Overview
INWIN’s 12G SAS3 Backplanes equipped with Broadcom 35x36R Expander provide an industry
leading high performance and high stability of data transfer for storage server solution.
The backplanes support state-of-the art SAS3 12Gbps HDD/SSD and also backward compatible
with SAS 6Gbps, SATA 6Gps and SATA 3Gps HDD/SSD. The backplane has 8 * OcuLink
(SFF-8621) connectors and 8* U.2 (SFF-8639) connectors to accommodate 8 * 2.5”NVMe SSDs
per each backplane.
There are 3 MiniSAS HD (SFF-8643) wide ports on each backplane. one of them are defined as
host ports for connecting to RAID/HBA cards and the other is defined as the cascade port for
connecting to another backplane and/or storage enclosure (JBOD) by extending it to the rear
panel of the chassis through a SFF-8643 to SFF8644 cable.
2 piece of 2*3-Pin 5V and 2 piece of 2*4-Pin 12V power receptacles support up to
5V(40A)/12V(60A) current to satisfy the power needs of fully loaded HDDs (24 HDDs depends
on backplane model).
The backplane implemented with smart fan control feature to support wide variety of fan
modules by auto-calibrating the installed fan modules at system boot. This feature provides an
efficient way to control the thermal heat exhaustion by sensing the temperature on the
backplane. The fan module speeds up and down upon the temperature rises and falls in the
enclosure. Further, the backplane reserves a connector for adapting Fan PWM from
motherboard so backplane can leverage PWM request from motherboard and behave according
to the higher RPM number between MB and backplane.
Along with the smart fan control feature, a system alarming feature is also implemented to alert
users in case Fan module failure and/or system overheat occurs by illuminating the LED
indicator. Users can then informed of issue and take corresponding actions to resolve the issue
according to the failure type.
