of 1.5Gbps and 3Gbps
with auto-negotiation. Additionally, the SATAPMH141 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/Sil3132
and Marvel 88SE61xx (88SE6111, 88SE6121, 88SE6145), SATAPMH141 - SATA
II port multiplier, a high reliable and extremely fast variety of storage
applications (RAID 0, 1, 5, 10, Concatenated and JBOD).
SATAPMH141 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.
